Active weather warnings for Alabama
Alabama residents in south-central, southwest, and southeast portions of the state should exercise caution through this evening due to active weather threats. A Wind Advisory remains in effect until 7-8 PM CDT, with north winds gusting 20-40 mph expected to impact areas including Mobile and Baldwin counties. Given recent damage from Hurricane Isaias, these gusty winds pose significant hazards, capable of downing weakened trees, causing power outages, and scattering debris across roadways. Residents should secure loose outdoor objects and avoid unnecessary travel. Additionally, dangerous rip currents are expected along Alabama's coastal counties through Tuesday morning, with swimmers advised to stay out of the water or exercise extreme caution. Monitor local weather updates and heed all advisory warnings.
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.

Are Alabama rivers high or low right now?

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.
