POPE VALLEY, Calif. – Fire crews were battling a surging wildfire in rural Northern California that has burned more than 4 square miles, damaged five structures and prompted mandatory evacuations.
The fire began just after noon on Tuesday along Butts Canyon Road, northeast of Calistoga in Napa County, Fox40.com reported. It spiked to 2,700 acres by late Tuesday.
Officials say state firefighters and crews from Napa, Lake and Solano counties spent the day working in 90-degree weather as they contained 30 percent of the fire.
McCambridge says several residents living in two communities have been evacuated because nearly 200 homes are threatened.
Five structures have also been damaged, but it wasn't immediately clear whether they were homes or other buildings.
More than 300 firefighters were on scene, with 25 engines, six bulldozers, three helicopters and five tanker planes providing water drops, the San Francisco Chronicle reported.
No injuries have been reported. The cause of the fire has not yet been determined.
