Overnight on July 26 - 27, 2017 heavy rain caused major flash flooding across portions of the Kansas City Metro area. The rain started across northern Kansas City around 9 pm and continued to track across the metro through to the early morning hours. Most locations experienced 3+ hours of heavy rain rates approaching 1-2 inches (2.5 cm - 5 cm) per hour. The results were widespread precipitation totals of 5 to 7 inches of rain (12.7cm - 17.7 cm). This caused catastrophic flooding along several local streams, including Indian Creek in Overland Park, Kansas and Tomahawk Creek in Leawood, Kansas.

Numerous swift water rescues were carried out, with many businesses losing stock (including automobiles) that were washed away in the flood waters.
