SAN DIEGO - The second in a series of winter storms is expected to batter San Diego County Friday, bringing downpours that could again lead to flooding, plus heavy mountain snow, potentially damaging winds and thunderstorms.
The storms prompted the National Weather Service to issue a slew of warnings and advisories for various parts of the county.
A winter storm warning for the mountains will remain in effect from until 6 a.m. Saturday. Elevations as low as 5,000 feet may see 3 to 7 inches of snow, 6 to 12 inches could accumulate between 5,500 and 6,000 feet, 1 to 1 1/2 feet could blanket higher peaks.
Heavy rainfall with amounts that could exceed an inch per hour at times and thunderstorms in some areas may lead to flooding. A flash flood watch for areas other than the deserts will run from 7 a.m. through this evening.

The storms will also lead to problems at the beaches, such as strong rip currents and waves big enough to sweep beachgoers off jetties and rocks or damage piers. Surf of 8 to 12 feet with sets to 16 feet is expected through Saturday, then will lower somewhat over the weekend before ramping back up to 8 to 12 feet again on Monday, according to the NWS.
A high surf warning will remain in effect through 10 p.m. Tuesday.
A break between storms is expected Saturday, but the next and possibly strongest in the series of storms will arrive Sunday.
Forecasters said the third storm would bring rain to most areas and snow only on the highest mountain during the day Sunday. The snow level is expected to fall to as low as 4,000 feet Sunday night through Monday.
