Go get flashlight batteries if you don’t have any! From the National Weather Service:
A strong Santa Ana wind event is expected between late tonight and Friday. Strong high pressure developing over the Great Basin will increase north to northeast winds across the area through Thursday morning peaking in intensity late Thursday morning through mid afternoon Thursday.
The combination of strong offshore flow and good upper-level wind support could produce damaging wind gusts in excess of 60 mph across portions of Los Angeles and Ventura Counties. Impacts include downed trees and power lines as well as the potential for high fire danger with rapid fire growth due to the strong offshore winds and low humidity values. Driving conditions will be hazardous for high profile vehicles and blowing dust and sand could lower visibilities to near zero in some areas.
Boaters across the inner waters will be affected as well. Boaters trying to dock or drop anchor in northeast to east exposure such as Avalon Harbor and the east inlets and harbors of the Channel Islands could deal with rough seas through the period.
