A high surf advisory was issued from 11 a.m. Monday to 3 a.m. Wednesday for San Diego County coastal areas.

A high rip current risk was expected at all beaches Monday through early Wednesday. A long period west swell, and a long period south swell may result in surf of 6-8 feet, with sets up to 10 feet possible in southern San Diego County, forecasters said.

Tuesday was predicted to be a dry, cool day, followed by warmer weather and weak offshore flow in the second half of this week.

Daytime highs should increase to above seasonal norms with some highs in the 90s in the valleys and especially lower deserts by Thursday, with a slight cooling trend over the weekend.

The storm system was expected to bring southwest and northwest winds with gusts of 20-25 knots in the outer waters and closer to 20 knots across the inner waters Monday afternoon and Tuesday. Combined seas of 6-10 feet were expected, highest in the outer waters.
