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 parts of Tennessee, Missouri, eastern Arkansas, southern Illinois and western sections of Kentucky.

A funnel cloud was sighted in Clay City in central Indiana but apparently remained aloft. Two funnel clouds were also reported in southern Illinois, but there were no immediate reports of damage.

In western Tennessee, a funnel cloud reportedly touched down, damaging an undetermined number of 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."

Tom Cooper, police chief in Paris, Tenn., told Nashville television station WSMV that 15 to 20 people suffered minor injuries from flying debris in the community about 85 miles west of Nashville.

The National Weather Service could not immediately confirm the tornado.

Flood warnings also were posted as more than 6 inches of rain fell in parts of the Ohio River Valley.

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.

The most severe damage on Nov. 6 was in a mobile home park on the eastern edge of Evansville where 19 of the victims were killed. Four other people were killed in neighboring Warrick County.

Elsewhere in the Midwest, nine tornadoes swept across central Iowa on Saturday, killing one woman.

Though severe thunderstorms and tornados are not uncommon in the fall, Spaeth said the strength of storm systems that have produced recent tornadoes suggests severe weather ahead.

"It's not usually as widespread or frequent," he said. "But if it happens once, it can happen again."
