A raging wildfire in rural Northern California that spread over 5 square miles and forced the evacuation of 200 homes in Napa County continues to grow, officials said Wednesday.
By early evening, the Butts Fire in remote Pope Valley grew to 3,800 acres from 3,200 acres, said Daniel Berlant, a spokesman for the California Department of Forestry and Fire Protection. The blaze is not threatening any major vineyards, Berlant and a spokeswoman for a vintners association said.
More than 1,000 firefighters were hoping to get a better handle on the blaze after they made progress overnight Tuesday, Berlant said. But fire activity increased about noon Wednesday as temperatures again soared into the 90s and the blaze continued burning northeast into neighboring Lake County. The blaze is 30 percent contained, officials said.
"We're hoping that once the sun goes down, the temperature will as well and the humidity will also rise to give us another chance to increase containment," Berlant said.
Crews have requested more bulldozers from across the state to assist the dozen on site in strengthening containment lines, Berlant said.
The fire has damaged one home and four outbuildings. In addition to the mandatory evacuations, another 180 homes were threatened. No injuries have been reported, and the cause of the fire remains unknown.
The fast-moving blaze began Tuesday afternoon in Napa County. Within hours, it covered 600 acres and then spiked to 2,700 acres by late evening as it spread northeast. State firefighters and crews from Napa, Lake and Solano counties spent a second day working in 90-degree weather on Wednesday.
Similar high temperatures were expected again on Thursday. The fire exploded because of dry conditions across the state, Berlant said.
The fire is not affecting the lucrative Napa Valley vineyards nearby, fire officials said. Pope Valley is about 20 miles north of Napa Valley.
Cate Conniff, a spokeswoman for the Napa Valley Vintners, a nonprofit trade association, agreed. "It has not come anywhere close to what we consider NapaValley wineries. It is moving in the opposite direction, and it continues to move that way. We're keeping an eye out on it," Conniff said
Gov. Jerry Brown said Wednesday that he has secured federal funds to help fire departments absorb some of the cost of fighting the fire.
Elsewhere in California, firefighters were surrounding a blaze in Shasta-Trinity National Forest that forced the evacuation of about 15 homes. Forest spokeswoman Andrea Capps said the fire has burned through 35 acres since it started Tuesday and was 70 percent contained.
