In an advisory, the NWS warned that portions of the three states are under flash flood warnings due to expected thunderstorms that will bring heavy rain.

The heavy rain came after severe flooding in the area killed three people and damaged dozens of homes on July 8.

On Monday morning, flash floods led to a water rescue at a trail in south Overland Park, where one woman died. The woman, identified as 62-year-old Anupama Vaidya, had been walking on a trail at Negro Creek when flash flood waters swept her away, officials said.
