SAN DIEGO — In addition to the election fallout, San Diego County residents will be faced Wednesday with gusty Santa Ana winds, temperatures up to 20 degrees above average, an increased risk of wildfires and big waves at the beaches.

A National Weather Service red flag warning, issued for hot weather, gusty winds and low humidities that may lead to “critical fire weather conditions” in the inland valleys and near the foothills, will take effect at 10 a.m. and extend until 4 p.m. Thursday.

On Tuesday, high temperatures of 93 degrees in El Cajon and 91 in Ramona matched local records for the date, both set in 2006.

High temperatures Wednesday are expected to range from 84 to 89 degrees along the coast, 89 to 94 inland, 92 to 97 in the western valleys, 73 to 83 in the mountains and 85 to 90 near the foothills and in the deserts. Slightly lower temperatures are expected Thursday.

Forecasters said humidity levels would dip below 15 percent as the drying winds ramp up. The critical wildfire potential in the valleys is expected to continue Thursday, according to the weather service.

A wind advisory warning of winds of 15 to 25 miles per hour with gusts to 50 mph in the valleys will remain in effect until 1 p.m. Thursday. The strongest winds are expected to blow across the far inland valleys near the coastal foothills.

A high surf advisory prompted by 5- to 9- foot surf with sets to 11 feet are expected south of Del Mar will remain in effect from 7 a.m. to 5 p.m. Thursday. Big waves and strong rip currents can create hazardous swimming conditions and up the risk for drowning.
