A wildfire that sparked Wednesday afternoon near Big Bear Lake, Calif. had grown to 11,000 acres as of Friday morning, according to a government website.
The fire is the worst of the year, the Los Angeles Times reported. Wind and the dry undergrowth due to drought conditions in the area have contributed to the blaze’s rapid spread through sections of the San Bernardino National Forest. The fire is currently 10% contained, with fire engines, helicopters, air tankers and more than 500 respondents combating the spreading flames.
Hundreds in the area have been evacuated, but government website InciWeb stated that no structures had been destroyed as of Friday. The fire is currently spreading further inland to the south and east.
The fire’s cause remains under investigation.
