A major winter storm is pushing east, bringing powerful winds and blizzard conditions to the north and deadly tornadoes to the South.
Here's the forecast for the week:
More tornadoes were expected on Wednesday in Louisiana, Mississippi and Alabama as the storm moves east.
The tornado threat also extended into the Florida Panhandle Wednesday night, with tornadoes possible overnight in the region.
On Thursday, severe storms and tornadoes could be possible as far east as Tampa, Jacksonville and Orlando.
This comes after at least 42 tornadoes touched down across the South since Tuesday afternoon in Oklahoma, Texas, Louisiana and Mississippi. A woman and her 8-year-old son were killed when one of those tornadoes swept through Pecan Farms, Louisiana, on Tuesday, according to local officials.
A 56-year-old woman also died after a tornado destroyed her house in the Killona area of St. Charles Parish on Wednesday, state officials said. Eight others were injured, the local sheriff said.
Officials in St. Bernard Parish, east of the French Quarter, confirmed that a tornado touched down in Arabi on Wednesday and caused significant damage.
Nearly 45,000 customers were without power Wednesday night, according to electric company Entergy.
