The Lake Fire has engulfed more than 10,000 acres and destroyed at least three structures since igniting Wednesday afternoon in Northern Los Angeles County.

Plumes of smoke could be seen Thursday morning over the Angeles National Forest near Lake Hughes, as the blaze gobbled up thick forests of chaparral and brush, in an area that hasn’t burned in decades.

Ground crews worked overnight to establish perimeters around the fire and protect structures, with over 5,000 homes and buildings threatened, according to the Los Angeles County Fire Department. Despite early morning showers, the fire was 0% contained, as of 10 a.m. Thursday morning.

“This will be a major fire for several days,” said Robert Garcia, Angeles National Forest Fire Chief. Hot and dry conditions are expected to fuel the fire over the weekend, with temperatures creeping into the mid-90s.

Mandatory evacuations are in place for areas near Lake Hughes and Castaic Lake. Temporary shelters have been opened, though officials are asking evacuees to stay in their cars outside of the centers due to concerns over Covid-19.

The Lake Fire is one of 24 active blazes in California, and Direct Relief is monitoring the situation and will assess health needs as they arise.
