Scattered showers and isolated thunderstorms were expected in San Diego County today, increasing the risk of flash flooding in coastal, valley and mountain areas, forecasters said.
National Weather Service forecasters estimated that up to an inch of rain is possible today at the coast, 1.5 to 2 inches in the foothills and 2 to 3 inches on coastal mountain slopes.
Although the main front of this week's fourth storm has left the region, a flash flood watch for coastal, valley and mountain areas below 4,500 feet was in effect through this afternoon. The mountains were also under a winter storm warning scheduled to expire at 6 p.m.
Sunny skies are expected this weekend, followed by warmer temperatures and overall fair weather on Monday, said NWS meteorologist Stefanie Sullivan
Forecasters said the rain may return Tuesday and Wednesday, although the rainfall will be considerably lighter than was the case this week.
The surf will remain high along beaches through Sunday night, particularly today into Saturday, when breakers over 20 feet are possible on the outside reefs, according to the NWS.
A coastal flood watch remains in effect until 4 a.m. Saturday and a high surf advisory is in effect until 2 a.m. Monday.
Relentless downpours and powerful winds pounded San Diego County this week, flooding dozens of roads, toppling trees, shutting down schools, delaying trains, canceling airline flights and causing the first weather-related closure at SeaWorld in 12 years.

A motorist tried unsuccessfully to drive the truck across the flooded creek, Schuler said, adding that the vehicle was swept sideways down stream.The driver and a child passenger were able to escape on their own, but the dogs were left behind, according to the battalion chief.
A day earlier, Cal Fire firefighters pulled two people from a vehicle
