Active weather warnings for Montana
# Montana Storm Center Report
Montana residents in south central and southwest regions should prepare for significant flood risks through July 23rd. The National Weather Service has issued Flood Watches for multiple areas including the Absaroka/Beartooth Mountains, Livingston Area, Red Lodge Foothills, and southwestern mountain regions around Gallatin, Madison, and Beaverhead counties. Slow-moving thunderstorms capable of producing very heavy rainfall are expected this afternoon and evening, with particular concern for flash flooding in recent burn scar areas including Robertson Draw and the East Side south of Red Lodge. Low-lying areas, poor drainage zones, and flood-prone locations face elevated risk of excessive runoff affecting rivers, streams, and creeks. Residents in affected mountainous and foothill communities should avoid flooded roadways and stay alert for rapidly changing conditions through tonight.

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.
