Dear Partners, As outlined in the National Weather Service (NWS) Strategic Plan <https://www.weather.gov/media/wrn/NWS-2023-Strategic-Plan.pdf>, the NWS is investing in its infrastructure. This strategy includes the modernization and replacement of the Advanced Hydrologic Prediction Service (AHPS) <https://water.weather.gov/ahps/> web dissemination platform with the National Water Prediction Service (NWPS) on or around March 27, 2024. We recognize that AHPS provides you and others with critical hydrologic information, especially during extreme hydrologic events, and as such we are sharing information here about the transition not only to help you prepare but also to ensure there are no gaps in service. Below is key information for you: - What is NWPS: The NWPS web dissemination platform will be the replacement for AHPS. NWPS will leverage the NWS’ Dissemination Cloud infrastructure, a modernized Web technology framework incorporating geospatial technology and web services to disseminate critical hydrologic information to you year round. In addition to the enhanced Graphical User Interface (GUI), NWPS will include an Application Programming Interface (API) that will allow you to integrate operational forecast information within your own applications. Information on the NWPS access, use, evaluation and training material is available at https://www.weather.gov/owp/operations. - Service Change Notice: - A Service Change Notice <https://www.weather.gov/media/notification/pdf_2023_24/scn24-03_exp_nwps_website_t2o.pdf> (SCN) <https://www.weather.gov/media/notification/pdf_2023_24/scn24-03_exp_nwps_website_t2o.pdf>(listed here: https://www.weather.gov/notification/ <https://www.weather.gov/notification/#scn>) was posted on Friday, January 12, announcing the 75-day transition of the experimental NWPS service to operational status. - https://preview.water.noaa.gov will still be available until March 27, 2024 with minor interruption. It is advised that the public and NWS partners continue to familiarize themselves with this webpage. - Operational Implementation: On or about March 27, 2024 NWPS will become fully operational. While https://water.weather.gov/ was used for AHPS, NWPS will be implemented using the following URL, https://water.noaa.gov. The application currently present at https://water.noaa.gov will be replaced when NWPS is implemented. To support this transition, AHPS will continue operating for 60 days after NWPS is operationally implemented. After this time, all users will be redirected to https://water.noaa.gov. Thank you for your close partnership with the NWS. We look forward to continuing to work with you as the NWS transforms into a more nimble, flexible, and mobile agency providing essential mission services to you and others.
