The National Weather Service is testing 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). This legacy system needed to be modernized to support newer innovation with technology supported by scalable infrastructure that uses services-driven architecture. Currently scheduled for Spring 2024, the NWS will replace AHPS with a new website, the National Water Prediction Service (NWPS). Existing AHPS content and features will be preserved and expanded within NWPS.

In order to ensure NWPS delivers capabilities that meet customer and public needs, the NWS will host a public testing period from November 15th, 2023 to December 15th, 2023. The goal of this testing phase is to collect feedback from you so that the feedback can be used to ensure NWPS delivers capabilities that meet your needs.
