As of Wednesday morning, the Santa Ana wind-fueled Palisades Fire in Los Angeles had scorched more than 5,000 acres and destroyed an estimated 1,000 structures, many of them homes, officials said.

"We are not out of the woods yet. Please stay on guard for a fast-moving fire," the weather service's Los Angeles office warned.

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.

The threat of powerful wind gusts, combined with bone-dry humidity, in Los Angeles on Wednesday could test firefighters who have been battling to keep monstrous fires in Los Angeles in check since last week.

Officials are bracing for the return of fierce Santa Ana winds as they try to contain large blazes in the Los Angeles area. Here's the latest.
