A powerful spring storm unleashed tornadoes and winds strong enough to peel the roofs from homes in the Deep South and heaped snow and ice on the Midwest, killing three people and leaving thousands without power.

Emergency officials said one person was killed by a tornado in Mississippi. In Missouri, a utility worker repairing power lines was electrocuted, and a woman in Nebraska died when she tried to trudge through a blinding snowstorm from her broken-down car to her house a mile away.

Golf-ball and baseball-sized hail pelted parts of Georgia and the Carolinas.

High winds knocked down trees and power lines across the Southeast, though the storm had mostly moved out of the region by Friday morning. Sleet and freezing rain made driving treacherous in northern New York, where several schools closed and scores of others delayed the start of classes.

In Mississippi, Emergency Management Agency spokesman Greg Flynn said that one person died and 10 people were injured after a tornado struck Kemper County in the far-eastern part of the state. He said everyone had been accounted for, with the focus now shifting to damage assessment and cleanup.

Charlotte Conner, 47, and her mother were in a small, concrete block apartment on her family’s property in Shuqualak, an eastern Mississippi town of 500 people, when a tornado mowed it to the ground. The building, an old country store converted to an apartment, was reduced to a heap of broken concrete blocks and boards.

Conner said in a telephone interview Friday that she grabbed her mother’s hand to keep the woman from being sucked out of the house. The two women had injured knees, scratches and bruises, and Conner had to get five stitches in her chin.

“I feel like I’ve been run over by an elephant and a train, but we’re alive,” Conner said. “It was just the hand of God that kept us safe.”

Conner’s aunt, Cindy Moore, 56, worried that the two women had been killed when she saw the roof of the concrete block building they were in hung in trees across the street in Shuqualak and their belongings scattered in the yard.

In Alabama, officials confirmed a tornado with winds up to 120 mph blew through a rural stretch east of Montgomery. No one was hurt in the state, though damage was scattered across several counties.

Friday morning light showed there wasn’t much left of the two-story home that 41-year-old James Brooks shared with his wife, Billieanne, and their three children.

With the lights out and the storm bearing down on the home, Brooks said he went to the kitchen to get a candle. Loud thunder rumbled continuously, and he dove to the floor.

Then, he said, “The house exploded.”

Much of Brooks’ roof was missing afterward, his wooden workshop was gone and linens hung across bare rafters. His two boats were damaged along with two cars and two trucks; the trampoline was in the neighbor’s yard.

The system first swept across the nation’s midsection Wednesday night and pummeled portions of Missouri. An EF-2 tornado, which generally carries winds of 113 mph to 157 mph, appears to have damaged dozens of homes in the St. Louis suburb of Hazelwood and more than 23,000 homes and businesses lost power, the National Weather Service said Thursday. A utility worker for Ameren Missouri was electrocuted while helping to repair damage, the company said.

In the upper Midwest over the past couple of days, heavy, wet snow, ice and wind have left thousands of homes and businesses without power. Some rivers topped their banks in Michigan, forcing officials to close roads and some residents to evacuate their homes.
