Aug. 23 (UPI) -- A fast-growing wildfire in Nevada has grown to 10,000 acres since it began burning just outside Reno on Saturday, officials said.

The Hawk Fire remained uncontained as of Sunday and forced 14,000 homes to be evacuated.

Gov. Joe Lombardo declared a state of emergency in Washoe County, which contains Reno, and urged residents to stay vigilant and heed warnings.

"This is an active and rapidly evolving situation, and I urge everyone in the affected areas to remain vigilant and follow the direction of local officials," he said in a statement on X.
