Web Portal Changes: In Spring 2024, the Advanced Hydrologic Prediction Service (AHPS) hosted at https://water.weather.gov will be replaced by the National Water Prediction Service (NWPS) at a repurposed https://water.noaa.gov. A preview of NWPS is available here, where you can see your station hydrograph by replacing SSSSS with the station 5-character id: https://preview.water.noaa.gov/gauges/SSSSS.

Flood Inundation Mapping: Experimental real-time flood Inundation mapping services for 10% of the United States are now available via the NWS Map Viewer. Additional products and geospatial services depicting River Forecast Center and National Water Model forecasts continue to be accessible as described in the StoryMap here.
