Active weather warnings for Montana
# Montana Storm Center Report
Montana faces multiple hazardous weather threats through Monday evening. A Flood Warning is in effect for small streams in northwestern Montana, including the Mission and Swan mountain ranges, with flooding already occurring or expected imminently in Polson, Evergreen, Columbia Falls, Ronan, St. Ignatius, Pablo, and Bigfork due to 1-3 inches of rainfall already fallen and an additional 1-2 inches possible. A Flood Watch continues for the Clark Fork River above Missoula through Wednesday afternoon, with flood stage potentially reached late Monday morning. The West Glacier Region, including Going-to-the-Sun Road in Glacier Park, faces flooding risks from rain and snowmelt through Monday morning. Additionally, a Lake Wind Advisory remains in effect for Fort Peck Lake until Monday evening, with west winds 20-30 mph gusting to 40 mph creating wave heights exceeding 4 feet and hazardous conditions for small craft.

Flow report FAQ
About Montana streamflow
Where does the Montana streamflow data come from?
The U.S. Geological Survey National Water Information System. USGS streamgauges report continuously (every 15 minutes) and the data is the canonical real-time record for U.S. rivers. Snoflo pulls the latest readings and joins them to a 7-day NOAA weather forecast for each station.
What is cfs?
Cubic feet per second — the standard unit for streamflow. One cfs is about 7.5 gallons per second. Small creeks run at single-digit cfs; the Mississippi at hundreds of thousands.
What does Gauge Height mean?
The water level at the gauge in feet above the reference datum. Used together with discharge to track river state. Flood stage and runnable levels are typically expressed in gauge height (e.g., "flood at 16 ft").
How fresh is the Montana data?
USGS streamgauges report every 15 minutes; Snoflo re-pulls throughout the day. The AI briefing regenerates daily.
Can I get a flow alert for a Montana gauge?
Yes. Save any USGS gauge as a favorite in the Snoflo iOS app, set a discharge or stage threshold (e.g. "alert me when discharge crosses 2,000 cfs"), and you'll get a push the moment it crosses.
Is this a substitute for an NWS flood warning?
No. Snoflo is informational. For flood life-safety decisions always follow guidance from your local NWS forecast office and state emergency management. Snoflo data is one input among several.
