As Southern California enters the spring season, it is bracing for another atmospheric river. The latest storm marks the 12th, including those that hit the region during the winter. The National Weather Service (NWS) warns of a soggy week ahead, with many hours of light to moderate steady rain. They also advise that residents should expect plenty of water, rocks, mud on roads, and minor and urban creek flooding.
According to the NWS, early predictions for the storm Tuesday through Wednesday are between one to two inches of rain, with isolated amounts of up to three inches in the mountains. Tuesday is looking to be the main day for precipitation, with light rain beginning on Monday and scattered showers on Wednesday.
The low snow levels are expected to start at about 5,000 feet, falling quickly to 4,000 feet on Tuesday afternoon and then to 3,000 feet Tuesday evening and Wednesday morning. This could cause accumulating snow in the major mountain passes, with the NWS stating that two inches of snow are possible with this system. Above resort level, 1-2 feet of snow is expected, and light snow up to 2″ is possible over the Tejon Pass, likely impacting travel.
Strong and possibly damaging winds are also expected on Tuesday, with the NWS warning of potential widespread “gale force winds and hazardous seas.” Boaters were advised to heed all precautions. Temperatures are also expected to drop in the region, with daytime highs dropping into the low 60s on Monday and the mid-50s on Tuesday and Wednesday, according to the NWS.
As California prepares for its 12th atmospheric river, officials advise residents to stay informed and take precautions as necessary.
