A National Weather Service heat advisory took effect on Tuesday and is scheduled expire at 7 p.m. Sunday.
Forecasters said temperatures would be 7 to 15 degrees above seasonal averages. Highs of 111 to 116 degrees were forecast for the deserts today and Saturday. However, the weather service predicted temperatures could range from 110 to 120 degrees in Borrego Springs, Ocotillo Wells, Canebrake and in the Anza-Borrego Desert.
“Strong pressure aloft will peak over the southwest this weekend and bring very hot days in the lower deserts,'' according to the weather service. “High temperatures will range from 110 to 120 each day.''
Residents and those working in desert areas were advised to protect themselves from heat-related illnesses and to be aware of the signs and symptoms of heat exhaustion and heat stroke. Anyone overcome by heat should be moved to a cool, shady area and 911 should be called, authorities said.
“Take extra precautions if you work or spend time outside,'' according to the NWS. “When possible, reschedule strenuous activities to early morning or evening.”
Forecasters said gradual cooling was expected to begin next week as the high pressure drifts off to the east.
