Warmer weather with clear skies over San Diego County Sunday was predicted to give way to windy and cooler conditions on Monday as a cold trough deepens, the National Weather Service said.

Damaging wind gusts were possible over the mountains on Monday, with gale force winds and rough seas into the coastal waters.

A wind advisory was issued by the weather service from 1 p.m. Monday to 3 a.m. Tuesday for San Diego County deserts and mountains. The mountains could get winds of 20-30 mph with gusts of 50-60 mph in more wind-prone areas.


The cold front should race past Monday evening and the winds were expected to shift north-northeast Monday night. The strong winds were predicted to be confined mostly to the mountains.

An incoming west-northwest swell of 6-10 feet may generate elevated surf at San Diego beaches Monday and Tuesday. Surf of 3-6 feet was expected, with local sets to seven feet possible late Monday night.

A stronger round of northwest winds was expected Monday and Tuesday, with northwest winds of 25-30 knots and gusts of 35-40 knots, strongest later Monday, the NWS said. Combined seas were predicted to reach 10 to around 12 feet across the outer waters.

After a cool day Tuesday, temperatures start trending upward Wednesday and Thursday as high pressure starts to rebuild over the Southwest.

Friday was forecast to be warm with coastal highs in the 70s, valley highs in the 80s, mountain highs in the 50s and 60s, high desert highs in the 70s and the low deserts in the upper 80s.


Because of high winds that are expected to make travel via high-profile vehicles such as school buses inadvisable, the Mountain Empire Unified School District has announced it will not hold classes Monday.

The district encompasses most of southeastern San Diego County, including Campo, Pine Valley, Descanso, Potrero and Boulevard.

The San Diego County Office of Education will post real-time updates on the situation at @SanDiegoCOE on Twitter.
