SAN DIEGO — A low-pressure storm system that visited in most parts of San Diego County today set rainfall records in at least four San Diego County locations, according to the National Weather Service.

The system moving to the southeast hit hardest from about 8 a.m. to early afternoon.

It left .57 of an inch of rain at Palomar Mountain; .23 in Vista; .13 in Oceanside Harbor; and .10 in Ramona, all records for May 16.

The storm was expected to produce some isolated showers until late tonight, NWS meteorologist Miguel Miller said.

The weather service said that by the time the storm leaves, rainfall totals could reach up to two-tenths of an inch in coastal and inland-valley areas and up to eight-tenths of an inch in mountain regions, meaning a possibility of more record precipitation.

Gusty winds could cause hazardous driving conditions in the mountains and deserts.

The NWS issued a wind advisory that will last until 11 a.m. Friday for those two areas.

The winds blowing to the west are expected to range from 20 to 40 mph, with gusts of 65 mph possible along desert mountain slopes, forecasters said.

Powerful winds could whip up sand and dust and create potentially hazardous driving conditions, especially for high-profile vehicles, the NWS warned.

Another low-pressure system is expected to arrive late Sunday morning and could bring a chance of rain through Monday morning, Miller said.
