The National Weather Service issued a tornado watch until 10 p.m. on Tuesday for Monroe County and parts of Indiana, Kentucky and Ohio.
A tornado watch means that weather conditions are appropriate for a tornado to form, but no tornado has been observed. If a tornado does form, the alert will be upgraded to a tornado warning.
In the event of a tornado warning, residents should immediately seek shelter in the lowest floor of a sturdy building away from windows.
The NWS forecasts that wind gusts of up to 75 mph and hail up to two inches in diameter are possible.
Bloomington is also under a flood watch until 8 p.m.
Monroe County residents can monitor the forecast through local weather channels and NWS live trackers.
