Active weather warnings for Alabama
Tropical Depression Two is expected to strengthen into a tropical storm today and impact Alabama's coastal regions Tuesday through Wednesday. A Tropical Storm Watch is in effect for Baldwin and Mobile counties, including coastal communities such as Gulf Shores, Orange Beach, Dauphin Island, and Bayou La Batre, with potential tropical storm-force winds of 39-57 mph. Residents should prepare for dangerous surf exceeding 10 feet, deadly rip currents beginning Monday night through the week, and storm surge of 1-3 feet during high tide Wednesday-Thursday, particularly affecting the Mobile River Delta and downtown Mobile area. Localized heavy rainfall around 1 inch is possible across coastal counties, and scattered power outages may occur. Additionally, a Heat Advisory is in effect across north-central and northwest Alabama with heat indices reaching 105-109°F through Tuesday evening. Coastal residents in Baldwin and Mobile counties should complete storm preparations immediately, secure loose objects, monitor weather.gov and NOAA Weather Radio, and follow local evacuation orders if issued.

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.
