It's April Fool's Day, but the National Weather Service (NWS) Indianapolis said they were not joking about more hazardous weather being on the way.
NWS has already issued a flood watch for the southern half of the state and a hazardous weather outlook to the north.
The watch remains in effect through Sunday and officials remind people to have multiple ways to receive warnings as several storm waves make their way across the Hoosier State.
"Heavy rainfall is possible from late Wednesday through Saturday night due to multiple wave passages," the flood watch notes. "Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Extensive street flooding and flooding of creeks and rivers are possible."
Flash flooding will be possible Wednesday night into Thursday morning with significant river flooding potentially developing late this week into the weekend.
The primary threat of the storm starts at 6 p.m. Wednesday with a threat of hail going until midnight. There's a moderate risk of flooding, an enhanced risk of wind and possible tornadoes, and a slight risk of hail.

Generally a flat area of land adjacent to a river or stream is more prone to flooding during periods of heavy rain. The primary rivers and streams in Indianapolis and the surrounding Marion County are White River, Fall Creek, Eagle Creek, Pleasant Run, Little Eagle Creek, and Pogue's Run.
The City of Indianapolis has this floodplains map, launched in 2015, that is consistently updated to show waterways.
FEMA also has a map where you can see if your area is prone to flooding. Add your address, click to pinpoint the map and follow the instructions on their map to get a detailed report on your area.
🚨 Indiana Weather Alerts: Warnings, Watches and Advisories.
Flooding is the main cause of deaths during thunderstorms, and the Centers for Disease Control and Prevention says more than half of all drownings occur when a vehicle is driven into hazardous floods. NWS advisers commuters to never drive around barriers blocking flooded areas. Roads may have collapsed underwater and the holes would remain unseen to drivers.
Even just 12 inches of rushing water can carry away most cars and 2 feet can carry SUVs and trucks.
It's never safe to drive or walk into flood waters.
