NOAA’s National Weather Service has launched a new website: The National Water Prediction Service. This new hub for water data, products, and services combines local and regional forecasts with water data and new national level capabilities, such as flood inundation maps and the National Water Model.

Key features integrated into the National Water Prediction Service website include:

• A new, dynamic and seamless national map with flexible options and expansive layers available to help analyze water conditions anywhere in the country.
• Improved hydrographs that are frequently updated, depict water level observations over the past 30 days, and provide river flood forecasts up to 10 days in advance. 
• The National Water Model, which provides 24-hr. coverage, seven days a week hydrologic forecast guidance along 3.4 million river miles across the U.S., including river segments, streams and creeks that have no river gauges.
• Real-time, comprehensive flood inundation maps, which are being implemented in phases, will cover nearly 100 percent of the U.S. by October 2026.
• An application programming interface (API) has been added to the traditional geographic information system (GIS) data, which will allow customers to flow water information into their own applications and services.

The National Water Prediction Service website provides tools that deliver actionable hydrologic information across all time scales to address the growing risk of flooding, drought and water availability, and enables partners and the American public to make smart water decisions.
