Active weather warnings for Montana
# Montana Storm Center Report
Montana is experiencing critical fire weather conditions and significant air quality degradation across western and central regions. Multiple Red Flag Warnings remain in effect through Saturday evening, with dangerously low humidity levels (7-20%), temperatures reaching 93-101°F, and gusty winds up to 30 mph creating conditions for rapid fire spread across Helena National Forest, Lewis and Clark National Forest, and fire zones spanning from the Flathead region through south-central Montana. Simultaneously, an Air Quality Alert affects 16 counties including those surrounding major population centers: Columbia Falls and Dillon are experiencing Unhealthy air quality, while Billings, Butte, Great Falls, Hamilton, Libby, and Missoula are Unhealthy for Sensitive Groups due to elevated wildfire smoke particulates. Residents with respiratory or heart conditions, the elderly, and children should avoid prolonged exertion, while all residents should limit outdoor activity. Outdoor burning is strongly discouraged, and fire containment efforts may be severely hampered through the weekend.

Flow report FAQ
About Montana streamflow
What are river levels like in Montana right now?
As of August 8, 2026, Montana rivers are running at 84% of normal across 172 USGS streamgauges, and the Clark Fork Near Plains Mt is reporting the highest discharge at 9,300 cfs. The full sortable gauge table is below.
Which Montana river is running highest right now?
As of August 8, 2026, the highest discharge in Montana is 9,300 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.
