Fires have spread resources thin across Wyoming and Montana, after lightning caused multiple fires throughout the week. Warm temperatures and low humidities have created dangerous fire conditions for these areas.
Here's the latest on those fires from the Associated Press.
Two fires contained in Wyoming
UNDATED (AP) - Firefighters have contained a 14,400-acre
wildfire west of Wheatland.
The fire was started by lightning last weekend. It was declared contained late Thursday afternoon.
Firefighters have also surrounded a separate wildfire in
Converse County and another just west of Dubois.
A 4,000-acre fire north of Gillette continues to burn but
firefighters report good progress thanks to cooperative weather Thursday.
Much of the effort to battle the Hole in the Wall fire that started in northern Wyoming has switched to the Montana side after the fire crossed into that state. The fire has burned about 5,700 acres and is 50 percent contained.
Four other fires are burning in remote areas of Wyoming and are just being monitored for now.
Crews battling wildfires in western, southeastern Montana
BILLINGS, Mont. (AP) - A complex of wildfires in western Montana that surged across the Continental Divide from Idaho earlier this week grew Thursday to more than 21,000 acres.
The Ravalli County Sheriff's Office told residents in about 50 homes near Painted Rocks State Park to be ready to leave on short notice. The blaze was burning in steep terrain that had not been hit by fire in more than a century.
Meanwhile, crews say they have gained ground on a 20,000-acre complex of fires on the Northern Cheyenne Reservation in southeastern Montana.
An estimated two dozen homes and other structures were
threatened by the five wildfires comprising the complex near Lame Deer, Mont.
No evacuations had been ordered, but speed limits were reduced along state Highway 212 in the area due to limited visibility.
Yellowstone raises fire danger to 'very high'
YELLOWSTONE NATIONAL PARK (AP) - The fire danger in
Yellowstone National Park has been raised to "very high."
Yellowstone has seen 10 fires so far this season but nothing major. All park services and facilities are open.
A new fire was discovered in Yellowstone on Thursday. The Heart Fire is located in the south central portion of the park, just northeast of Heart Lake. It is only a tenth of an acre in size. Another active fire has burned about six acres in the backcountry over the last month about 3 miles east of Madison Junction.
Meantime, the National Weather Service issued a red flag warning Thursday for the Gallatin National Forest, which adjoins the north and west sides of Yellowstone.
