These online interactive maps help emergency managers and decision-makers visualize where inundation will affect their communities. When flood forecasts are released by the National Weather Service, officials have the option to refer to these maps and scroll through the different river flood stages to see how inundation could impact local roads, building infrastructure, and resources. Users are then able to make better informed decisions on bridge and road closures, as well as evacuations.
- Provides National Weather Service flood forecasts in a visual format
- Allows users to scroll through inundation levels to visualize the impacts for various river flood stages (e.g., minor, moderate, major).
Note: Not all river forecast points have flood inundation maps available. The NOAA National Weather Service has a program in place to work with partners to continue to create flood inundation maps.
