Up to an additional inch of rainfall was possible in the region through Monday evening, particularly in the northern areas and coastal slopes, accompanied by temperatures dipping into the upper 30s in the valleys, the National Weather Service said.
A winter storm warning issued Monday morning by the NWS remains in effect until 4 a.m. Tuesday for San Diego County mountains above 4,500 feet. Elevations above 5,000 feet can expect eight to 14 inches of snow, while those above 6,500 feet may get up to 20 inches, according to the NWS.
