Projected Incident Activity

Cooler temp and higher RH's will moderate any fire activity. Creeping and smoldering can be expected.

Remarks

Northern Rockies IMT 7 is managing both the Burnt Peak and South Yaak Fires.

Current Weather

Weather Concerns

Hot, dry, and gusty westerly winds will once again develop Thursday afternoon; however, cloud cover will increase, allowing for a minor increase in humidity. A pacific weather system with abundant atmospheric moisture will bring a return of wetting rainfall Friday. The forecast has quickly trended towards a wet solution. In fact there is a 40 to 60 percent chance for a half an inch or more of rainfall by Saturday morning across western Montana. A westerly flow will pattern will take shape Sunday into early next week, with seasonal temperatures expected.
