Update 8:18 p.m. The National Forest Service has issued a mandatory evacuation order for cabins in the Kitty Creek drainage area and the Buffalo Bill Boy Scout Camp because of the Fishhawk Fire.
The fire has breached a line of protection that forced the evacuation notice, according to the Park County, Wyo., Sheriff's Office.
This is a developing story.
The Fishhawk Fire west of Cody, Wyo., grew 500 acres Wednesday and now covers 4,581 acres, fire officials said.
Firefighters got their new estimate from infrared mapping from an overflight. A Type 2 incident management team is being briefed on the fire Wednesday.
“This fire is in some rugged, hazardous terrain. Our number one priority is the safety of firefighters and the public; we are being tactical about what resources we use where and when it is safe to do so,” said Incident Commander Jay Slagowski in a statement.
The fire is within the Washakie Wilderness near Yellowstone National Park. The cause remains under investigation.
