Washington: As severe storms swept across South and Central America, at least 35 people were left dead and tens of thousands remained without power even as forecasters downgraded the threat to the eastern half of US.
Some storm risks remain, including the possibility of large hail, damaging winds and flash flooding in portions of the South and East Coast, National Weather Service's Storm Prediction Centre said Tuesday night.
Mississippi and Alabama-where tornadoes Monday caused widespread destruction and several deaths-were again in the bull's-eye for the worst of the forecast on Tuesday evening, CNN reported.
A number of tornado warnings expired Tuesday night in North Carolina, where forecasters say the storm was barrelling north.
Tens of thousands were without power in the South, where suspected tornadoes tore through homes and businesses late Monday.
At least 17 people were killed in Mississippi, Alabama and Tennessee on Monday.
Those deaths are in addition to 18 others reported in Arkansas, Oklahoma and Iowa from storms Sunday.
