What's happening right now
An AI-generated daily summary stitched from active streamgauge readings, NWS warnings, and watershed status.
A severe flooding crisis is unfolding across the central and southern United States, with dozens of rivers and watersheds experiencing catastrophic streamflow levels—some exceeding 10,000% of normal capacity. The most dire situation is developing in north-central Texas, where the Wichita River near Wichita Falls has surged to an astronomical 10,802% of normal levels, while communities along the Illinois, Kentucky, and Wabash Rivers face immediate danger as water levels soar to nearly 900% above normal. This flooding emergency comes as federal disaster response teams continue cleanup efforts in Louisiana's Avoyelles Parish and as two flood-related fatalities have been confirmed in Madison County, Kentucky, underscoring the deadly nature of this rapidly evolving crisis.
The situation is particularly catastrophic in the Arkansas River basin and surrounding regions. In Kansas and Oklahoma, the Neosho River system is experiencing unprecedented flooding at 2,572% of normal flow, threatening communities near Coffeyville, Kansas and Miami, Oklahoma. The Arkansas River near Coon-Pickerel Creek has reached 4,130% of normal, putting Arkansas City, Kansas at extreme risk. Meanwhile, Texas communities face multiple threats: the Lampasas River near Lampasas has exploded to 4,723% of normal flow, the Richland Creek area near Corsicana shows 5,210% of normal, and the Frog-Mulberry watershed near Van Buren has reached an incomprehensible 5,100% of normal levels. In Louisiana, the Wichita River measurements indicate catastrophic conditions that could overwhelm levee systems and force mass evacuations.
The flooding extends throughout the Ohio and Mississippi River valleys, where critical infrastructure faces imminent failure. The Lower Kentucky River near Paducah is flowing at 884% of normal with over 75,000 cubic feet per second, while the Wabash River system—including areas near Vincennes, Indiana and the Illinois border—has surged to 189% of normal with flows exceeding 170,000 cfs. The Lower Ohio-Little Pigeon watershed near Evansville, Indiana shows the most alarming reading at 6,182% of normal flow. The Rolling Fork area near Hodgenville, Kentucky has reached 4,430% of normal, and the Rough River near Falls of Rough is at 4,468% of normal, threatening dam integrity and downstream communities. As Louisiana's agricultural commissioner outlines paths to federal aid for flood-damaged farms and low-income families remain trapped in repeatedly flooded areas with no evacuation options, authorities urge immediate action for residents in affected zones to seek higher ground before conditions deteriorate further.

What causes river flooding
Flooding is rarely a single-cause event — multiple factors usually compound. The most common drivers across the U.S.
Heavy rainfall
Persistent rain saturates soils and overwhelms drainage networks. Tropical systems and atmospheric rivers are the worst culprits.
Rapid snowmelt
Spring melt pulses can deliver months of accumulated water in days — especially when warm rain falls on existing snowpack.
Ice jams
Breakup ice can block channels, forcing water to back up and inundate upstream banks. Common on northern rivers in early spring.
Storm surge
Coastal hurricanes push seawater inland. Surge combined with rainfall is the deadliest flood scenario in U.S. history.
Reservoir releases
Controlled dam releases can dramatically increase downstream flow. USACE and USBR publish release schedules, but conditions change fast.
Burn scars
Wildfire-stripped slopes can't absorb rainfall — even modest storms produce dangerous flash floods on burned watersheds for years afterward.

Floodwaters rise faster than most people expect. The basics that save lives.
Flood map & river monitoring FAQ
What does "percent of normal" mean?
The current flow at a gauge compared to its seasonal average for this date. 100% means flow is right at the historical norm. 200%+ means twice the typical flow — a strong indicator of flood conditions on small-to-medium rivers.
What's the difference between a flood watch and a flood warning?
Watch: conditions are favorable for flooding within the next 12–48 hours. Warning: flooding is happening or imminent. Both come from the National Weather Service. Snoflo overlays both as toggleable layers on the map above.
How often does Snoflo's data refresh?
USGS streamgauge readings update every 15 minutes; we re-pull every hour. NWS warning polygons update as the NWS issues them — usually within 5 minutes. FEMA flood zones are static (the National Flood Hazard Layer is updated quarterly).
What is the FEMA flood zone layer?
FEMA's National Flood Hazard Layer (NFHL) shows the 1%-annual-chance ("100-year") and 0.2%-annual-chance ("500-year") floodplains. These are based on long-term hydrologic modeling, not current conditions. Useful for property risk; not a real-time signal.
Can I get an alert when my local river floods?
Yes. Save any USGS gauge as a favorite in the Snoflo iOS app, set a threshold (e.g. "alert me at 20 ft stage"), and you'll get a push the moment it crosses. Free with a Snoflo account.
Is Snoflo a substitute for official warnings?
No. Snoflo is informational. For life-safety decisions always follow guidance from local emergency management, the NWS, and law enforcement.
