Southern California will continue to bake under sweltering conditions that are expected to stretch through the Labor Day weekend — with excessive heat warnings Wednesday across all of San Diego County.

“An excessive heat warning has been issued for the entire forecast area from 10 a.m. Tuesday through 8 p.m. Monday,” the National Weather Service office in San Diego said. “Use extreme caution and modify plans appropriately if you plan on being outdoors this holiday weekend.”

The California Independent System Operator, which manages the state’s power grid, warned that it may issue Flex Alerts, which are calls for voluntary power conservation, during the busy hours of 4 p.m. to 9 p.m.

The heat is expected to peak on Wednesday and Thursday, with temperatures as much as 10 degrees higher on Wednesday than on Tuesday in some areas.

The forecast for San Diego County calls for highs in the mid 80s near the coast, lower 90s inland, upper 90s in the western valleys, 103 near the foothills, 94 to 100 in the mountains and 112 to 117 in the deserts.

The weather service expects only modest relief through the holiday weekend — if at all.

“The potential for Sunday and Monday being the hottest is still there, especially over the coasts and valleys,” according to the agency. “Valley temperatures will approach all-time records.”

Overnight lows will not offer much relief, staying in the 70s and even in the low 80s in some of the hotter areas.

Forecasters urged residents to be aware of the signs of heat stroke and to take precautions.

“Take extra precautions if you work or spend time outside,” the weather service advised. “When possible reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear lightweight and loose fitting clothing when possible.”
