The Cheyenne Office of the National Weather Service says potentially heavy rain this week could pose flooding problems in southeast Wyoming.

The agency posted the following on its website:

For folks in southeast Wyoming and Nebraska Panhandle, a heads up on a possible heavy rain event! Looks like we are going to see widespread to numerous showers and thunderstorms Wednesday and Thursday this upcoming week. Storms are going to be capable of producing heavy rainfall. The ground could probably take a lot of rain right now, but areas that receive multiple rounds of heavy rainfall stand the risk of experiencing flash flooding. A Marginal Risk area for flash flood potential has been identified for parts of southeast Wyoming and Nebraska Panhandle for both Wednesday and Thursday. Stay tuned for later updates in the forecast as we get closer to these days.
