(CBS News) -- Residents across the Midwest and South are trying to get back on their feet following devastating storms that swept across the region on Wednesday. Several tornadoes hammered a swath of the U.S., killing at least 12 people and destroying entire towns.
In Tenn., at least three people were killed. Authorities say 50 homes in neighborhoods nearby Crossville were damaged and at least five were destroyed.

One twister was so big it was labeled an EF4 - the second highest rating given to tornadoes. Scientists say the tornado was 200 yards wide with winds up to 170 miles per hour.
In Harrisburg, Ill., the local newspaper's headline reads, "We will rebuild." The twister damaged 300 homes and businesses there. Already, damage estimates are in the tens of thousands of dollars.
Tammy Risley, a Harrisburg resident, told CBS News, "The sirens went off and...everything just came through. It was like my house inhaled and just let it out."
Risley said she felt like she cheated death. "I had a guardian angel watching over me," she said.
Now she's not sure what to do -- or where to go. Some people in Harrisburg took shelter with the Red Cross.
On Wednesday, Gov. Pat Quinn (D-Ill.) declared Harrisburg and the surrounding counties a disaster area.
"It's amazing how some businesses and families -- their homes are intact, and across the street it's completely obliterated," said Quinn.
