A severe storm was moving east across the central and southern United States on Wednesday, a day after it carved a destructive path across North Texas that downed power and ripped roofs off buildings.

More than 150,000 customers in Texas were without power as of early Wednesday, after the storm’s strong winds pummeled the region. Nearly a dozen counties in the Dallas-Fort Worth area were affected. It was not clear how many power outages were directly caused by the storm, but the authorities in some areas closed schools and ordered residents to evacuate.

The storm, which forecasters have said is unusually strong for March, was expected to strengthen as it moved east. The National Weather Service said it would bring damaging winds, blizzard conditions and chances of localized flash flooding.

Warnings were in place on Wednesday for blizzards in the Great Plains and severe storms across the South, with damaging gusts, hail and possible tornadoes forecast from eastern Oklahoma to Alabama and in western parts of Florida.

The system was also expected to affect much of the East Coast. Severe thunderstorms are possible across the eastern Carolinas and into southeast Virginia, according to the Weather Service’s Storm Prediction Center.
