Widespread Power Outages and Severe Weather Grips California as Pineapple Express Brings Chaos

Overview :

California faced a barrage of challenges as the state grappled with heavy rains, strong winds, and flooding, leaving nearly 700,000 residents without power. The onslaught was attributed to the second and more intense atmospheric river event in a week, known as the “Pineapple Express.”

Key Developments :

• Power Outages: Over 693,000 homes and businesses in California experienced power outages as the atmospheric event continued its course through the state, according to Poweroutage.us.
• Flash Flood Warnings: Several areas in Los Angeles County, including Santa Monica, West Hollywood, and Beverly Hills, remained under a flash flood warning until Monday morning, as highlighted by the National Weather Service’s Los Angeles office.
• Wind Impact: The San Francisco Bay Area faced warnings of sustained wind speeds reaching 55 miles per hour, with gusts exceeding 100 mph in certain areas.
• Life-Threatening Flash Flooding: The National Weather Service issued a warning of “life-threatening and damaging flash flooding” anticipated across central and southern California on Monday.
• Sierra Nevada Impact: Parts of the Sierra Nevada mountains were expected to receive up to 4 inches of snow, accompanied by strong winds causing high surf along the state’s coastline.
• School Closures: Due to severe weather conditions, schools in the Santa Barbara Unified district remained closed on Monday. However, classes continued as scheduled in Los Angeles and San Francisco.

Noteworthy Statistics :

Downtown Los Angeles received 4.10 inches of rain on Sunday, marking the city’s third wettest February day since 1877 and the 10th wettest day overall, according to the National Weather Service (NWS).

Background :

The extreme weather conditions were attributed to an atmospheric river, specifically the “Pineapple Express.” These are elongated bands of atmosphere carrying moisture from tropical oceanic regions to colder areas further north, causing intense rainfall and floods. The Pineapple Express originates from tropical regions around Hawaii, delivering moisture across the Pacific to the U.S. West Coast.

Upcoming Impact :

The influence of the atmospheric river is expected to persist until Tuesday. Los Angeles will continue to experience heavy rains on Monday morning before the storm progresses southward to Orange County and San Diego later in the day. Coastal flooding and high surf are expected to remain concerns through Monday evening, with Southern California anticipating heavy to moderate rainfall until Tuesday.
