Santa Ana Winds Spread Bond Fire Over 6,400 Acres

Two forest service firefighters have been injured in the Bond Fire, which by December 4 had scorched more than 6,000 acres in Orange County, California, according to the Orange County Fire Authority.

This footage shows the smoke cover clouding the afternoon sky in a neighborhood on Thursday.

A red flag warning was in effect through Friday.

The OCFA had earlier approximated the affected area at over 7,000 acres, but more accurate mapping later suggested the fire was at 6,400 acres and 10 percent contained by early Friday.

Around 25,000 residents had been evacuated. Credit: @Espina_Negra via Storyful
