• The National Oceanic and Atmospheric Administration (NOAA) has announced the restoration of National Water Model-derived flood maps for Alaska.

Impact & Risks

The restoration of flood maps in Alaska is a significant step for communities in the region, providing them with better tools to anticipate and respond to potential flooding events. With 60% of the U.S. population now covered by flood inundation mapping services, the risk of unpreparedness during flood events is reduced. However, some areas in Alaska still await resolution for complete flood mapping coverage, leaving certain regions potentially vulnerable.
