SAN FRANCISCO (AP) - Officials say a raging wildfire in rural Northern California that has already spread over 5 square miles and forced the evacuation of 200 homes in Napa County is still growing.
State fire spokesman Daniel Berlant said Wednesday that the Butts Fire in remote Pope Valley has now grown to 3,800 acres from 3,200 acres.
He says that fire activity increased around noon while temperatures soared into the 90s as the blaze continued burning northeast into neighboring Lake County.
Berlant adds that more bulldozers have been requested to help crews strengthen containment lines.
The fire has already damaged one home and four outbuildings. In addition to the mandatory evacuations, another 180 homes were threatened.
The fire is not threatening any major vineyards.
No injuries have been reported, and the cause of the fire remains unknown.
