The Madre Fire has spread to more than 50,000 acres and was only 10 percent contained, according to Cal Fire
A fast-spreading wildfire in central California became the state's largest this year after reaching explosive proportions overnight as high temperatures and dry conditions increased the risk of wildfires ahead of the July 4th holiday.
The Madre Fire broke out on the evening of July 2 in a remote area of ??central California. California, near Highway 166, according to Cal Fire. The fire quickly spread to more than 35,000 acres (14,000 hectares) overnight, burning grasslands in a section of Los Padres National Forest.
As of around 9:30 p.m. PT on July 3, the fire had grown to nearly 50,000 acres (21,000 hectares) and was 10% contained, according to Cal Fire. Evacuation orders and warnings were issued for small communities near Highway 166 as the blaze moved into Carrizo Plain National Monument, about 70 miles (111 kilometers) southeast of San Luis Obispo, California.
The National Weather Service in Los Angeles reported that satellite imagery showed the fire impacting inland San Luis Obispo County, with a plume of smoke extending southeast of the fire over Santa Barbara and Ventura counties. Videos and images shared by the U.S. Forest Service also showed smoky skies and flames moving across mountainous terrain.
“With current weather, terrain, and fuel conditions, this fire has experienced exponential growth in less than 24 hours across multiple counties surrounding the San Luis Obispo County area,” the U.S. Forest Service said in a statement July 3. “The smoke impact will be far-reaching.”
