Severe thunderstorms that could produce hail or isolated tornadoes are expected across Indiana for much of the day today.
The National Weather Service has issued a flash flood warning until 9:30 a.m. for Clay, northern Owen and southern Putnam counties.
Vigo County is in a flash flood warning until 7:30 a.m.
The thunderstorms are part of a wave of severe weather sweeping across the Midwest.
The AP reports baseball sized hail damaged homes and cars in Nebraska and Iowa yesterday.
The National Weather Service said reports of extensive hail damage and flooding trickled in as storms pushed into Nebraska and moved into neighboring Iowa, where winds of up to 85 mph were recorded. Up to 4 inches of rain was expected in parts those states, which were the hardest hit. The storm also tracked across parts of Kansas, Missouri, South Dakota and Illinois.
"This is one of these days we can't let our guard down," said Bill Bunting, forecast operations chief at the Storm Prediction Center in Norman, Oklahoma.
Bunting said several trained spotters reported tornadoes in central and southwest Iowa, and at least one report came in from southwest Kansas. Reports will not be confirmed until damage can be assessed Wednesday morning.
