The National Weather Service is transitioning to a new Rivers and Lakes Observation and Forecast Website!

NWPS implemented on March 27, 2024...AHPS to be retired on May 28, 2024!


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). This legacy system needed to be modernized to support newer innovation with technology and provide a more mobile-friendly user experience. On March 27, 2024, the NWS replaced AHPS with a new website, the National Water Prediction Service (NWPS). AHPS will continue to be active for 60 days following NWPS implementation. On May 28, 2024, AHPS will be retired and no longer available.

Old: Advanced Hydrologic Prediction Service (AHPS) New: National Water Prediction Service (NWPS)
