As weather conditions improve and firefighters make progress in containing the Los Angeles wildfires, they’re still contending with dangerous conditions as they work to extinguish the flames.

“We are not out of the woods yet,” Los Angeles Mayor Karen Bass said Wednesday as Cal Fire warned of “extreme hazards and the potential for fire growth.”

The Palisades Fire — the largest of three major fires ravaging Los Angeles County – is still just 21% contained, burning across 23,713 acres, according to Cal Fire. The Eaton Fire – the most destructive fire in Southern California history – is only 45% contained. Meanwhile, at least 25 people have died and thousands of structures have been incinerated by the blazes.
