Flash flood watch upgraded to warning in Johnson County
A slow-moving, heavy rainstorm is expected to continue to produce excessive runoff, prompting the National Weather Service to place Johnson County under a flash flood warning through 4:30 p.m. today.
Similar warnings also have been posted for Wyandotte and Leavenworth counties in Kansas.
At 10:27 a.m. Monday, National Weather Service Doppler Radar indicated slow-moving thunderstorms with heavy rainfall across the area.
The National Weather Service warned that excessive runoff from heavy rainfall will cause flooding of small creeks and streams, urban areas, highways, streets and underpasses, as well as other drainage areas and low-lying spots.
Do not drive your vehicle into areas where the water covers the roadway. The water depth may be too great to allow your car to cross safely. Report flooding to the nearest law enforcement agency so that appropriate action can be taken to close flooded roadways. Law Enforcement officials will relay your report to the National Weather Service in Pleasant Hill.
