Southeast storms: Triple-threat storm is potentially bringing more strong winds, tornadoes and flooding to Southeast

More than 46 million people were under some level of threat for severe weather Wednesday across much of the Southeast and parts of the southern Appalachians, with severe thunderstorms, damaging winds, several tornadoes and large hail possible, the Storm Prediction Center said.

The day’s highest threat — a level 3 of 5 — exists for about 13.6 million of those people, in parts of Alabama, Tennessee, far western North Carolina and Georgia, including the Atlanta area, according to the prediction center.

A flood watch also is in effect for parts of central, east-central and southwest Georgia until Thursday morning, because heavy rain could flood already-high rivers and creeks and lead to flash flooding, the National Weather Service said.

Conditions for the Southeast will begin to deteriorate as storms pop up as soon as the late morning, with storms becoming more consistent in the afternoon and continuing into the evening and early Thursday morning, CNN meteorologist Rob Shackelford said.

The storm system comes as parts of the region are still in recovery mode from recent consecutive severe weather events, including tornadoes and treacherous thunderstorms.

Monday and Tuesday brought a double-whammy of severe storms and dozens of tornado reports across Texas, Georgia, South Carolina, Mississippi and Alabama — downing trees and power lines as well as damaging homes and businesses.

The storms Tuesday killed at least one person in Georgia and another person in Texas, local officials said.

Strong storms rolling through the South kill 2, bring tornadoes and damaging winds

A man in East Texas was killed when a tree fell on an RV in the community of Whitehouse, the Smith County emergency management coordinator said.

Another person died in Bryan County, Georgia, as severe weather swept through the area, local officials said. The county, which is near Savannah, declared a state of emergency due to the impacts of a tornado and set a curfew through early Wednesday morning, officials said.

An EF-2 tornado went through Johnson County, Texas, south of Fort Worth on Monday evening, the National Weather Service said. The NWS also confirmed an EF-1 tornado in Collin County and an EF-0 tornado in Johnson County.

A preliminary survey found four EF-1 tornadoes hit Mississippi on Tuesday, the NWS said.

Storm’s path across South

As the storm makes its way across the battered South, different areas will feel its effects at different times.

Beginning Wednesday around 10:30 am, the Atlanta metro area and the remainder of Georgia can expect to see the strongest possibility for tornadoes, damaging wind gusts and large hail, Shackelford said. These threats are expected to impact the state through midnight.

Later Wednesday, Nashville and parts of Alabama — including Montgomery and Birmingham — are also under the same triple-threat from 1 to 11 pm

As for the Carolinas, the greatest threats are tornadoes and damaging winds, with less of a possibility for hail compared to their neighbor states — though it can’t be ruled out.

Charleston, South Carolina, can expect to see severe conditions beginning around 6 pm through early Thursday. Meanwhile, Charlotte and Raleigh in North Carolina may potentially see severe storms begin around midnight, with improvements by 7 am Thursday.

Correction: An earlier version of this story overstated the number of people under the day’s most severe weather threat level. About 13.6 million people live in the area with that threat level.
