The death toll from a swarm of Memorial Day weekend thunderstorms and tornadoes (search) stood at 10 as residents of the South and Midwest struggled with power outages, flooding and debris-logged streets.

More thunderstorms pounded parts of the South on Tuesday, and the National Weather Service (search) said radar detected two possible tornadoes during the night in Texas. Storms produced heavy rain Monday from Louisiana to New England, following the weekend's violent weather that ravaged Marengo and other parts of the Midwest.

Gov. Joe Kernan (search) surveyed the damage from a helicopter Monday, a day after the storms that destroyed dozens of homes, and said Marengo "just got clobbered." The weather service estimated the tornado that struck the town of 800 people had wind up to 170 mph.

Two Indiana National Guard units were expected to arrive Tuesday in Marengo, about 35 miles northwest of Louisville, Ky., to move heavy debris, said Lt. Col. Larry Powers, a Guard spokesman.

Kernan extended a disaster emergency he issued last week for the entire state.

Crews used backhoes and tractors Monday to clear Marengo's streets and yards. Power company workers erected new utility poles, and residents used chain saws to cut up scores of fallen trees, including one that mangled playground equipment at the elementary school.

"Everything we own is gone," Amber Terry said as she picked through the wreckage of her mobile home, which was smashed into a neighbor's house about 20 feet away. She said she, her husband and two young children would move in with her parents.

"Just pick up and start over," Terry said.

One man died in Marengo when the twister flipped his mobile home.

Nearly 100 homes and farm buildings were destroyed or damaged early Monday in Tennessee's Giles County, about 80 miles south of Nashville. A total of 22 people were injured in Hardin County — most at a campground where wind knocked over trees, destroying some 25 camper trailers.

The weather service said it believed wind of more than 60 mph was to blame for the damage, although forecasters didn't rule out a tornado.

A 7-year-old Tennessee girl died after a wall collapsed in her Giles County home.

In West Virginia, storms dumped more than 4 inches of rain in coalfields in the southern section of the state, killing an elderly man who drowned while pumping water out of his basement, possibly after a heart attack or being overcome by fumes.

Gov. Bob Wise declared a state of emergency in that county and two others Monday, after declaring emergencies in seven other counties Friday.

"We've got hundreds of homes right now with major damage, hundreds more that have suffered some damage," Wise said Tuesday on a morning news program. "We haven't been able to ascertain yet all the damage, but we know that it's going to be very, very great."

In Kentucky, the weather service said it confirmed that a tornado damaged buildings in one Louisville-area subdivision on Sunday, and another in Barnsley destroyed a home and blew off businesses' roofs along a six-mile-long path. No injuries were reported.

An Ohio man was killed early Monday by lightning at a campground in Lebanon, northeast of Cincinnati. One man was killed by a falling tree Sunday in Missouri. On Saturday, a tornado in northwest Missouri killed three people and injuring four children.

High wind was blamed for two deaths in Kansas, also on Saturday.
