Flood Risk for the U.S. Midwest and Plains

The melting of snow packs combined with spring rains present significant flood risks to much of the Northern U.S. each year, usually starting around March. This year, NOAA has issued advisories and warnings to areas stretching from Montana down to Missouri. Areas along major rivers, such as the Mississippi, are at even higher risk. This image plots the areas of "above average" and "high" risk for flooding through mid-March. An updated advisory will be provided around March 17th. The data used in this imagery is a seasonal forecast model; actual river height conditions can be monitored here.
