Incident Photo for the Black Mountain Fire

The lightning-caused Black Mountain fire was reported to the Dillon Interagency Dispatch Center on July 17, 2021. The fire is located 13 miles south of Jackson, MT and east of Skinner Lake and Skinner Meadows in both the Dillon and Wisdom Ranger Districts. Due to current access issues, heavy dead and down fuel and expected fire behavior, fire managers are preparing indirect line around many parts of the fire to protect the highest values at risk. These tactics may change should conditions warrant.

The fire is being managed by the Southwest Type 1 Team #1, Incident Commander Alan Sinclair.  

Forest Closure Orders are in effect for the fire area. Please see up to date closure order at Beaverhead-Deerlodge NF: Beaverhead-Deerlodge NF Closure.

Planned Outlook

Planned Actions:
A hotshot crew will be going direct. The purpose of this action is to secure the Black Mountain Fire which will prevent further growth, exposure, and resource commitment. We will accomplish this with direct suppression of the fires edge. Lookouts will be posted, crew capabilities match assignment, medical extraction and care is provided and weather will be closely monitored with trigger points established to remove resources from direct attack. Continue construction of indirect holding lines utilizing heavy equipment and crews.
Projected Incident Activity:
12 hours: Low to moderate fire behavior is expected overnight

24 hours: Red Flag conditions will allow for very active fire behavior

48 hours: Moderate to active fire behavior is expected with the drying conditions

72 hours: Low humidity along with the winds will dry the fuels allowing fire behavior to increase

Anticipated after 72 hours: More moisture will keep fire behavior moderate to low. Very little movement is expected.

Weather Synopsis

Weather Concerns:
Today was another very warm and dry day. Temperature climbed into the 80s, as relative humidity values dropped into the teens. Isolated high-based showers and a few dry thunderstorms developed across the region this afternoon.

On Thursday, a Red Flag Warning is in effect for 1200 to 2400 hours, as a mixture of wet and dry thunderstorms are anticipated to bring strong outflow winds, possibly in excess of 50 mph, to southwest Montana. While winds and cloud-to-ground lightning are the primary concern with these thunderstorms, large hail is also possible. Little to no precipitation is expected with these thunderstorms. Temperatures are expected to warm into the upper 70s, near 80, with relative humidity values dropping into the 15 to 25 % range.
