The National Weather Service has issued an urgent wind warning, cautioning residents about gusty winds expected Wednesday afternoon through Thursday morning.

A fast-moving frontal system is causing windy conditions in the Antelope Valley that will move to the northwest. The focus of the strongest winds are expected in the I-5 corridor, the valleys of Los Angeles County and western Antelope Valley.

The peak of the wind event is expected Wednesday night, with damaging wind gusts of more than 75 MPH expected.

The combination of very strong winds, blowing snow and ice will cause treacherous conditions across the I-5 corridor near the Grapevine, where a winter storm warning is already in effect.

This wind event has the potential to be one of the most widespread and strongest wind episodes in recent years. With the ground rain-soaked by recent storms, there will likely be widespread downed trees across the region, as well as downed power lines and power outages.

A high wind warning means that winds are in excess of 40 MPH with possible gusts greater than 60 MPH. Be alert for flying debris; if on the road, watch for fallen trees and downed power lines. If at home, secure patio furniture and items that may become airborne; latch the doors and windows and stay indoors, if possible.
