It’s been a wet spring, and the National Oceanic and Atmospheric Administration predicts it’s going to get even wetter. According to NOAA’s U.S. Spring Outlook issued last month, nearly two-thirds of the lower 48 U.S. states face a greater risk for flooding through May, with the potential for major or moderate flooding in 25 states.
Sections of the nation such as the upper Mississippi and Missouri River basins that include Nebraska, Minnesota and Iowa have already been whipsawed by floods and are bracing for more flood waters, some of which may be among the worst flooding ever in those areas. Floods have been among the worst tragedies and natural disasters in our nation’s history.
The factors behind the flooding are rapid snow melt combined with heavy spring rain and late season snowfall in areas where soil moisture is high.
The Upper Mississippi Valley, the Plains of the Missouri River Basin, Red River of the North, and the Great Lakes basins have had higher than normal snowpack, and ice jams are making the flooding worse. Communities and farms in the Missouri River basin have sought state and federal funds to deal with the onslaught of water.
NOAA said in its report that excess water may extend flooding to other areas that have not experienced it, such as the mid-section of the United States.
To determine what areas may be subject to major flooding events this spring, 24/7 Wall St. reviewed the National Oceanic and Atmospheric Administration’s 2019 National Hydrologic Assessment, released on March 21, 2019.
