A van parked in the Highland Park section of Los Angeles and another car are shown damaged by trees early Thursday, Dec. 1, as high winds up to 50 and 60 MPH tore through the southland. High winds flipped over trees and trucks and knocked out power to more than 300,000 California customers.

In Southern California, high winds blew over at least six semitrailers before dawn on highways below the Cajon Pass in San Bernardino County, said California Highway Patrol Officer Mario Lopez. One trucker was taken to a hospital.

Twenty-three flights were diverted and several delayed beginning Wednesday at Los Angeles International airport because of severe crosswinds and debris on runways, officials said. An hour-long power outage Wednesday evening affected all passenger terminals. The winds had died down by Thursday morning but some delays were reported in both arriving and departing flights, Federal Aviation Administration spokesman Ian Gregor said.  Read full story
