CNN —  

The Southern severe weather streak continues Thursday with yet another round of extreme weather possible a day after storms killed at least six people in Texas, Oklahoma and Louisiana.

Hundreds of tornadoes have been reported across the eastern half of the US in April, most occurring across the Deep South.

A tornado that touched down Wednesday evening in southern Oklahoma killed two people and injured a number of others, according to officials.

Several vehicles were thrown into trees and there was damage to two steel manufacturing companies, Robert Chaney, director of Marshall County Emergency Management, said.

In Polk County, Texas, a tornado produced by a strong supercell thunderstorm killed three people and injured 20 to 30 others, according to county officials. A disaster declaration issued after the county was hit said there was significant damage to residential structures, commercial structures and public infrastructure.

That thunderstorm moved across Texas, Louisiana, and Mississippi. A woman was killed in Woodworth, Louisiana, during Wednesday evening’s storms. During the storm’s journey, a tornado warning was active at various periods across all three states. In total the cell covered approximately 240 miles.

A supercell is a thunderstorm that can last for several hours and have a high tendency to produce severe weather, including damaging winds, very large hail, and sometimes weak to violent tornadoes, according to the National Weather Service.

The service will have to determine exactly how many tornadoes the storm could have produced across the three states.

The preliminary number of tornadoes reported from Wednesday morning through Thursday early morning is 25.

There were at least 51,716 outages reported in Mississippi and 36,974 in Louisiana Thursday morning, according to poweroutage.us.

What’s expected Thursday

The weather service’s Storm Prediction Center says there is an “enhanced risk” – level 3 out of 5 – of severe weather in parts of northern Florida, southern Georgia, and far southern South Carolina.

Risks include tornadoes and severe wind.

A lesser risk of severe weather exists Thursday elsewhere in those states, as well as in parts of Louisiana, Mississippi and Alabama.

CNN Weather

Storms were hitting parts of Alabama and Georgia on Thursday morning and should race across Georgia and Florida through the rest of the afternoon.

A second wave of storms could arrive Thursday afternoon and evening, according to forecast models.

For the second wave, hail and damaging winds could hit, especially in parts of southeastern Mississippi and southern Alabama, the Storm Prediction Center says.

Flooding is an additional threat

The flooding potential will be higher with this round of storms because many of the locations that will see rain are already saturated from the last rain event a few days ago.

One to 3 inches of rain per hour is possible across parts of Alabama and Georgia, increasing to 2 to 3 inches per hour across eastern South Carolina.

Expect flash flooding and ponding on the roadways for these areas.
