The weather will turn windy and cooler on Monday, with dangerous gusts over the mountains and deserts, as a cold front moves in, the National Weather Service said.

“A cool and blustery weather system will move into Southern California today, bringing strong winds to all areas and a small chance of showers mainly to the mountains,” the weather service said.

Damaging wind gusts were possible over the mountains on Monday, with gale-force winds and rough seas in 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.

High temperatures Monday were forecast to be around 68 along the coast, 65 to 70 inland, 59 to 67 in the mountains and 82 to 87 in the deserts.

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

In the outer coastal waters, northwest winds were expected to increase Monday and Tuesday, reaching 25-30 knots with gusts of 35-40 knots, the weather service said. Combined seas were predicted to reach 10 to around 12 feet across the outer waters.

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