Active weather warnings for Wisconsin

# Wisconsin Air Quality Alert Summary

Wisconsin is experiencing a statewide air quality emergency due to wildfire smoke, with PM2.5 levels reaching Unhealthy (Red) to Hazardous (Maroon) levels affecting virtually all counties through noon Friday, July 17. Major population centers including Milwaukee, Madison, Green Bay, and La Crosse are all impacted. All residents should avoid outdoor physical activity, while sensitive groups—including children, elderly, and those with asthma or heart disease—must remain indoors with minimal activity. People with asthma should keep quick-relief medication available, and those experiencing heart palpitations or shortness of breath should contact healthcare providers immediately. Air quality is expected to improve gradually Friday as winds shift, though eastern areas near Lake Michigan and Lake Superior may experience prolonged smoke impacts. Monitor https://airquality.wi.gov for real-time updates.

Flow report FAQ

About Wisconsin streamflow

Where does the Wisconsin 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 Wisconsin 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 Wisconsin 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.
