NOAA Restores Flood Maps for Alaska and Expands Inundation Mapping Services
NOAA Restores Flood Maps for Alaska and Expands Inundation Mapping Services
US · Published Sep 1, 2026
The National Oceanic and Atmospheric Administration (NOAA) has announced updates to its National Water Prediction Service (NWPS).
Flood maps derived from the National Water Model have been restored for Alaska, with one remaining map still pending resolution.

Impact & Risks

The restoration of flood maps in Alaska and the expansion of Flood Inundation Mapping services to 60% of the U.S. population significantly enhance the ability to predict and prepare for flood events. These tools are critical for emergency management agencies, urban planners, and communities in flood-prone areas. The updates aim to reduce the risks associated with extreme precipitation and flooding, which can lead to property damage, displacement, and loss of life. However, one flood map in Alaska remains unresolved, which may leave certain areas without updated predictive capabilities.
