Indiana's Department of Homeland Security says a tornado outbreak Wednesday produced at least 12 tornadoes.
Agency spokesman John Erickson says officials are still assessing the storm damage Thursday, but that the tally as of Wednesday night showed 12 tornadoes touched down in Adams, Allen, Blackford, Cass, Grant, Howard, Marion and Montgomery counties in northern and central Indiana.
Several of those tornadoes struck Howard County, where the south side of the city of Kokomo suffered extensive damage.
National Weather Service surveys Thursday should determine whether additional storm damage in other areas was caused by tornadoes or high winds in severe thunderstorms.
Authorities say between 15 and 20 people suffered injuries but none were severe.
Emergency officials and the Red Cross have set up shelters for victims of the tornadoes.
One shelter is at the Kokomo Event and Conference Center. The Indianapolis Star reports that about 200 people were being housed and fed at the center at 9 p.m. on Wednesday, hours after the storms moved through. Kokomo is about 50 miles north of Indianapolis.
Another shelter is at Walnut Elementary School in New Ross, northwest of Indianapolis.
The Indiana Red Cross regional headquarters in Indianapolis has a team of employees and volunteers working at an operations center.
