Strong, hot Santa Ana winds buffeted the valleys and mountains of San Diego County for the second consecutive day Wednesday.

Temperatures in the 90s were forecast for much of coastal and inland San Diego. The National Weather Service said the hot weather will continue through Friday, with many temperature records likely to be broken.

The high winds knocked out power to 662 San Diego Gas & Electric customers in the far eastern reaches of San Diego County early Wednesday, according to the utility.

The outage struck at 1:18 a.m. and affected the areas of Descanso, Cuyamaca, Viejas, Boulder Creek, Pine Valley and Mount Laguna, SDG&E reported on its website. By 4 a.m., power was restored to all but nine customers.

A high wind warning for valley and mountains areas is in effect through 5 p.m. Thursday.

“Sustained winds during this time will range from 20 to 40 miles per hour with gusts of 40 to 60 mph over the foothills and valleys,” the NWS said, adding that peak winds of 60 to 80 mph are likely in a few of the wind-prone mountain and foothill areas.

There will be a brief lull in the winds Wednesday evening before a third and slightly weaker surge of gusty winds arrives late Wednesday night and continues into early Thursday, according to the weather service.
