This article discusses the impact of increasing amounts of rainfall in the Midwest – it’s not good.
Minnesota is getting wetter. Over the last 100 years, the state has seen more storms that produce heavy rainfall, and its strongest storms have grown more intense. One of the more dramatic changes is the increasing number of “mega-rain” events — rainstorms during which at least 6 inches of rain falls over at least 1,000 square miles and the center of the storm drops more than 8 inches of rain. Minnesota has had 11 mega-rains since 1973,1 and eight of them have come since 2000. Two mega-rains swept through in 2016, which is only the third time the state experienced more than one mega-rain in a year. (It also happened in 1975 and 2002.)
