A fast-moving low-pressure system promises light rain and mountain snow across the San Diego region beginning Sunday afternoon and continuing into Monday.
Rainfall is expected to total .1 to .5 inches along the coast and in the valleys, but will reach .5 to 1 inch in the mountains, according to the National Weather Service office in San Diego. The snow level will drop to 4,000 feet.
“A low pressure trough will swing across Southern California on Sunday, accompanied by periods of light rain at lower elevations, and snow and strong southwest to west winds in the mountains,” the weather service said.
Monday and Tuesday are expected to be dry, but will be followed by an “atmospheric river’ beginning late Wednesday.
