Heavy Rainfall and Flash Flooding -  4/17-18/2013

Locally heavy rainfall from training thunderstorms led to flash flooding from the Ozarks, through east central Missouri and into south central Illinois.  One area that experience flash flooding was De Soto Missouri, where an 80 year old woman lost her life after driving into a flooded roadway and her car was swept downstream in Joachim Creek. 

Below is an image of the rainfall that was observed over the seven day period ending 4/19/2013.  This excessive rainfall across the Midwest and Great Lakes led to significant and in some cases record river flooding.
