What the reports say
Written by National Weather Service staff at the time of the event · public domain
Widespread heavy rains of 8 to 10 inches caused flooding of numerous county roads across Northern Sedgwick County. One fatality occurred to the south of the town of Sedgwick, near the 11200 block of North West, when a stalled motorist apparently attempted to flee his vehicle and was swept into the ditch by the fast moving water and drowned.
Nine to twelve inches of rainfall during the morning commute hours causing widespread street flooding of roadways up to 2 to 3 feet deep on the West side of the City of Wichita. Law enforcement officials reported 150 people were rescued from vehicles or evacuated because of the high water. 114 homes reported some type of surface flooding due to the heavy rainfall and sewers and sump pumps backed up into 141 more homes. This unprecedented amount of rainfall mainly fell during a five hour period, reminding some of the Halloween Flood of 1998. The large amount of rainfall caused the Cowskin/Calfskin Creek to once again come out of its banks, flooding homes in the Dells and Hidden Lakes Subdivision. 35 people were evacuated from the Park West Retirement home along the banks of the creek. Calls about stalled vehicles overwhelmed towing businesses across the city.
Significant flash flooding occurred in the town of Mulvane, Kansas. Three buildings in downtown were flooded. Styx Creek ran out of banks and caused extensive flooding to homes along it. A water rescue occurred in town due the high water. A woman is safe after fast-moving water swept her vehicle into a ditch. She had been standing on top of her car and holding onto a tree while she was on the phone with 911.
