Storm-ravaged Hallam, Nebraska was evacuated Monday as another round of severe weather threatened.

Residents who had come to the town to try to gather scattered belongings were directed out of town by the Nebraska National Guard.

Governor Mike Johanns, U.S. Senator Chuck Hagel and officials with the Federal Emergency Management Agency were also forced to leave the town only minutes after arriving aboard a military helicopter.

The storm threats came less than two days after a tornado ravaged the town of 276 south of Lincoln.

The Saturday night tornado all but leveled Hallam.

Seventy-three-year-old Elaine Focken of Hallam, who lived alone, died when she was apparently hit by debris after being unable to reach her basement before her home was struck by a tornado. Thirty-three people in Lancaster County were treated for injuries.

Sixty-five-year-old Millie Schuster was among the Hallam residents trying to determine what belongings remained Monday in the aftermath of the storm.

Schuster was going through debris of her one-story brick home shared with her husband, Merle. They were in Lincoln when the tornado struck.

She says they will salvage what they can but there is very little. So far they found only an heirloom clock, the family Bible and clothes still hanging in a closet in the small portion of the house still standing.

She says the loss was, ``pretty tough at first, but we're alive and that's the main thing.''

More than a dozen tornadoes swept across southern Nebraska Saturday night prompting Governor Mike Johanns to declare a state of emergency.

Most of the buildings in town had been condemned or declared unsafe. Residents were evacuated to Lincoln where the Red Cross set up a staging area at Southwest High School.

Several railroad cars were knocked off their tracks in the middle of town, the remains of a 50-foot grain silo draped over them like a soggy paper cup. Pieces of twisted metal hung from bark-stripped trees and creaked in breeze.

Pat O'Brien, a commander with the Hallam Volunteer Fire and Rescue team, said it was unclear whether more than one tornado hit Hallam.

"If it was one tornado, it was a pretty big one," he said.

Lancaster County officials are operating numbers in which concerned relatives and friends can call to check on the welfare of loved ones: 402-441-6384 or 402-441-6385.
