A heat wave will ramp up Friday and continue through this weekend in San Diego County, bringing scorching temperatures to the deserts in particular.
A high-pressure system moving in from the east will bring scorching heat until Tuesday, when temperatures in inland areas are expected to cool off, according to the National Weather Service. Temperatures in the mountains and deserts will remain hot for another day, then begin dropping on Wednesday.
No monsoonal moisture is expected with the system, but humid conditions could return early next week, forecasters said.
The deserts could see highs of 118 on Sunday and 117 on Monday, while temperatures in inland valley areas are expected to remain in the low 90s throughout the weekend.
High temperatures Friday could reach 88 near the coast and inland, 92 in the western valleys, 101 near the foothills, 99 in the mountains and 116 in the deserts.
NWS officials urged residents to drink plenty of fluids and check up on elderly relatives and neighbors, especially those without air conditioning.
