California Gov. Jerry Brown declared a state of emergency for Lake and Napa counties on Sunday, as rapidly growing wildfires blazed a path of destruction in the state.
Four firefighters were injured while battling the fire that grew to engulf 40,000 acres of land, up from 10,000 acres Saturday night.
The blaze, known as the Valley fire, is the latest in a slew of devastating wildfires that have swept through drought-stricken forest and brush on the West Coast this summer. The fires have left thousands of residents displaced, and many of their communities destroyed, Reuters reported.
More than one thousand firefighters are battling the flames of the Valley fire alone, which was zero percent contained as of Saturday.
Meanwhile, firefighters were battling 12 other fires in the area over the weekend, including the Butte fire, which began on Wednesday and was 20 percent contained on Sunday, according to Reuters.
Thousands of residents were forced to evacuate over the weekend after Gov. Brown on Friday also declared a state of emergency for those counties affected.
