Hydrologic Outlook
National Weather Service Missoula MT
1121 AM MDT Tue Aug 26 2025

...Rock and mudslides due to excessive rainfall...

Where: Clearwater County in Idaho and Mineral, Missoula, Granite,
       Deer Lodge, Powell, and Silverbow Counties in Montana.

What: Confidence remains high that Monsoon moisture will be
spreading north into the Northern Rockies Wednesday bringing a
chance for scattered thunderstorms. These showers and 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.

Consider delaying any backcountry travel for Wednesday and Thursday
of this week.
