Winds in the West are helping stoke wildfires sweeping across the Northern Rocky Mountains, Pacific Northwest and elsewhere, posing problems for firefighters trying to contain the flames fed by drought.

Weather was expected to worsen fires in some areas, as the federal government said it will exhaust its firefighting budget next month. A look at blazes in Western states:

Oregon

Two large fires have burned through buildings and forced evacuations as strong winds pick up, sending guests of a resort fleeing.

A fire on the Warm Springs Indian Reservation in rural central Oregon exploded to more than 50 square miles Friday, forcing evacuations of a rural subdivision and a resort that had 400 guests booked Thursday night.

The fire was expected to keep growing as strong winds push it through dry grassland. Sparks from a passing vehicle started the flames last week that destroyed three structures, including a mobile home.

In eastern Oregon, a 34-square-mile, lightning-sparked fire Friday burned 20-25 structures south of Canyon City and forced evacuations of residents in the area, while others were warned to be ready to leave quickly, KTVZ-TV in Bend reported.

Washington

Firefighters across the state are facing extreme heat and high winds as they battle large blazes and numerous smaller fires.

Hundreds of people were evacuating from the central city of Chelan as lightning-sparked wildfires advanced.

An uncontained blaze near Cougar Creek burned 28 square miles near the Yakima Indian Reservation. The state requested help Friday from the National Guard to fight that fire.

Idaho

Mandatory evacuations were put in place Friday for areas west of the city limits of Kamiah in the northwest because of a 20-square-mile fire, a TV station reported.

People in areas including Harrisburg East, Caribel, Tom Taha, Adams Grade, Kamiah proper, East Kamiah, Woodland Grade, Frasure Grade, Ridgewood and Fort Misery were told they should be packed and ready to leave at any time, KREM-TV in Boise reported.

A giant blaze on the Idaho-Oregon border grew to 414 square miles Friday, scorching grassland ranchers need to feed cattle and primary habitat for sage grouse, a bird being considered for federal protection.

Northern Rocky Mountains

Hot, dry weather has helped ignite dozens of new wildfires across the region, and lightning and strong winds were expected make things worse, officials said.

Thunderstorms could start new blazes and lead existing ones to spread but would not bring enough moisture to help crews battling the flames in drought conditions in Montana, Idaho and parts of North Dakota and Wyoming, said Bryan Henry of the Northern Rockies Coordination Center.

The weather helped the largest Montana fire, in Glacier National Park, spread from just a few acres last Sunday to more than 23 square miles Friday. It is uncontained in a remote area of the park, where it has forced some trail closures and is threatening two cabins, fire officials said.

California

Wildfires racing through the drought-stricken southern part of the state have burned over 3 square miles and two cabins.

A fire erupted shortly after 1 p.m. Friday in the Angeles National Forest northeast of Los Angeles.

Gusty winds quickly drove the flames through 800 acres of brushy ridges near Glendora. Two campgrounds containing at least 40 people have been evacuated.

National efforts

The U.S. Forest Service is spending about $100 million a week fighting wildfires and will exhaust its firefighting budget this week, Agriculture Secretary Tom Vilsack said Friday.

The agency will have to tap fire-prevention programs and other budgets, Vilsack said.
