A wildfire in the San Bernardino National Forest exploded to 225 acres and was 0% contained Sunday, prompting a mandatory evacuation order for Pinyon Crest and the partial closure of state Route 74.
Evacuation warnings were also issued for the nearby communities of Pinyon Pines and Alpine Village.
Flames were first reported about 11:05 a.m. west of the Pinyon Flat campground in the Santa Rosa and San Jacinto Mountains National Monument about eight miles south of Palm Desert, according to the California Highway Patrol.
U.S. Forest Service and Riverside County firefighters were responding to the fire, which they reported was spreading at a moderate rate and jumped state Route 74 in a northeasterly direction.
According to the CHP, one structure had been surrounded by the flames around 11:35 a.m., though it was unclear what the structure was and whether it was occupied.
State Route 74 was shut down in both directions between state Route 371 near Garner Valley and Palowet Drive in Palm Desert. The public was asked to avoid the area.
An evacuation center was set up at Idyllwild Elementary School, 26700 state Route 243, Idyllwild. Large and small animals can be taken to Petland Animal Shelter, 72049 Petland Place, Thousand Palms.
Meanwhile, a public information line for the fire was set up at 951-940-6985.
The blaze comes just as a ridge of high pressure begins to move over the Southland, bringing temperatures 15 to 20 degrees above average, low humidity and elevated fire danger.
According to the National Weather Service, valleys, mountains and desert slopes will be most susceptible to fires in the afternoons and evenings, as relative humidity drops to single digits and temperatures reach triple digits in the Inland Empire.
“These elevated fire weather threats while not critical, will be greatest Tuesday through at least Friday,” the NWS said.
