In Southern California, more than 100 firefighters responded on July 10, 2026, to the fast-moving Grande Fire near Lake Piru on the Los Angeles–Ventura county border. The brush fire ignited around 2:20 p.m. south of Highway 126 and east of Lake Piru amid triple-digit temperatures and a regional heat wave. Burning through steep, hard-to-access terrain, the blaze triggered evacuation warnings for several zones, including PIRU 01, PIRU 14, and CDER 01, as residents were urged to prepare to leave and limit smoke exposure. An interagency effort, supported by air tankers and helicopters using a nearby water source, stopped forward spread at about 30 acres by 4:00 p.m.
