Active weather warnings for Montana
# Montana Storm Center Report - July 16, 2026
Montana residents should exercise extreme caution due to multiple weather hazards affecting the state this morning and through Thursday evening. Dense fog advisories are in effect across Phillips, Valley, Daniels, and Roosevelt Counties until 9:00 AM MDT, with visibility dropping to a quarter-mile or less, creating hazardous driving conditions. Additionally, patchy dense fog in Fergus County's Milk River and Missouri River Valleys will impact visibility through late morning. A Flash Flood Watch remains active through Thursday evening for central Montana, particularly near the Horse Gulch Burn Scar in the Big Belt, Bridger, and Castle Mountains, with heavy rainfall expected to produce debris flows threatening areas including Maudlow, Trident, and York. Rainfall rates of 0.25 to 0.75 inches per hour are possible with thunderstorms. Residents should stay alert to local authority updates and avoid burn scar areas during heavy precipitation.

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.
