A flash flood watch was issued by the National Weather Service this afternoon, as a pacific storm passes through the region.

The warning was issued for San Diego coastal areas and inland valleys after a Pacific storm was seen on weather radar screens forming off the coast, according to the NWS.

Heavy rain, lightning and cold temperatures were expected throughout San Diego County by Saturday evening. Three storm systems were expected to hit land from the west over the next three days.

Soaking rain and thunderstorms were expected to pack a punch this evening, with a chance for water spouts off the coast, according to the NWS.

The stormy weather should taper off by Sunday morning, with another system expected later Sunday and early Monday. Highs in the upper 60s were forecast for the area Saturday, with evening lows expected to be in the upper 40s to 50s.

Rainfall totals could reach a third of an inch this weekend and cause minor urban flooding in some areas, the NWS said.

Remember “Turn Around, Don’t Drown,” says the NWS as a safety reminder to drivers who may encounter flooded roadways.

As shown in the Flash Flood advisory graphic from the NWS, the highest risk areas include San Diego, Oceanside and Newport Beach.
