The National Weather Service has launched a new river observation and forecast website!
 


For more than two decades, the National Weather Service (NWS) has delivered river observations and forecast products and services via the Advanced Hydrologic Prediction Service (AHPS). The NWS has replaced AHPS with a new, enhanced website, the National Water Prediction Service (NWPS). Existing AHPS content and features will be preserved and expanded within NWPS.

You can provide feedback on the upgraded site here.

 

Legacy AHPS - Advanced Hydrologic Prediction Service NWPS - National Water Prediction Service

 

NWPS Page features:

  • Dynamically-plotting hydrographs (example: Sac River @ I Street Bridge)
  • Improved web map functionality and improved base maps and hydro-specific spatial layers
  • Application Programming Interface (API) - partners can leverage directly into their own applications
  • Summary of these features is on this Story Map

Note: The California-Nevada River Forecast Center's (CNRFC) page will continue to be available with the same look and feel.
