Heat Advisories In Effect As Heat Wave Hits San Diego County

Heat advisories took effect in San Diego County Friday morning as a heat wave expected to last at least three days hit the region.

"A ridge over the Southwest and weak offshore flow will bring above average-temperatures over the weekend," according to the National Weather Service. "The most anomalous temperatures will occur from the foothills of the mountains westward. A downward trend in temperatures will begin by Monday and continue into early next week."

The agency scheduled a heat advisory for coastal and mountain areas from 11 a.m. Friday to 8 p.m. Saturday, saying highs Friday would be in the 90s to around 100 just a few miles inland from the coast. The foothills and lower mountain elevations will also be very hot, with highs from 92 to 102, the agency said.


Valley areas also were subject to a heat advisory Friday. The weather service scheduled a heat advisory the valleys from 11 a.m. Friday to 8 p.m. Sunday, saying highs from 95 to 105 were likely Friday.

"Consecutive days of hot weather will increase the heat stress on animals and humans, making it hard for the body to keep cool," the weather service said. "Without precautions, even healthy adults could experience heat stress and illness."

Ways to avoid such illnesses include rescheduling strenuous outdoor activities to early morning and evening hours; wearing light, loose fitting clothing; taking frequent breaks in shaded or air-conditioned areas; and drinking plenty of water.

Also Friday, the weather service issued a beach hazardous statement for local beach areas from 5 a.m. Friday through late Sunday night, saying elevated surf and strong rip currents were likely. The highest surf — 3- to 5-foot waves with set to 6 feet — was expected on south and southwest facing beaches.

Beach-goers were encouraged to obey all posted warning signs and flags, and to talk to lifeguards before swimming.
