Hydrologic Outlook
National Weather Service Great Falls MT
420 AM MDT Tue May 7 2024

A moisture rich spring weather system will bring prolonged periods
of lower elevation rain and mountain snow to much of Central and
North-central Montana through early Thursday. NBM probabilistic
guidance supports widespread rainfall amounts in the 1 to 3 inch
range over much of Central/North-central Montana, with the highest
amounts occurring along and southeast of a Havre to Great Falls line.

While impactful flooding is generally not expected, some rivers,
creeks,and streams along the Canadian border in Hill and Blaine
Counties are expected to approach or reach action stage Wednesday
and Thursday, mainly impacting unpopulated rural locations.

Additionally, any low lying area that receives heavier rainfall will
be susceptible to ground saturation and ponding of water. Anyone
near waterways should remain alert for changing conditions and be
prepared to seek higher ground should water rises occur. Travelers
should anticipate wet roads and the potential for hydroplaning due
to ponding of water on area roadways.
