More rain pounding San Diego

SAN DIEGO (CNS) – Another blast of cold, wet winter weather has arrived in San Diego County Wednesday, ushering in the possibly of some snow in the mountains, meteorologists said.

Wednesday's storm will be a follow-up to last week's torrential rains and will arrive out of the northwest early this morning, according to the National Weather Service.

Rainfall totals from the blustery system, which will weaken by this afternoon before moving out of the region tonight, will range from as much as two-thirds of an inch along the coast and in the inland valleys, near an inch on west-facing slopes and less than a quarter inch in the deserts, the Weather Service reported.

The North County will get more of the moisture than communities to the south, according to the NWS. The highest mountain peaks, meanwhile, may get an inch or two of snow.

Due to heavily saturated ground throughout the area, runoff will likely be immediate and fast-moving, possibly causing more of the types of flooding, mud-slide and debris-flow problems wreaked by prolonged downpours earlier this month, the NWS advised.

The storm also will generate stiff winds, especially in the mountains and high deserts, where gusts may exceed 65 mph and reduce visibility to near zero at times while possibly downing trees and power lines, according to the weather service.

A wind advisory for coastal and valley areas was scheduled to in effect from 10 a.m. to 4 a.m. Thursday. Meanwhile, a high wind warning already in effect for the mountains was also scheduled to expire early Thursday.

The Weather Service also issued a small craft advisory from 10 a.m. to 4 a.m. Thursday.

On Thursday and Friday, temperatures in the county will likely drop 10 or 20 degrees below seasonal averages, causing widespread frost in low-lying inland communities.
