Hydrologic Outlook
National Weather Service Missoula MT
1233 PM MST Wed Dec 10 2025
The flood watch has been cancelled, but hydrologic impacts remain a
minor threat through Friday morning. The break in the rain is
allowing creeks and streams to flush out and build capacity for the
next round of moisture tomorrow. This next round will still cause an
increased risk of rock falls and some ponding of water in low lying
areas.
Warm overnight temperatures will cause some snow melt in addition to
another round of rain coming in. So further stream and river rises
are expected, but at this time we do not expect further rises to
measure up to the level of floods.
