Active weather warnings for Alabama
Alabama residents in northern and southeastern regions face immediate weather hazards. A Dense Fog Advisory affects Madison, DeKalb, Jackson, and Marshall Counties through Monday morning, with visibility reduced to one-quarter mile or less creating hazardous driving conditions. Meanwhile, Geneva County in southeast Alabama is under a Flood Warning for the Choctawhatchee River at Geneva, with minor flooding expected late Monday night through Tuesday afternoon as river levels approach 23.0 feet. Motorists should exercise extreme caution in fog-affected areas, and residents near the Choctawhatchee River should prepare for potential minor flooding impacts and monitor conditions closely through Tuesday.
How Alabama’s rivers compare to normal
Every gauge placed by its own percent of normal, and three years of the statewide trend.
Where every gauge actually sits
One dot per Alabama streamgauge, placed by its own percent of normal. The state average is a single line through all of it.
Percent of normal compares today's discharge with the historical average for this calendar day. Tap any dot to open that gauge.
Alabama streamflow, three water years
Statewide percent of normal, every day since Oct 2023. The dotted line is normal.
799 daily readings from 114 reporting gauges. Percent of normal is today's statewide discharge against the historical average for the same calendar day — 100% is normal, not "good". The axis tops out at 250%: 13 readings above that — including the 381% peak in May 2025 — are drawn along the top edge, so a few flood days cannot flatten three years of everything else. The line breaks in 2 places where the record skips more than five days — those are gaps in reporting, not readings of zero.

As of October 12, 2026, Alabama rivers are running at 237% of normal across 115 USGS streamgauges, and the Alabama River At Claiborne L&D Near Monroeville is reporting the highest discharge at 16,300 cfs. The full sortable gauge table is below.
Which Alabama river is running highest right now?
As of October 12, 2026, the highest discharge in Alabama is 16,300 cfs on the Alabama River At Claiborne L&D Near Monroeville. See the sortable gauge table for the full statewide ranking.
Are Alabama rivers high or low right now?
Compare the statewide percent-of-normal on this page: above 100% means Alabama rivers are running higher than the seasonal average for the date, below 100% means lower (a dry spell or drought). Each gauge also shows its own percent of median.
Where does the Alabama 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 Alabama 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 Alabama 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.
