Storms wreck Ind. towns, flatten houses elsewhere (AP) - Powerful storms stretching from the Gulf Coast to the Great Lakes flattened buildings in several states, wrecked two Indiana towns and bred anxiety across a wide swath of the country in the second powerful tornado outbreak this week. Widespread damage was reported in southern Indiana, where Clark County Sheriff's Department Maj. Chuck Adams said the town of Marysville is "completely gone" and extreme damage was reported in nearby Henryville. Just east of there in Kentucky, an apparent tornado flattened a volunteer fire station. Dozens of houses were also damaged in Alabama and Tennessee two days after storms killed 13 people in the Midwest and South. No fatalities had been reported in the latest round of storms that were expected to threaten tornadoes late into Friday. Thousands of schoolchildren in several states were sent home as a precaution, and several Kentucky universities were closed. The Huntsville, Ala., mayor said students in area schools sheltered in hallways as severe weather passed in the morning. At least 20 homes were badly damaged and six people were hospitalized in the Chattanooga, Tenn., area after strong winds and hail lashed the area. To the east in Cleveland, Blaine Lawson and his wife Billie were watching the weather when the power went out. Just as they began to seek shelter, strong winds ripped the roof off their home. Neither were hurt. "It just hit all at once," said Blaine Lawson, 76. Didn't have no warning really. The roof, insulation and everything started coming down on us. It just happened so fast that I didn't know what to do. I was going to head to the closet but there was just no way. It just got us. "Most of the children were in schools so they were in the hallways so it worked out very well," said Huntsville Mayor Tommy Battle. Forecasters at the National Weather Service's Storm Prediction Center in Oklahoma said they were bracing for what could be a potent tornado outbreak. At least 10 homes were damaged in a subdivision in Athens, Ala.
