Active weather warnings for Delaware
Delaware residents should prepare for multiple environmental hazards through July 17th. A Heat Advisory affects New Castle County today, with heat index values reaching approximately 100°F from noon to 8 PM EDT, posing risks for heat-related illness. Simultaneously, Code Orange Air Quality Alerts have been issued statewide across all three counties—New Castle, Kent, and Sussex—due to elevated ground-level ozone and fine particle pollution. Sensitive populations including children, elderly residents, and those with asthma, heart disease, or lung conditions should limit outdoor activities and avoid strenuous exercise. All Delaware residents are advised to stay hydrated during the heat advisory and monitor air quality updates through the Delaware Department of Natural Resources and Environmental Control at dnrec.delaware.gov.

About Delaware streamflow
Where does the Delaware 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 Delaware 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 Delaware 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.
