Active weather warnings for Alabama
Alabama is facing multiple weather hazards requiring immediate attention. Tropical Storm Bertha is moving westward off the Gulf Coast, triggering Tropical Storm Warnings for coastal Mobile and Baldwin Counties, including communities like Mobile, Daphne, Fairhope, Foley, Dauphin Island, and Bayou La Batre. Residents should expect tropical storm force wind gusts of 40-50 mph along immediate coastal areas, potential storm surge of 1-3 feet through Thursday morning, and dangerously large 8-12 foot breaking waves with life-threatening rip currents. A High Surf Warning and Coastal Flood Advisory remain in effect, with minor flooding expected in typically vulnerable areas during high tides. Inland, a dangerous Heat Advisory affects central Alabama counties including Tuscaloosa, Jefferson (Birmingham area), Shelby, and surrounding regions, with heat index values reaching 104-105°F through 9 PM today, posing heat illness risks. Residents should avoid coastal areas, secure loose outdoor items, monitor weather.gov for updates, and take precautions against extreme heat.

About Alabama streamflow
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.
