At the time this was the largest oceanic displacement or migration in history, eclipsing even the far-flung, but less-dense, expansion of Austronesian-Polynesian explorers.
The number of Africans who arrived in each region is calculated from the total number of slaves imported, about 10,000,000

" The principal source of precipitation in California is moisture laden marine air moving in from the Pacific Ocean. The storm systems that deliver the moisture generally
originate in the Gulf of Alaska and occasionally in the eastern Pacific Ocean. A semi-permanent high-pressure system located off the State's coast tends to regulate the movement of
Pacific storms and is a key feature of the atmospheric-circulation patterns that determine California's climate (Officials of the National Oceanic and Atmospheric Administration, 1974).
The position of this high-pressure system affects the seasonal distribution of precipitation and the erratic multiyear periods of greater than normal or less than normal precipitation.
The geographic distribution and intensity of precipitation are determined by the Pacific storm track in combination with the State's topography. "
" Precipitation is rare during the summer. The Pacific high pressure area off the northern California coast keeps storm tracks well to the north. Occasionally, moist air moves
in from the subtropical Pacific Ocean during the summer and results in scattered thundershowers that are sometimes locally intense in the deserts and mountains. "
" Most precipitation in California is received during the storm season from November to March. In winter, the Pacific high-pressure system generally moves southward, allowing
storms from the Gulf of Alaska to move across California. These storms commonly are a series of frontal systems 2 or 3 days apart. Because of the usual pattern of storm movement,
precipitation quantities are generally greatest in the north and progressively less toward the south. Variations in the circulation pattern at times cause storms to approach California
from the southwest, thus bringing warm, moist air from the tropics. On occasion, when this inflow of air from the southwest converges with a contrasting flow of cold air from the Arctic,
the results are devastating. The floods of December 1955, December 1964, and February 1986 were caused by storms of this type. If the Pacific high-pressure system fails to move south
during the winter, winter storms are blocked, are diverted to the north of California, or are severely weakened. A persistence of this condition leads to drought in the State
(California Department of Water Resources, 1978). "
" Mountain ranges induce precipitation at the higher altitudes and create "rain shadows (dry areas)" in the leeward valleys and plains. In California, nearly
continuous ranges of coastal mountains extend from the Oregon border to Mexico, and these ranges are paralleled by the southern Cascade Range and the Sierra Nevada roughly 150
miles inland (fig. 1). Between the two ranges lies the Central Valley, nearly 400 miles long and 70 miles wide. To the east of the southern Cascade Range, the Sierra Nevada,
and the coastal mountains of southern California are the Basin and Range and the
Southern California Desert provinces. "
" The higher mountain areas, principally the Sierra Nevada, receive much of the annual precipitation as snow, which accumulates during winter and melts in spring; this important
feature of California's hydrology provides a natural reservoir to moderate the uneven seasonal distribution of precipitation. Storage in the form of snow commonly decreases the severity
of peak flows, but it also has contributed to some of the State's worst floods when warm rains melted the snow. Unusually large snow packs, like those in 1969, have caused flooding as a
result of the large volume of runoff during the spring snowmelt. "

"The droughts of 1928-37 and 1976-77 are the events to which other droughts commonly are compared. Both droughts were severe, and one or the other is cited by different sources as
the worst in the State's recorded history. Because their durations were so different, comparisons between the two droughts are difficult, yet they illustrate the diversity of events
characterized as droughts. The droughts of 1943-51 and 1959-62, although less severe, were relatively well defined and of statewide significance. The same is true of the current (1989)
ongoing drought that began in 1987.

1917-1921; The draught of 1917-1921 was statewide, except central Sierra Nevada and north coast, with a recurrence interval that ranged from about 10 to 40 years, depending on
location. The most severe was in northern western Calaforina.
1922-26: Statewide, except central Sierra Nevada. Simultaneously in effect for entire State only during 1924, which was particularly severe.
1928-37: Statewide >100 Simultaneously in effect for entire State, 1929-34. Longest, most severe in State's history.

Moderate to heavy rains fell across southeast California and Arizona, with a new 24-hour maximum for Arizona 12 inches (305 mm) falling in the Mogollon Rim. Damage totaled several hundred million, including $40 million (1997 USD) to lemon trees. There were a few indirect deaths caused by the hurricane.
2001, September: Remnant moisture from Hurricane Flossie caused thunderstorms, lightning, and floods in southern California. Lightning struck four people, killing two of them.
2001, September 30: Thunderstorms from the remnants of Hurricane Juliette caused minor damage to California and brought rain of less than an inch (25 mm) to the area.
2003, August: Remnants of Hurricane Ignacio produced powerful thunderstorms in southern California.
2003, September: Remnants of Hurricane Marty dropped large amounts of rainfall, in the southwestern United States, especially in southern California and southwestern Arizona.
2006, July: Remnants of Tropical Storm Emilia caused unsettled weather across the southwestern United States. Rain from the remnants helped to extinguish the Horse Fire in southern California.
2006, September: Remnants of Hurricane John triggered flash flood watches.
2007, August 26-27: Remnants of Hurricane Dean made landfall in Santa Barbara area, triggering heavy rains and minor flooding throughout the southern California Area. Early on August 27, the storm eventually reached Las Vegas, Nevada, and caused flash flooding there as well, before dissipating there later in the day.
2008, August 25: Remnants of Tropical Storm Julio reached Apple Valley, California, and Las Vegas, Nevada.
2009, August 27-29: Remnants of Tropical Storm Ignacio triggered heavy rains across northern and central California.
2009, September 4: Remnants of Hurricane Jimena caused severe thunderstorms to break out in eastern San Diego County, causing flash floods, and a short blackout that lasted for only a few hours.
2009, October 11-15: The remnants of Typhoon Melor affected California and broke several rainfall records.
2012, July 18-20: Associated moisture and clouds from the remnants of Hurricane Fabio generated scattered showers and isolated thunderstorms across the Los Angeles Basin.
2012, September 6-7: Moisture from the remnants of Tropical Storm John brought scattered showers and thunderstorms to California.
2013, August 25-26: Moisture from the remnants of Tropical Storm Ivo caused some thunderstorms and flooding in southern California.
2013, September 3: Moisture from the remnants of Hurricane Kiko fueled a monsoon across the Southwestern United States, producing scattered showers and thunderstorms across the region.
2014, August 26-29: Large swells from Hurricane Marie caused high waves and rip currents.
2014, September 8: The remnants of Hurricane Norbert caused thunderstorms and flooding in Southern California.
2014, September 16-17: Hurricane Odile's outer rainbands brought thunderstorms to parts of Southern California, as a tropical storm. Hurricane Odile also caused damage across central and eastern San Diego County on September 16, 2014, generating high winds and several uncharacteristically powerful thunderstorms in the region. Wind gusts over 23.01 mph (20 knots) reportedly uprooting trees, felled branches, cut power lines, crushed several cars, and flipped at least one airplane at Montgomery Field Airport. Dry lightning generated by a line of severe thunderstorms in one of the rainbands set fire to a palm tree in San Diego and storm force wind gusts within those severe thunderstorms left 6,000 customers without power.
2014, October 6-7: Hurricane Simon's outer rainbands bring scattered thunderstorms and flash floods to parts of Southern California as a tropical storm, and later as a tropical depression, with a brief rain shower in San Diego County on October 7.
2015, June 9-10: A low pressure system containing the remnants of Hurricane Blanca brought showers to Southern California on June 9. Some flooding was reported in Santa Barbara County. On June 10, the low pressure system moved north to the San Francisco Bay Area and brought scattered showers there as well. Many rainfall records were broken.
2015, July 18-20: The remnants of Hurricane Dolores brought scattered showers and thunderstorms throughout Southern California, breaking many rainfall records and causing flooding. One such flash flood caused a bridge to collapse which shut down Interstate 10 between Indio and Blythe, effectively shutting off the primary Phoenix-to-Los-Angeles route. The good news was that the rain helped firefighters contain the North Fire within 3 days.
2015, September 8-15: The remnants of Hurricane Linda brought localized downpours from Santa Barbara to San Diego, California. On September 15, Los Angeles received 2.39 inches of rain, making it one of the wettest September days since records dating back to 1877, second only to 1939.
"Flooding is limited generally to the winter storm season, except in the southern deserts, where summer thunderstorms occasionally produce localized floods.
Because of the size of California, storms and floods seldom occur statewide. The floods of December 1861 to January 1862 were an exception.
[Ref]" Geologic evidence indicates that massive floods, caused by rainfall, have occurred in California every 100 to 200 years. [Ref]
1861, Dec. - Jan 1862: The Great Flood of 1862 also termed the "Noachian Deluge of California". It rained 30 days in succession. The great flood of 1862 primarily affected Oregon, Nevada, and California. It was the largest flood in the recorded history of the area. It occurred when a series of monstrous Pacific storms slammed into the West coast of North America, from Mexico to Canada. "The storms produced the most violent flooding residents had ever seen, before or since." Water covered farmlands and towns. In some places the water reached depths up to 30 feet, completely submerging telegraph poles. The floods drowned people, horses and cattle, and washed away houses, buildings, barns, fences and bridges. Drowning deaths occurred every day on the Feather, Yuba and American rivers. In one tragic account, an entire settlement of Chinese miners was drowned along the Yuba River. [Ref 1][Ref 2][Ref 3]
1884 Feb: San Diego received 25.97 inches (659.64 mm) of rain during the 1883-84 season. In February 1884, 9.05 inches (229.87 mm) fell in San Diego, and by March 10th, the San Diego River was “booming” through Mission Valley. Between February 14 and 20, 5+ inches (127 mm) of rain fell in Spring Valley, CA, (now Valley Spring), flooding damaged crops, livestock and railroads. Flooding also occurred in Temecula Canyon. The Santa Ana River cut a new channel to the sea three miles southeast. [Ref 1][Ref 2]
1895, Jan: A major flood in some portions of California. The recurrence interval is unknown. [Ref 1][Ref 2]
1900 - 1929
1906, March: On March 16-20, Floodwaters reached a maximum depth of four feet in parts of Visalia, CA. During the same month, the flow at the terminus of the Kaweah River was measured at 8,861 cubic feet per second (CFS).
[Ref 1][Ref 2]
1907, March 16: A major flood occurred in some portions of California. The recurrence interval is unknown.[Ref] The flooding of all major rivers in the Sacramento Valley led to changes in how engineers looked at California's flood control system. The system had been based on a Midwestern strategy of confining floodwaters between levees. The idea of using bypasses and overflow weirs, dam-like structures designed to change a river´s flow, had previously been rejected.[Ref]
1916, Jan: During early 1916, heavy rains caused floods throughout Southern California, virtually cutting off San Diego County from the rest of the state for the greater part of a month. Due to the floods 28 people died and about ten million dollars in damages were caused, with the greatest losses occurring in San Diego County, where twenty-two people died mostly in Otay River valley when the Lower Otay Dam failed, releasing the contents of the Lower Otay Reservoir. "One report stated that twenty-five Japanese, including men, women and children, were killed when the dam broke, releasing a wall of water thirty feet high.[Ref 1]" Another estimate was that fifty lives were lost in San Diego County. San Diego residents blamed the floods on Charles Hatfield who was hired by the city of San Diego to create rain. [Ref 1][Ref 2]
1933, December - 1934 January: A major storm occurred in southern California. Los Angeles recorded 7.36 inches (186.944 mm) in 24 hours with a rainfall total of 8.26 inches (209.804 mm) during these storms. The highest rainfall total was reported in Azusa, CA, at 16.29 inches (413.77 mm). Daily totals across the area were 6.21 inches (157.734 mm) at Fullerton, 6.90 (175.26 mm) at Placentia, 5.16 inches (131.06 mm) at Yorba Linda, 4.69 inches (119.126 mm) at Buena Park, 5.04 inches (128.016 mm) at Anaheim, 5.38 inches (136.65 mm) at Orange and 4.81 inches (122.17 mm) at Garden Grove. Walls of water and debris up to 10 feet (3.05 meters) high were noted in some canyon areas. There were 45 deaths in Southern California due to the floods.[Ref]
1937, Feb: 4–7; The highest four-day rainfall totals were recorded at several stations in the Santa Ana Riverbasin during this four day storm. The Riverside, CA north station recorded over 7.9 inches (200 mm) of rain which equaled a 450-year event. [Ref]
1937, Dec: The storm of December 1937 occurred in the higher elevations in the northeast corner of California. [Ref]
1938, Feb-Mar: Also known as the Los Angeles flood of 1825 . On March 2, 1938, with the southern California terrain already saturated, a massive, slow-moving warm front collided with the west trending mountains of the Transverse Range and resulted in near-record rainfall. Rainfall in this mountain area from February 27 to March 4 averaged 22.5 inches (571.5 mm). The greatest rainfall recorded was 32.2 inches (817.88 mm) at an altitude of 8,300 feet. Floods occurred from San Luis Obispo to San Diego and inland as far as the Mojave Desert. Runoff was greatest in the Santa Ana, San Gabriel, and Los Angeles Riverbasins and parts of the Santa Clara Riverbasin. Peak flows in much of the area probably were the greatest since the 1861-62 floods. Eighty-seven (87) lives were lost, and the U.S. Army Corps of Engineers estimated the damage at about $79 million. [Ref 1][Ref 2]
1939, Sept. 25: The 1939 California tropical storm made landfall near Long Beach. Winds were near 80 km/h (50 mph) and rain was near 12 inches (300 mm). The remnants of the hurricane tracked northeastward across northern Baja California into southwest Arizona generating rainfall of up to 7 inches (177.8 mm) on the mountains and deserts.[Ref p 13] Forty-five (45) people were killed in flooding, although these deaths may be partially attributable to a nasty thunderstorm immediately preceding the tropical storm. This is the only known landfall in California by a tropical cyclone at tropical storm strength, during the twentieth century. [Ref]
1950, Nov - Dec: The area from the Kern Riverbasin north to the American River basin, in California, was impacted by flood waters. The recurrence interval was in the 25 to 80 year range. There were 2 deaths and damages were estimated to be $33 million.[Ref]
1955, Dec. 24; More than 3,000 homes were flooded and 12,000 people were evacuation from Yuba City, CA, when a levee failed on the Feather River. There were 38 fatalities, and 95% of Yuba City was inundated with floodwater as much as 12-feet deep. About 382,000 acres of the Sacramento Riverbasin were flooded.[Ref]
1962, Oct: The extratropical remains of Typhoon Freda made landfall in the Pacific Northwest of Canada & the United States on October 12, 1962. Called the Columbus Day storm, the system brought high winds and record breaking rains to the Northwest.[Ref] In California, rains fell from Oakland to Alturas and set a three-day rainfall record for Lake Spaulding of 23.05 inches (585.5 mm). Also in California, one hundred seventy-four (174) gage stations recorded their highest three-day rainfall totals to that time. The storm caused $4 million in damages in California.[Ref]
1964, Dec - Jan. 1965: The floods of December 1964 resulted from meteorological conditions similar to those of the December 1955 floods. An arctic air mass moved into northern California on December 14, 1964, and precipitation on December 18-20 produced large quantities of snow. Beginning on December 20, a storm track 500 miles wide extended from Hawaii to Oregon and northern California. Warm, moist air collided with the arctic air and resulted in turbulent storms that produced unprecedented rainfall on northern California and melted much of the snow from the previous storms. In the Mattole River basin, nearly 50 inches (1270 mm) of rain was reported during December 19-23, with 15 inches (381 mm) observed in 24 hours. The 20-25 inches of rain occurred between December 19 and December 23. The peak discharge of the Salmon River at Somes Bar had a recurrence interval that exceeded 100 years. Several towns along the Eel and Klamath Rivers were totally destroyed. Twenty-four (24) lives were lost in north-coastal California, and flood damage was about $195 million which was 4.5 times the loss in the same region caused by the December 1955 floods. Total damage for the State was estimated by the U.S. Army Corps of Engineers at $239 million. [Ref 1][Ref 2]
1966, Dec: Flooding occurred along the Kern, Tule, and Kaweah River basins. The flooding caused 3 deaths, and flood damage was about $18 million. This event had a greater than 100 year recurrence interval. [Ref]
1969, Jan - Feb: Flooding occurred along the southern and central coast of California and parts of the Mojave Desert. There were 60 deaths, and $400 million in damages. This event had a 30 to 60 year recurrence interval.[Ref]
1976, Sept 9-12: Hurricane Kathleen crossed the Baja California peninsula and moved into California as a tropical storm. Yuma, Arizona reported sustained winds of 57 mph (91 km/h).[Ref] California received record rainfall, with 14.76 in (37.5 cm) falling on the southern slopes of Mount San Gorgonio, and 10.13 in (25.7 cm) accumulated on Mount Laguna. Ocotillo, CA, was flooded with 4 (1.2 m) to 6 feet (1.8 m) of water; [Ref]
subsequently, half the town was destroyed. [Ref] Six people drowned in the mud and waters in the town and two people were initially reported missing, though they were later found by officials. [Ref] Record flood stage was attained at numerous streams near the Coachella Valley. Widespread property damage was recorded on the eastern slopes of the Sierra Nevada as well as the nearby desert. Tropical Storm Kathleen was described as a one-in-160-year event. [Ref] Total damage was $160 million, making Kathleen one of the costliest tropical storms in California's history. [Ref]
Parts of California were declared a disaster area. [Ref]
1977, Aug. 15-17: Hurricane Doreen tracked north northwestward along the west coast of Baja California, dissipating over the coastal waters. Most areas received at least 2 inches (50.8 mm) of rainfall with up to 8 inches (203.2 mm) in the mountains. Heavy rainfall included 4.9 inches (124.46 mm) in Mt. Laguna , 4.5 (114.3 mm) inches in Borrego Palm Canyon, 4.0 inches (101.6 mm) in Palomar Mountain and Lake Henshaw, 3.26 inches (82.8 mm) in Borrego Springs (2.53 inches (64.26 mm) in 6 hours on Aug 16th, a 100 year event). On Aug. 17, 2.06 inches (52.324 mm) fell in Los Angeles, the wettest August day in the history of the city. The estimated damage from this storm totaled $25 million in Southern California and killed four.[Ref]
1980, Jan - Feb: Flooding occurred in central and southern coastal California; the most severe flood was in southern California. [Ref]Between Feb. 13 and 21, six storms hit Southern California. Mount Wilson received 31.69 inches (804.93 mm), 25.56 inches (649.224 mm) fell at Palomar Mountain, 24.34 inches (618.24 mm) in Cuyamaca, 20.65 inches (524.5 mm) in Julian, 18.27 inches (464.06 mm) in Mt. Laguna, 12.88 inches (327.15 mm) in Ramona, and 12.75 inches (323.85 mm) in Los Angeles. Thirty (30) people were killed in widespread floods and mud slides. Post-fire flooding overwhelmed a basin below Harrison Canyon in north San Bernardino four times. [Ref] This was a 10 to 50 year event with damage totaling $350 million [Ref]
1982, Jan: Flooding occurred in the San Francisco Bay Area. Several mudslides occurred in the mountains north of Santa Cruz. These floods had a recurrence interval of 30 years. The California flood resulted in 31 deaths and $75 million in damages.[Ref]
1983; The 1982–1983 "rain year" was the wettest on record in most of north and central California, and was the wettest since 1937–1938 in the few areas where previous records were not surpassed. Levees burst along the Sacramento River and Sierra Nevada, flooding farmland in the Central Valley and several communities including Tehama, and high water also threatened the dikes in the Sacramento–San Joaquin Delta. Significant flooding also occurred on the usually dry Tulare basin north of Bakersfield, where over 28,000 acres (11,331 hectares) were inundated. As much as $850 million of damages were recorded in California, amounting to more than $1.93 billion in 2012 dollars.[Ref]
1986, Feb 11: A vigorous low pressure system drifted east out of the Pacific, creating a pineapple express that lasted through February 24 unleashing unprecedented amounts of rain on northern California and western Nevada. The nine-day storm constituted half of the average annual rainfall for the year over California. Extensive flooding occurred along the Napa and Russian rivers. The Napa River, north of San Francisco, recorded its worst flood to this time while nearby Calistoga recorded 29 inches (736 mm) of rain in 10 days, creating a once-in-a-thousand-year rainfall event. Records for 24 hour rain events were reported in the Central Valley and in the Sierra Nevada. One thousand-year rainfalls were recorded in the Sierras. The heaviest 24-hour rainfall ever recorded in the Central Valley at 17.6 inches (447 mm) occurred on February 17 at Four Trees in the Sierra Nevadabasin. In Sacramento, California,, nearly 10.0 inches (254 mm) of rain fell in an 11-day period. System breaks in the Sacramento riverbasin included disastrous levee breaks in the Olivehurst and Linda area on the Sierra Nevada. Linda, about 40 miles (65 km) north of Sacramento, California,, was devastated after the levee broke on the Yuba's south fork, forcing thousands of residents to evacuate. In the San Joaquin Riverbasin and the Delta, levees breaking along the Mokelumne River caused flooding in the community of Thornton and the inundation of four Delta islands. Lake Tahoe rose 5.9 inches (149.86 mm) as a result of high inflow. The California flood resulted in 13 deaths, 50,000 people were evacuated and there was over $400 million in property damage. Three thousand residents of Linda joined in a class action lawsuit, Paterno v. State of California, which eventually reached the California Supreme Court in 2004. The California high court affirmed the District Court of Appeal's decision that said California was liable for millions of dollars in damages. [Ref 1][Ref 2]
1995: During the 1995 El Niño winter, over 100 reporting stations recorded their greatest 1-day rainfalls in that station's history. The major brunt of the January storms hit the Sacramento riverbasin and resulted in small stream flooding primarily due to storm drainage system failures, though flooding affected nearly every part of the state. On March 12th, the Salinas River exceeded its previous measured record crest by more than 4.3 feet (1.3 meters), which was within 11.8 to 23.62 inches (30-60 cm) of the reputed crest of the legendary 1862 flood. Floods on the Pajaro and Salinas Rivers on March 12th were so severe that they cut off access to the Monterey Peninsula. The Napa River set a new peak record, and the Russian and Pajaro rivers approached their record peaks. More than 70% of California’s counties were declared disaster areas. More than thirty people were killed and 5 were missing. The flood cost $1.8 billion.[Ref 1][Ref 2]
1997, January 1-3: Widespread flooding of streams, creeks and rivers caused extensive damage. The hardest hit towns were Klamath and Stafford. Klamath was flooded by the Klamath River which crested 11.22 feet above flood stage. Stafford was virtually wiped out by a mudslide. Other major rivers that flooded and their crests were: the Eel River near Scotia (3.97 feet above flood stage), Eel River at Fernbridge (5.22 feet above flood stage), Eel River at Miranda (0.64 feet above flood stage), Mad River at Arcata (3.46 above flood stage) and the Van Duzen River near Bridgeville (0.91 above flood stage). Numerous road closures occurred due to flooding and mudslides. The Northwest Pacific Railway was closed due to extensive damage to sections of track. There was $30.3 Million in property damages.[Ref]
1997, Sept. 3-14, Hurricane Linda was at one point forecast to make landfall in southern California. Instead, it moved out to sea, although large waves caused by Linda did wash five people off a jetty in Newport Beach. Linda's outer rain bands generated thunderstorms over southern California causing flash floods in some regions. Hurricane Linda became the strongest storm recorded in the eastern Pacific with winds estimated at 180 mph and gusts to 218 mph. Disastrous flooding and debris flows at Forest Falls caused $3.2 million damage, destroyed 2 houses and damaged 77 others. The flooding moved car-size boulders and caused a wall of mud 150 feet wide and 15 feet tall. Flooding damage also occurred at Oak Glen.[Ref]
1997, Nov. 26-27: A strong Pacific storm brought heavy rain, thunderstorms and snow to Southern California. With this storm, snow levels dropped to around 5000 feet. Snow accumulations up to 6 inches were reported in the mountains. At lower elevations, heavy rain and small hail fell. Rainfall totals ranged from 0.50 to 1.50 inches across the coast with up to 4.00 inches in the mountains. The heavy rain produced numerous street flooding. In Alhambra, 5 high school students were swept down a wash by storm runoff. Three students died while two others survived.[Ref]
1998, April 1: Between March 28 to April 1, 1998, flooding was experienced by the Tulare County communities of Lindsay, Strathmore, and Tonyville. Flooding from locally heavy and persistent winter rains provided excessive runoff for Lewis and Frazier Creeks causing damage to these communities at the interface of the Southern San Joaquin Valley and Southern Sierra Nevada foothills. Lewis Creek jumped out of its banks Wednesday morning, April 1, 1998, impacting and damaging about 32 homes around the creek in northeast Lindsay. Unofficial reports totaled 5.7 inches (144.78 mm) of rain in the week prior to the flooding. There was $262,000 in property damages and $540,000 damages done to crops.[Ref]
2002, December 12: Almost 2 inches (50.8 mm) of rain fell in a two hour period, causing low lying roads and most creeks to flood. In Carlsbad, California, 5 women tried to cross a flooded bridge in a car, which stalled midway then floated downstream and overturned. Two women escaped, the other three drowned. Mudslides closed roads in Fallbrook and Lakeside. The Pacific Coast Highway was flooded in Huntington Beach for three hours. Many roads along the south slopes and foothills of the San Bernardino Mountains were closed for most of the afternoon and evening due to flooding and mudslides. In Riverside County, the worst flooding of roads occurred between Murrieta and Sun City. Property damages totaled $860,000.[Ref]
2006, January 1: On December 31, 2005, severe Flooding occurred as the Napa River exceeded flood stage at both St. Helena and in the City of Napa. Major flooding continued into the early hours of January 1st, before the Napa River finally fell below flood stage and the water receded. Flooding was severe in Downtown Napa from the Napa Creek and the City and Parks Department was hit with $6 million in damage alone. The City of Napa had 600 homes with moderate damage, 150 damaged businesses with costs of at least $70 million. Total damages were $115 Million to property and $32.5 million to crops.[Ref]
2010, December 19-22: A large Pacific plume of moisture ahead of an advancing trough of low pressure brought heavy rain and periods of serious flooding for nearly a week. The plume of moisture responsible was a form of an Atmospheric River. The mountain areas, particularly the San Bernardino range, experienced record large rainfall totals and many areas of flash flooding, debris flows and mud slides. Most rivers in the county warning area reached flood stage. San Bernardino County was the hardest hit county in California in terms of amount of damage due to the heavy rain at the end of December. County officials put the total damage amount (including public and private property of all types and labor to repair damage) at approximately $97 million. Both state and federal money was available to help those affected. Highway 395 at Highway 18 completely flooded with several stalled vehicles. Eastbound Highway 138 just west of Los Angeles County line had mud, debris and water across all lanes. Highway 18, west of Sheep Creek road, was closed, as well as Koala Road between Rancho and El Mirage, due to flooding. PresidentObama proclaimed a Federal disaster declaration for 10 counties in California.[Ref]
2014: August 25-28: Large swells from Hurricane Marie caused high waves and rip currents.[Ref] A large southerly swell around 10 feet, generated by Hurricane Marie, moved through the coastal waters from the 25th through the 28th. This swell resulted in very large surf and dangerous rip currents during this time. Coastal flooding due to the high surf was observed at Seal Beach on the 26th, and reached into some homes, specifically along East Seal Way, where many homes experienced a few inches to 1 foot of water rushing into them after 12 to 14 foot waves cleared the 2 and a half foot protective sea wall. Surf heights from 15 to 18 feet were reported near Newport Beach and northward to Huntington Beach. "The Wedge" at Newport Beach had sets of waves 25 to 30 feet high. [Ref]
2017, February 12-13: Heavy rain brought widespread flooding of small streams and rivers, with some flooding of main stem rivers. Wet conditions from previous storms brought saturated ground and elevated reservoirs, with flood control releases. Reduced releases at Oroville Dam resulted in the use of the emergency spillway for the first time in the dam's history. A portion of the emergency spillway began to show signs of failure which resulted in NWS Sacramento to issue a flash flood warning for potential dam failure and the Oroville Sheriff to issue mandatory large scale evacuations. The emergency spillway was utilized because the main spillway had damage that required reduced flows through it. Several levee breaks also brought local evacuations. There was also mountain snow many feet deep, and damaging winds, with numerous trees down on roads, vehicles, and homes. Many roads, including major highways such as Interstate 80, were shut down due to mudslides, heavy snow, flooding, washouts or avalanche suppression. Other significant impacts included numerous accidents due to slippery roads. A mass evacuation of over 180,000 people located downstream of Oroville Dam was ordered for a possible flash flood, due to the projected near failure of the emergency spillway. The emergency spillway was used when the main spillway was discovered to have suffered severe erosion during releases back on and around February 7th. Releases from Lake Oroville had been increased due to rising lake levels due to inflow from heavy rains. A Presidential disaster declaration, made by PresidentTrump, provided $274 million for emergency response costs from Feb. 7 though the end of May. The money targeted stabilizing the emergency and main spillways, as well as debris removal and work on the downed Hyatt Power plant. A bid for long term repairs to the spillway was accepted at $275 million. Together, these total $549 million, though final costs could be much higher.[Ref]
1996, Dec 22: A cold front sweeping through the San Bernardino and Riverside Mountains generated strong winds and heavy, wet snow in elevations above 6000 feet. Snow began falling during the early morning hours of the 22nd, and increased in intensity, along with the winds, until blizzard conditions were reported shortly after 7:00 AM. In the Big Bear Valley, 40 to 50 mph winds combined with heavy snow to snap trees and power lines, and cause severe visibility restrictions for several hours. By the early afternoon, the storm had diminished, leaving up to one half foot of snow in some areas. [Ref]
1997, Jan. 7-18: Persistent northerly flow and low pressure aloft along the west coast, resulted in a prolonged period of cold and snow for the San Diego Mountains. Up to 18 inches of snow was reported over the higher elevations of the Laguna Mountains, with temperatures dipping into the upper teens and twenties at night. Undocumented immigrants were caught unprepared for the harsh conditions, resulting in a rash of fatalities due to hypothermia. One man died on the seventh, while clinging to a tree in the Tijuana River. Another was found on the Campo Indian Reservation on the tenth. Four more bodies were recovered near Pine Valley on the thirteenth and fourteenth. Elsewhere, a women in her late
twenties died in rural Campo, and a 21 year old man died near Jamul. On January 16, four more undocumented immigrants died of exposure crossing the Laguna Mountains. Finally, on the seventeenth and eighteenth, a young male body was found in an open area near Campo and another was recovered near Potrero.[Ref]
2000, March 5-6: A winter storm started out on the evening of Saturday, March 4 with heavy wet snow at the higher elevations and heavy rain and flooding at the lower elevations. Sustained 40 knot winds overnight caused heavy surf and several boats to lose their anchorage. On Sunday, March 5, strong winds continued to cause damage to trees and power lines. Participants in outdoor athletic events Sunday morning, March 5, developed hypothermia. Later outdoor events were cancelled. As reinforcing cold air arrived Sunday night, snow began at dramatically lower elevations, trapping at least 30 people in the wilderness areas of the San Diego Mountains, closing highways and freeways with seven inches of snow in the passes. Three people died and another thirteen were hospitalized for hypothermia. At the 6500 foot level, seventeen inches of snow fell in less than 24 hours. Blizzard conditions were reported throughout the Southwest California Mountains. The storm caused an estimate $50,000 in property damage.[Ref]
2001, Feb. 13-14: A winter storm that took two days to cross Southwest California created near blizzard conditions in the mountains, forcing the closure of all roads. In San Bernardino County, the Wrightwood received between 27 and 60 inches of snow. The remainder of the San Bernardino County Mountains received 18 to 31 inches of snow.
