California Hit by Heavy Rain and Snow as Atmospheric Rivers Cause Flooding
California is experiencing heavy rain and snow as powerful atmospheric rivers hit the state. The storm initially struck the San Francisco Bay Area on Wednesday before moving to the southern and eastern parts of the state. The downpours resulted in flooding, halting cable car service and snarling the morning commute in Southern California.
The storms are fueled by atmospheric rivers, long bands of moisture that form over the Pacific. These rivers interact with the West Coast topography, leading to heavy rain along the coastal ranges and inland through the Sierras. The current storm, known as the “Pineapple Express” due to its connection to Hawaii, will be followed by an even stronger storm on Sunday.
Last winter, California experienced similar atmospheric rivers that caused extensive flooding, large waves, and heavy snowfall. This week’s storms pose a significant threat to the safety of Californians. The California Governor’s Office of Emergency Services has activated its operations center and positioned personnel and equipment in areas at risk.
The impact of the storms is widespread, ranging from the state’s border with Oregon to San Diego and from the coast into the mountains. Flash flooding has already affected southern Los Angeles County, with vehicles plowing through water on freeways and underpasses being inundated. Seal Beach and Costa Mesa have also experienced flooding, with rescue teams conducting swift-water rescues.
In terms of snowfall, the Mammoth Mountain ski resort in the Sierra Nevada reported 12 to 14 inches of snow overnight. This is good news for a state that heavily relies on the Sierra snowpack for water supply. Earlier this week, state officials reported that the snowpack was far below normal.
A winter storm warning is in effect for a nearly 300-mile stretch of the Sierra, with heavy snowfall and strong winds expected. The second atmospheric river, anticipated to arrive on Saturday, is predicted to be the largest storm of the season. It is expected to stall over Point Conception in Santa Barbara County, producing continuous rain for 24 to 36 hours or more.
Following this, Southern California is likely to experience significant rain and snowfall from Monday through Wednesday, which could lead to mudslides and dangerous flooding. The situation is being closely monitored by authorities to ensure the safety of residents.
As Californians brace themselves for the impact of these powerful storms, it is crucial to stay updated on weather forecasts and heed any evacuation orders or warnings issued by local authorities. Preparation and caution are key to minimizing the potential risks associated with severe weather events like these atmospheric rivers.
