On average, July is one of the wetter months in Kansas. Coupled with wet conditions in June, flooding is a possibility. July 12th marks the anniversary of one of the worst floods on the Kansas River. June of 1951 was the wettest month for Kansas, surpassing even July of 1993. During the four days preceding the flood much of eastern Kansas and western Missouri received more than ten inches of rain. Flooding in the Midwest claimed 41 lives, left 200 thousand persons homeless, and caused a billion dollars property damage. Kansas City was one of the areas that were hardest hit. The central industrial district sustained 870 million dollars property damage.
