A rapidly spreading brush fire has triggered evacuation orders in a sparsely populated area of Los Angeles County, fueled by scorching temperatures and exceptionally dry conditions.

The blaze ignited around 1 p.m. on Friday in a remote high desert region, approximately 45 miles northeast of Los Angeles.

Temperatures in the area soared to nearly 100 degrees Fahrenheit, according to the LA County Fire Department.

By Friday evening, the fire had consumed approximately 2,700 acres, Angeles National Forest officials reported on X.

The number of structures currently at risk remains undetermined, though the American Red Cross has opened a shelter at a local YMCA.

Nearby Piñon Hills, a community of about 7,200 residents in San Bernardino County, saw parts of its area placed under an evacuation warning.

This incident unfolds as much of the US braces for a significant heatwave this weekend, driven by an unusually potent and prolonged heat dome.

This weather pattern is expected to elevate wildfire risks in already drought-affected regions, with temperatures forecast to be 15 to 25 degrees Fahrenheit above average in some areas.
