County; the Los Padres National Forest in Ventura County; L.A. County’s San Fernando, Santa Clarita and San Gabriel valleys; and the L.A. coastal zone, which includes beach cities, metropolitan Los Angeles, downtown L.A. and the Hollywood Hills.

Wind gusts as strong as 58-miles-per hour are expected in the San Gabriel and Santa Monica mountains, according to the National Weather Services. Such windy conditions will make driving difficult, especially for motorists in high-profile vehicles, and could bring down trees and power lines.

At the same time, summertime temperatures were expected to remain abnormally high — around 18 degrees higher than normal in some areas — possibly reaching 85 in downtown L.A. and 90 in Yorba Linda.
