ESFTFX Monsoon moisture will slowly move northward and bring periods of widespread rain and embedded thunderstorms to Southwest and portions of Central Montana Tuesday night through Friday. Localized heavier downpours in excess of a half inch per hour can be expected with the heavier cells in addition to the general four day storm totals between a quarter to an inch and a half. The most persistent and heaviest rainfall is expected along and south of I90 on Wednesday and Thursday. Impacts will mostly be limited to sensitive burn scars or other normally flood prone locations or areas of steep terrain and may include instances of localized flooding, debris flows, and rock slides. Those considering any backcountry travel for Wednesday and Thursday of this week should be prepared for periods of excessive rainfall, muddy roads, and potential localized flooding.

ESFMSO Where: Lemhi, Idaho, and Clearwater Counties in Idaho Ravalli, Mineral, Missoula, Granite, Deer Lodge, Powell, and Silverbow Counties in Montana What: Confidence continues to trend higher that Monsoon moisture will be spreading north into the Northern Rockies by Wednesday, bringing a chance for scattered thunderstorms. These thunderstorms will be capable of producing rain rates in excess of one half inch per hour. The result will be the potential for rock and debris slides in steep terrain along Forest Service roads and recent burn scar areas, as well as Highway 93 from Riggins to Whitebird in Idaho and Skalkaho Road in Montana. Consider delaying any backcountry travel for Wednesday and Thursday of this week.
