Unseasonably hot temperatures and strong Santa Ana winds will continue Friday in San Diego County, raising the threat of wildfires and prompting power shutoffs for about 19,000 customers in a bid to prevent wildfires.

The National Weather Service issued a red flag warning that will be in effect until 5 p.m. Friday in the mountains and valleys.

Sustained winds of 25 to 35 mph are expected, but gusts could reach 65 mph near mountain ridge tops and 75 mph at Sill Hill. Daytime humidity could drop as low as 5%.

High temperatures Friday could reach 90 degrees near the coast, 98 inland, 99 in the western valleys, 92 near the foothills, 80 in the mountains and 90 in the deserts.

The NWS also issued a high wind warning that will be in effect in the county mountains and valleys until 2 p.m. Friday. Officials warned that damaging winds could blow down trees and power lines, while travel will be especially difficult for high-profile vehicles.

A heat advisory will be in effect until 5 p.m. Friday in coastal areas and the inland valleys.

The strong winds will continue through this afternoon, then begin subsiding, forecasters said.

The predicted Santa Ana winds initially prompted San Diego Gas & Electric to notify roughly 24,000 customers of potential power shutoffs for safety reasons, but as of 7 a.m. Friday that number had increased to just over 47,500.
