A line of thunderstorms swept across Tennessee, ripping apart homes, destroying a campground and causing widespread flooding. A 7-year-old girl was killed early Monday when winds caused the collapse of a wall at her grandparents' home.

At least nine others died in a weekend of powerful storms that produced heavy rain, high winds and some tornado activity along an arc from Louisiana to New England. More thunderstorms moved across parts of the Great Lakes states.

The Tennessee storms late Sunday and early Monday dumped up to two inches of rain in just over an hour and delivered high winds and hail the size of golf balls.

Nearly 100 houses and farm buildings were destroyed or damaged in Giles County about 80 miles south of Nashville, including the home where 7-year-old Katie Hardman was killed.

A total of 22 people were injured, most at a campground in Hardin County where wind knocked over trees, destroying about 25 camper trailers and three campsites along the Tennessee River near Alabama and Mississippi.

In Indiana, a Sunday afternoon tornado in Marengo killed one man and destroyed at least 50 houses, police said. The twister, one of 13 in Indiana on Sunday, carried winds of up to 170 mph, the National Weather Service said.

In West Virginia, storms dumped more than four inches of rain in coalfields in the southern section of the state, killing an elderly man who was swept away by flooding and injuring his wife in Wyoming County.

In Kentucky, the Weather Service said it confirmed that a tornado damaged buildings in one Louisville-area subdivision and that another in Barnsley, Ky., destroyed a home and blew off roofs of businesses along a six-mile-long path. No injuries were reported from either tornado.

In Ohio, a man died early Monday after being struck by lightning at a campground in Lebanon, northeast of Cincinnati.

The powerful storms also were blamed for one death in Missouri on Sunday, where a man was killed by a tree that slammed onto his car. On Saturday, a tornado cut a destructive 50-mile path across northwest Missouri, killing three people and injuring four children.

High winds were blamed for two deaths in Kansas, also on Saturday.

Part of the roof of an apartment complex was torn off by a tornado that swept through the southern Indiana town of Marengo.
