Active weather warnings for Louisiana
Louisiana residents should exercise caution as a Flood Warning remains in effect for the Calcasieu River near White Oak Park in southwestern Louisiana until early Tuesday morning, July 21st. Minor flooding is currently occurring and forecast to continue, with the river stage at 2.3 feet as of Thursday evening. Areas near Goos Ferry Road face potential inundation as water levels are expected to oscillate around the 2.0-foot flood stage threshold. Additionally, wildfire smoke from the US Midwest and East Coast is affecting air quality across Louisiana, prompting health officials to recommend residents remain indoors when possible. Residents in the Lake Charles area and surrounding communities should monitor water levels closely and avoid flooded roadways.

About Louisiana streamflow
Where does the Louisiana 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 Louisiana 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 Louisiana 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.
