Heat Wave Begins; 100º Wednesday Expected

A heat wave will strike San Diego County on Wednesday, when temperatures will climb into the 90s at the beaches and the 100s in inland areas, forecasters said.

Offshore flow and an unusually strong upper level high pressure centered over the coast will produce “very warm temperatures” Wednesday and Thursday, according to a National Weather Service advisory.

“The hottest day at the beaches will be today,'' it said Wednesday, and inland areas, the valleys, the mountains and the deserts will experience their hottest temperatures Thursday.

Temperatures were expected to cool throughout the region Friday, but still be running 5 to 10 degrees above normal for this time of year.

“Residents not used to this heat should be extra cautious with outdoor activities,'' according to a Weather Service advisory, adding that those without air conditioning should be checked on.
