Southern Californians are in for another round of rain and snow starting Wednesday, but precipitation totals are expected to remain low in most areas, creating little disruption.
The system's biggest threat is unpredictable thunderstorms, which could bring heavy rain and flash flooding Wednesday afternoon and evening in some communities along the coast and valleys, according to Rose Schoenfeld, a meteorologist with the National Weather Service. in Oxnard.
“In storms, you could get rainfall up to an inch an hour, a heavy downpour,” Schoenfeld said. That would be isolated to a limited number of areas, he said, but it was unclear exactly where or when the storms would hit.
Widespread showers are expected from Santa Barbara to San Diego as a cold low pressure system arrives from coastal waters off Point Conception early Wednesday and heads southeast over the next 48 hours. Rainfall totals are likely to remain below an inch, with the highest amounts occurring wherever a storm cell forms.
“Rainfall totals will range from a quarter [of an inch] up to 1 inch of rain,” said Mark Moede, a meteorologist with the National Weather Service in San Diego. “One hundred percent of the area is going to see some rain. It's just a question of how much.”
Rainfall amounts still appear to range between 0.25 and 0.75 inches, with local amounts of up to 1 to 2 inches in the foothills and mountains. The highest amounts should occur south of Point Conception. Snow levels could drop locally to 4,000-4,500 feet early Thursday. #CAwx #LARain pic.twitter.com/WHh8SbDWda
