The NWS issued the alert on Friday morning at 9:29 a.m.
Red Flag Warnings detail critical weather conditions that put specific areas at a higher risk for fire.
According to the warning put out by the NWS, an offshore wind gust of 40 to 50 mph will sweep through the mountains on Friday night. The strongest winds are predicted for early Saturday morning and Saturday night, with a possibility of 60 mph gusts.
This, coupled with weather in the 90s and low humidity, present a high fire risk.
