Hydrologic Outlook
National Weather Service Great Falls MT
300 PM MDT Tue Jul 29 2025

 ...Additional heavy rain will impact saturated portions of North-
central and Central Montana through Saturday...

Soils across North-central and Central Montana are saturated due to
well-above normal precipitation over the past month. Showers and
thunderstorms will continue through at least Saturday over North-
central and Central Montana. The Weather Prediction Center has a
issued a Marginal Risk for excessive rainfall (5% chance for
rainfall to exceed flash flood guidance within 25 miles of a point)
Thursday through Saturday.

Showers and thunderstorms today through saturday will be slow moving
and produce rainfall rates capable of producing flash flooding. This
will lead to the potential for flash flooding to occur with the
greatest risk over urban areas, areas with poor drainage, and burn
scars. Small creeks and streams have the potential for a quick but
temporary rise downstream of any slow moving thunderstorm.

Stay tuned to the forecast for any watches, advisories, or warnings.
Please report any flooding to local law enforcement and have them
relay the report to the National Weather Service.
