Firefighters have accomplished a great deal on the Roosevelt Fire since it started September 15 south of Bondurant, Wyoming but it has grown to over 60,000 acres, and only about half of the 172-mile fire perimeter has completed fireline.

The focus Sunday was on the southwest side of the fire in the North Dry Beaver Creek area west of Jim Bridger Estates. Firefighters have secured fire lines there, which reduces the threat. Additional resources have been allocated and a structure protection group is working the area ahead of the fire to protect homes.

On the north side of the fire adjacent to the highway, containment lines are in place and holding the fire south of the highway.

In Hoback Ranches, recovery efforts are underway in preparation of an organized repopulation of residents. Lower Valley Energy and Rocky Mountain Energy are working to restore destroyed infrastructure, while firefighters are clearing dangerous snags and suppressing hotspots as they occur. These efforts will continue for a number of days until it is safe for residents to return.

Personnel on the fire could receive help Tuesday night through Wednesday with a 30 to 70 percent chance of precipitation. There could be as much as a quarter-inch on Tuesday. From Thursday until Sunday the chance of additional precipitation is from 20 to 60 percent. Nighttime temperatures will be in the 20s and 30s.

Investigators determined that the fire was caused by an abandoned warming fire.

Highway 191 is fully open through the fire area with reduced speed limits and lane restrictions.

Roosevelt Fire approaches Highway 189/191

(UPDATED at 8:29 a.m. MDT September 25, 2018)

With the Roosevelt Fire approaching to within a quarter-mile of Highway 189/191 firefighters are again planning to conduct a burning operation on the southwest side of the road on Tuesday. They had hoped to start it Monday, but decided to postpone it.

The fire started September 15 and is 6 miles south of Bondurant, Wyoming.

Weather conditions Tuesday should be much more favorable than on Monday. After below freezing temperatures overnight, the forecast calls for 59 degrees, relative humidity in the teens, and west winds of 5 to 9 mph.

The fire grew by approximately 1,500 acres Monday to bring the total up to 49,805 acres. This was a smaller increase than in recent days, with most of the growth occurring on the east side where the perimeter roughly parallels Highway 189/191.

Firefighters on the Roosevelt Fire 30 miles south of Jackson, Wyoming are attempting to fight fire with fire. Their goal Monday through Wednesday of this week is to use a backfire on the southwest side of Highway 189/191 to burn off the vegetation ahead of the fire, hoping it will serve as a barrier as the main fire spreads into the already burned vegetation.

On Monday it was a very difficult task, with 10 to 12 mph winds out of the west and northwest gusting at 20 to 26 mph. These conditions could increase the chance of spot fires across the highway from burning embers lofted by the strong winds.

A Red Flag Warning is in effect for the area until 8 p.m. Monday. For Tuesday through Thursday the wind will decrease significantly. The temperatures will range from the teens at night to the 60’s during the day with little chance of precipitation. Those conditions should give firefighters a chance to make progress against the fire.

The fire is five miles south of Bondurant.

A mapping flight Sunday night at 9:20 determined that the fire had burned 48,348 acres.
