NWPS River Rise Forecasts
The National Weather Service's National Water Prediction Service (NWPS) is an online tool for accessing real-time (observed) and forecasted streamflow and gage height information for specific flood forecast points.
Streamflow, radar and runoff modeling are incorporated to provide updated, graphical flood forecast information.
In normal (non-flood) conditions, these pages are updated every 1-3 days; during times of flood, updates occur several times a day.
Note: the NWPS replaced the Advanced Hydrologic Prediction Service (AHPS) in late March 2024.
Flood Forecast Points: Upper Basin
The NWPS issues forecasts for locations along the Upper Delaware River, including:
Interactive Map (Includes locations on several tributaries as well as the four flood forecast points on the Delaware River listed above)
Flood Forecast Points: Lower Basin
The NWPS issues forecasts for the following locations along the Delaware River:
Interactive Map (Includes locations on several tributaries as well as the nine forecast points ontheDelaware River listed above)
Flood Forecast Points: Tidal
The NWPS issues forecasts for the following locations along the tidal Delaware River:
Interactive Map (Includes locations on the Schuylkill River and several other tributaries as well as the nine forecast points on the tidal Delaware River listed above)
Flood Inundation Maps
Flood inundation maps provide information on the spatial extentof flood waters in the vicinity of NWS river forecast locations.
Users are able to display flood inundation maps for various levels ranging from minor flooding through the largest observed flood.
Flood inundation maps, combined with river observations and NWS forecasts, enhance the communication of flood risk and provide users additional information needed to better mitigate the impacts of flooding and plan for more resilient communities.
Flood inundation maps are now available for the following nine flood forecast locations along the Delaware River main stem as well as theAssunpink Creek at Trenton, N.J. :
