#Flooding that spread across parts of #Iowa, #SouthDakota & #Minnesota this past weekend is forecast to worsen Mon & Tues as rivers continue to rise. Meteorologists warn that any additional #rain from possible #thunderstorms could extend or heighten the risks.
The #floods are the product of torrential #rain across parts of the upper Mississippi River basin since Thurs, dumping totals of 10”–18” of rain…. Soils were already saturated from months of wetter-than-avg conditions before #storms fueled by intense Gulf of Mexico moisture lingered over the region Thurs–Sat.
That sent runoff into #streams & #rivers & overwhelming #levees…. Rivers are expected to crest Tues or Wed at moderate to record #flood stages.
