Active weather warnings for Montana

# Montana Natural Disaster Report

**FLASH FLOOD WATCH ALERT FOR CENTRAL MONTANA:** The National Weather Service has issued a Flash Flood Watch for portions of central Montana, including southeast Lewis and Clark County and northwest Meagher County, effective through July 18 at midnight MDT. The primary concern is the Horse Gulch Burn Scar area, where scattered to numerous thunderstorms this afternoon and evening could produce heavy rainfall leading to dangerous flash flooding and debris flows. Residents in and near the burn scar should remain alert and prepared to evacuate if necessary. Heavy rainfall over the burn scar poses the greatest risk for localized flooding and debris flow hazards. Monitor weather updates closely and avoid areas near the burn scar during this period.

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.
