The Los Angeles Fire Department described Thursday night's fires in Pacoima as a "major emergency," with more than 130 firefighters responding.

The fire sparked in the Los Padres National Forest in San Luis Obispo County and was growing exponentially, officials warned. The area is mostly uninhabited.

The Madre Fire is the largest wildfire in California in 2025 — surpassing the Los Angeles-area fires that devastated parts of the region in January.

Emergency crews responded midday Thursday to a fire at the home in Simi Valley, located in Ventura County in the greater Los Angeles area.

Video shows a fireworks warehouse exploding in California, causing residents near the area to evacuate, according to officials. The warehouse is located in Yolo County, California, northwest of Sacramento.

California has seen a spate of accidental fireworks explosions leading up to the Fourth of July with a Wednesday morning detonation killing 1 in a Simi Valley home and a similar incident critically injuring two people in a Bay Area residence.
