Шаблон:Short description Шаблон:Infobox flood In early February 2024, two atmospheric rivers would bring extensive flooding, intense winds, and power outages to portions of California. The storms would cause record-breaking rainfall totals to be observed in multiple areas, as well as the declaration of states of emergency in multiple counties in Southern California. Wind gusts of hurricane force would be observed in San Francisco, along with wind gusts reaching over 100 miles per hour (160 km/h) in the Sierra Nevada mountains. Widespread landslides would occur as a result of the storms, as well as multiple rivers overflowing due to the excessive rainfall. Meteorologist Dr. Reed Timmer stated that "Biblical flooding" was possible throughout California during the atmospheric river.

From February 1 to February 2, 2024, California experienced the impact of the first Pineapple Express storm caused by the atmospheric river, which subsequently traversed the United States and settled over the I-25 corridor in Colorado.Шаблон:Citation needed

Another storm struck on February 4, with the National Weather Service categorizing it as "potentially life-threatening", and forcing Los Angeles into a state of emergency. Seven additional counties declared a state of emergency: Orange County, San Bernardino County, Riverside County, San Diego County, San Luis Obispo County, Santa Barbara County, and Ventura County. The rain was expected to last for days, with some parts of California expected to receive record amounts of rain.

Various news outlets projected that Los Angeles might witness an accumulation of rainfall equivalent to six months' worth between February 3 and February 5. Simultaneously, the Sierra Nevada mountains were anticipated to receive 1 to 3 feet (30 to 91 cm) of snow, while higher elevations, such as Mammoth Lakes, CA, could potentially experience over 4 feet (120 cm) of snow. The NASCAR exhibition race at the Los Angeles Memorial Coliseum was moved forward one day to February 3 from the scheduled February 4 race in anticipation on the rainstorm. Additionally, portions of the San Bernardino Mountains' foothills are expected to receive substantial rainfall, with estimates ranging from 10 to 12 inches (250 to 300 mm). One man was killed on February 4 after a tree struck him due to the winds.

February 5

Several Malibu, California schools were closed due to inaccessibility because of severe weather causing road closures. Power outages caused by the storms left approximately 850,000 people without power. Fallen trees blocked roads and cut power lines in multiple locations. Wind gusts up to 162 mph (260 km/h) occurred at various high elevation locations, including the Sierra Nevada mountains and Lagunitas Forest. As of February 5, at least three people had died from falling trees.

February 6

Heavy rainfall caused more than 300 landslides and severe flash flooding throughout the state. San Diego received record rainfall for California at higher elevations causing floods and prompting road closures. A tornado warning would be issued for portions of San Diego County by the National Weather Service due to a severe thunderstorm produced by the storm complex, although no damage would be caused.

February 7

Following Шаблон:Convert of rain in Death Valley in 72 hours, California State Route 190 was closed and the park experienced a setback in the recovery from Hurricane Hilary. Two tornadoes were confirmed to touch down in San Luis Obispo county.

Impact

The city of Los Angeles had been incorporating elements of a sponge city design in order to retain the rainwater. Over the course of February 4 to 7 the city captured 8.6 billion gallons of water, equivalent to the yearly needs of 106,000 homes.
