SAN DIEGO — Another late-autumn storm will bring more downpours and flash-flooding risks to the San Diego area toward the end of the week.
The unsettled front moving into the area out of the Pacific Northwest is expected to start delivering steady rainfall starting late Thursday night and continuing for about 24 hours, according to the National Weather Service.
Depending on the localized intensity of the showers, the influx of moisture could cause flooding and landslide risks in some areas, particularly in denuded spots such as the burn area of last spring’s Cocos Fire near San Marcos, the NWS cautioned.
“The flash-flooding potential all depends on if a certain area gets a certain amount of rain in a certain amount of time,” meteorologist Jimmy Taeger said.
Rainfall rates could reach rates up to half an inch per hour, with the heaviest cloudbursts coming Friday morning. Expected precipitation totals, however — 0.6 to 1.25 inches along the coast and in the valleys, 1 to 3 inches in the mountains and less than half an inch in the deserts — will be lower than those seen in the county during last week’s storm, the federal agency predicted.
The region’s highest peaks likely will get a few inches of snowfall, according to the weather service.
The weekend should bring a return of sunny skies and pleasant temperatures, Taeger said.
