Temperatures in San Diego County will rise into the mid-90s Friday while triple-digits temperatures are expected in desert areas, but the heat wave is expected to end on Sunday, according to the National Weather Service.
A high pressure air mass drifting from inland areas into coastal areas will keep temperatures hot through Saturday, then high temperatures will drop on Sunday and Monday, forecasters said.
The NWS issued a heat advisory that will be in effect from 11 a.m. Friday to 6 p.m. Saturday in the inland valleys.
NWS officials advised that those who work outdoors should avoid the midday sun, wear light, loose-fitting clothing and drink plenty of water.
High temperatures Friday could reach 83 degrees near the coast, 92 inland, 95 in the western valleys, 85 in the mountains and 103 in the deserts.
Winds out of the east and northeast will be moderate today, with gusts expected to top out at 30 mph near the county mountains this morning.
Highs in the western valleys will drop to the high-80s on Sunday, then the mid-80s on Monday, forecasters said. High temperatures in the deserts will remain around 100 through at least Thursday next week.
