Flooding

Over 60 water rescues took place across the Kansas City metro area, and at last count, 62 of those water rescues occurred overnight on the 21st into the 22nd in Kansas City, MO. Indian Creek at State Line Road broke the record that only stood for about 3 weeks, when it eclipsed the 28 foot mark for the first time in that location's recorded history, which goes back to 2004. This flooding was caused by a period of roughly 6 hours that produced 5 to 7 inches of rain, with some locations seeing 8 to nearly 10 inches.
