Indianapolis, Indiana – Hoosiers could face renewed flooding concerns by Wednesday evening as a powerful storm system brings heavy rain and the potential for severe thunderstorms across much of Indiana.
According to the National Weather Service in Indianapolis, periods of heavy rain are expected Wednesday through early Thursday, with some communities potentially receiving 1 to 2 inches of rainfall or more. The greatest concern is for areas that have already experienced recent heavy rain, where saturated ground could increase runoff and flooding issues.
The threat extends across central Indiana, including Indianapolis, Lafayette, Bloomington, Muncie, Terre Haute and Vincennes. Forecast data shows a high probability that many locations will exceed 0.50 inch to 1 inch of rainfall, while localized totals above 2 inches remain possible under stronger thunderstorms.
Flood-prone roads, low-lying areas, creeks and urban drainage systems could become overwhelmed if storms repeatedly move across the same locations. Motorists should be prepared for ponding water during the Wednesday evening commute and overnight travel.
Residents are encouraged to clear storm drains, charge electronic devices and have multiple ways to receive weather warnings. Drivers should never attempt to cross flooded roadways, even if water appears shallow.
The heavy rain threat arrives alongside a separate risk for severe thunderstorms Wednesday, creating the possibility of damaging winds and additional weather-related impacts. More watches and warnings may be issued as confidence increases in the location of the heaviest rainfall.
