Hundreds of wildfires sparked by lightning flared Sunday across the heart of wine country and remote forests in Northern California, the latest batch of destructive blazes in the bone-dry state.
One had spread across nearly 6 square miles by early Sunday after starting the previous afternoon in Napa County and quickly moving into a mostly rural area of Solano County.
The fire threatened more than 100 buildings as it fed on grassy woodland about 40 miles southwest of Sacramento, said Roger Archey, a spokesman for the California Department of Forestry and Fire Protection, or Cal Fire.
It was 35 percent contained Sunday evening and had destroyed one home, officials said. Evacuations were ordered for some residents, said agency spokeswoman Nancy Carniglia.
Wildfires have destroyed more than 175 homes in Northern California so far this year.
