A major flash flood event engulfed many locations across south central Kansas.  During the evening of August 19th a strong cold front pushed across central and eastern Kansas. Storms developed along this front and tracked off to the southeast during the evening hours. With a very moist atmosphere in place, these storms produced rainfall rates around 2-3 inches per hour. Several rounds of storms affected southern Sedgwick and southern Butler counties which resulted in rainfall in the 5 to 7 inch range with most of it falling in around 2 hours. This lead to significant flash flooding, especially near Mulvane and south of Rose Hill. Numerous water rescues took place with homes also evacuated.
