High pressure aloft over California combined with offshore flow will bring hot daytime weather to San Diego County later this week, with inland temperatures soaring into the triple digits, forecasters said Wednesday.
The hottest temperatures will occur from mid-morning to late afternoon Friday and Saturday in coastal areas; from late morning to late afternoon Friday through Sunday in the valleys; and from late morning through late afternoon Friday and Saturday in the mountains, according to the National Weather Service.
The agency scheduled a heat advisory for coastal and mountain areas from 11 a.m. Friday to 8 p.m. Saturday and a heat advisory for the valleys from 11 a.m. Friday to 8 p.m. Sunday.
There was no advisory issued for the deserts, though triple-digit heat is also expected there starting Friday.
“Heat can be stressful to animals and humans, making it hard for the body to acclimate and remain hydrated,” according to the weather service. “Without precautions, even healthy adults could experience heat stress and illness.”
The agency encouraged those spending time outside to reschedule strenuous activities to early morning or evening hours, if possible.
For its part, Cal Fire is bracing for the hot weather by assigning an additional air tanker to the Ramona Airport this weekend, according to public- affairs Capt. Kendal Bortisser. In the event of a wildfire, Cal Fire would have a total of three airtankers at the ready to help squash the flames.
Relief from the heat wave is expected early next week but it will be a slow cooling, NWS forecasters said.
