National Weather Service hydrologists predict moderate flooding in parts of southern Wisconsin, southern Michigan and portions of Illinois, Indiana, and Iowa as a result of the current snowpack and the deep layer of frozen ground coupled with expected seasonal temperatures and rainfall. At-risk is the Mississippi River and the Illinois River, as well as many smaller rivers in these regions. Small streams and rivers in the lower Missouri basin in Missouri and eastern Kansas have already experienced minor flooding this year, and the threat of moderate flooding will persist through the spring.
Minor flooding is likely in the northern Rockies, parts of the Midwest, and the Great Lakes region. Minor flooding is also possible in the Northeast, the lower Mississippi River basin, and across the entire Southeast up to Virginia, including east Texas, and parts of Arkansas, Tennessee, Kentucky, West Virginia, and the Florida panhandle. In these areas, spring flood risk is highly dependent on rainfall.
