Evansville, Ind. ? Just eight days after a deadly tornado struck southwestern Indiana, another strong storm system rolled across the nation’s midsection Tuesday, producing funnel clouds in at least three states.

The National Weather Service issued tornado watches and warnings for the Evansville area, as well as for parts of Tennessee, Missouri, Arkansas, Illinois and Kentucky.

Funnel clouds were sighted in Indiana and Illinois, but it was unclear how many remained aloft or touched the ground. There were no immediate reports of serious injuries.

Andy Zirkle, a spokesman for the Indiana Emergency Management Agency, said the severe storms destroyed at least seven homes in the southern part of the state.

“The wind was just really, really ferocious,” said Julie Wilz, a desk clerk at the Red Roof Inn in Montgomery, where about 15 people took shelter during the storm.

In western Tennessee, a funnel cloud reportedly touched down, damaging an undetermined number of homes and buildings in Henry and Weakley counties.

“Numerous homes there were damaged, some completely destroyed,” said Faye Scott, spokeswoman for the Henry County Sheriff’s Department. “It’s major destruction.”

Ann Wiese finds some belongings in the rubble of her grandmother's home that was destroyed by a weekend tornado Monday in Stratford, Iowa. Storms continued to roll across the Midwest on Tuesday, causing damage to numerous homes and businesses in Kentucky and Indiana.

The tornado made a direct hit on Henry County’s emergency management center, forcing authorities to relocate to another building to handle the disaster, County Mayor Brent Greer said.

The county medical center treated 13 people with injuries, mostly cuts and bruises, hospital spokeswoman Sandra Sims said.

The storm ripped the roof off the main shop at the county highway department, destroyed two smaller shops and damaged a furniture manufacturer next door, Greer said.

In neighboring Weakley County, up to seven homes and trailers were damaged or destroyed.

The National Weather Service could not immediately confirm the tornados.

Meteorologists said a cold front moving east and colliding with warm, unstable air was producing severe thunderstorms across the central Mississippi and lower Ohio valleys.

Dan Spaeth, a weather service forecaster, said Tuesday’s conditions were similar to those that produced the tornado on Nov. 6 that caused 41 miles of damage from Kentucky into the Evansville area and killed 23 people.
