(CNN) — A widespread weather system across the southern United States has left a trail of devastation in Louisiana, killing at least three people and injuring dozens as violent tornadoes tore down, toppling homes, turning debris into projectiles and turned off the power.
According to the Louisiana Department of Health, the deaths from the storm-related incidents included a 56-year-old woman who died after a tornado struck her home in the Kelowna area of St. Charles Parish.
In addition, a boy and his mother were found dead after a tornado destroyed their home Tuesday in the northwest Louisiana community of Keithville, the Caddo Parish Sheriff’s Office said. The bodies of the mother and son were found hours away from where their home used to be, officials said.
Several communities in Louisiana reported devastation, with roofs ripped off, homes destroyed, streets strewn with debris, and cars overturned. According to PowerOutage.us, more than 50,000 customers went down power lines in Louisiana and Mississippi on Wednesday night without power. The number had come down to less than 15,000 in the early hours of Thursday.
According to the Storm Prediction Center, there were at least 49 reports of tornadoes in Louisiana, Mississippi, Texas, Alabama and Florida on Tuesday and Wednesday. More tornado reports are likely to come as surveyors continue to confirm damage.
And the danger is not over yet. According to CNN meteorologist Robert Shackelford, more than 15 million people could see severe weather Thursday in parts of Florida, Georgia and the Carolinas.
As of 9 a.m. Thursday, more than 1.5 million people were on a tornado watch in southeast Alabama, northern Florida and southern Georgia. Strong tornadoes are still possible, as well as quarter-size hail and powerful wind gusts of up to 70 mph.
Heavy storms across Louisiana and throughout the Southeast are part of a larger system that has also brought snow storms to the north-central US.
By Thursday, the storms are expected to weaken slightly, but there is a threat of severe weather across much of Florida, coastal Georgia and the coastal Carolinas. Shackelford said damaging winds, large hail and isolated tornadoes could occur in cities including Tampa, Orlando, Jacksonville, Savannah and Charleston.
