Story has been updated to include Marion County

Dickinson and Marion counties have been included in a flash flood watch issued by the National Weather Service (NWS).

The watch will be in effect from Saturday evening through Sunday afternoon.

Thunderstorms capable of producing heavy rainfall are expected to develop across northeast and east central Kansas Saturday evening and continue into the day on Sunday. Rainfall amounts of 2 to 4 inches are expected with locally higher amounts possible. This amount of rainfall in a short period of time could cause flash flooding across the watch area.

NWS noted that flash flooding of rivers, streams, and low water crossing including some roadways could occur. Be especially careful at night and so not drive through flooded roadways.

A flash flood watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.

You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.
