Active weather warnings for Wisconsin
Wisconsin residents across the entire state face significant hazards through Monday. A statewide air quality alert remains in effect until noon Monday due to heavy smoke from wildfires, with Very Unhealthy (Purple) to Unhealthy (Red) PM2.5 levels expected, particularly affecting northeastern Wisconsin including Green Bay, Milwaukee, and surrounding areas. Sensitive groups, those with asthma or heart disease should limit outdoor activities and seek medical attention if symptoms worsen. Additionally, Beach Hazards Statements are active for Lake Michigan beaches in Door, Kewaunee, Manitowoc, Sheboygan, and Ozaukee Counties through Tuesday morning, with life-threatening waves of 2-4 feet and dangerous currents expected—avoid swimming at popular beaches including Rock Island State Beach, Baileys Harbor, Whitefish Dunes, and Point Beach. Severe storms with possible hail, damaging winds, and tornadoes are also forecast for Monday. Stay indoors when air quality is poor, avoid Lake Michigan beaches, and monitor local weather updates closely.

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.
