Active weather warnings for Montana
# Montana Storm Center Report
Montana is experiencing widespread flood threats across multiple regions due to heavy rainfall and slow-moving thunderstorms through Sunday. A Flood Advisory is currently in effect for central Meagher County and east central Broadwater County until 1:45 PM MDT, with 1.5-3 inches of rain already fallen. Flood Watches extend through Sunday afternoon across south-central and southeast Montana, including areas near Billings, with 1-3 inches of rainfall expected and locally over 4 inches possible. Critical Flash Flood Watches are active over recent burn scars—particularly the Robertson Draw, East Side, Elk, McGhee-Remington, Sand Creek, and Bobcat Lakes burn areas—where debris flows pose significant hazards. Northeast Montana counties (Dawson, Garfield, Petroleum, Prairie, and Wibaux) face flooding risks through Sunday, while central Montana valleys near Helena and the Canyon Ferry area are under flood watch. Residents should avoid flooded roads, monitor local authorities for updates, and exercise extreme caution near burn scar areas where flash flooding and debris flows are most likely.

Flow report FAQ
About Montana streamflow
What are river levels like in Montana right now?
As of September 19, 2026, Montana rivers are running at 95% of normal across 171 USGS streamgauges, and the Clark Fork Near Plains Mt is reporting the highest discharge at 10,400 cfs. The full sortable gauge table is below.
Which Montana river is running highest right now?
As of September 19, 2026, the highest discharge in Montana is 10,400 cfs on the Clark Fork Near Plains Mt. See the sortable gauge table for the full statewide ranking.
Are Montana rivers high or low right now?
Compare the statewide percent-of-normal on this page: above 100% means Montana rivers are running higher than the seasonal average for the date, below 100% means lower (a dry spell or drought). Each gauge also shows its own percent of median.
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.
