SAN DIEGO -- Gusty winds are expected once again Monday in San Diego County amid unseasonably warm weather and potentially record-breaking high temperatures.
A National Weather Service wind advisory for the valleys and the mountains is set to expire at 2 p.m. Sustained wind speeds of 20 to 30 mph are expected there, along with gusts of up to 50 mph in most areas and to 60 mph near the mountain ridge tops.
"Surface high pressure over the Great Basin will bring periods of gusty northeast to east winds near the coastal foothills and below passes and canyons into this afternoon," according to the weather service. "Weaker offshore winds will continue into Tuesday."
Forecasters said the gusty wind may make for difficult driving conditions, especially for motorists in high-profile vehicles. Drivers were urged to use extra caution as blowing dust could lead to visibility being reduced to a mile or less and the wind may be strong enough to send broken tree limbs and other debris into the roadway.
High pressure will also cause daytime temperatures to again soar, forecasters said. A high temperature record of 83 degrees in Chula Vista, set in 1918, was topped by one degree on Sunday, according to the NWS.
"A strong ridge of high pressure over the region, combined with offshore flow, will create very warm conditions across the region for this time of year," according to the weather service. "High temperatures are forecast to be 10 to 20 degrees above normal today and Tuesday. The warmth will continue through the remainder of this week under sunny skies."
High temperatures today were predicted to be 78 to 83 degrees near the coast, 85 to 90 degrees inland, 87 to 92 degrees in the western valleys, 79 to 84 degrees near the foothills, 67 to 76 degrees in the mountains and 79 to 84 degrees in the deserts.
Forecasters said dry conditions with temperatures well above average would extend throughout the work week and into the upcoming weekend.
