Los Angeles Fire Department Chief Kristin Crowley said Tuesday that “life-threatening and destructive and widespread winds” are in the region, which could fuel the growth of new or existing wildfires in Los Angeles County and Ventura County.

Firefighters on Wednesday confronted persistently strong and dry winds fueling two giant wildfires that have terrified Los Angeles for eight days, testing the resolve of a city upended by the worst disaster in its history.
