Active weather warnings for Montana

# Montana Natural Disaster Report

Montana residents should exercise caution due to two active weather alerts. A High Wind Watch remains in effect through Saturday morning for Eastern Glacier, Western Toole, Central Pondera, and Northern High Plains counties, with west winds reaching 30-35 mph and gusts potentially exceeding 60 mph—travel will be difficult, particularly for high-profile vehicles. Additionally, a Dense Fog Advisory is currently active until 10 AM MDT this morning across northeastern Montana counties including Daniels, Dawson, Roosevelt, Richland, Sheridan, and Wibaux, with visibility reduced to one-quarter mile or less. Motorists in these regions should reduce speed, increase following distances, and exercise extreme caution during commutes.

799 daily readings from 169 reporting gauges. Percent of normal is today's statewide discharge against the historical average for the same calendar day — 100% is normal, not "good". The line breaks in 2 places where the record skips more than five days — those are gaps in reporting, not readings of zero.

Flow report FAQ

About Montana streamflow

What are river levels like in Montana right now?

As of September 24, 2026, Montana rivers are running at 104% of normal across 171 USGS streamgauges, and the Clark Fork Near Plains Mt is reporting the highest discharge at 10,500 cfs. The full sortable gauge table is below.

Which Montana river is running highest right now?

As of September 24, 2026, the highest discharge in Montana is 10,500 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.
