The high level threat covers 3 million people, and in all, about 45 million people are under a severe weather threat from the storms and could see tornadoes, large hail and damaging winds. Adding to the concern is that nighttime tornadoes can be more dangerous given that people are sleeping and may be unprepared to take immediate shelter.
Two of these tornado watches were deemed a “Particularly Dangerous Situation,” or PDS, which is issued when the forecaster has high confidence that multiple strong or violent tornadoes (EF2 or higher) will occur in that area. One PDS is active in parts of Louisiana, Arkansas and Mississippi, while another PDS is active in central Mississippi and Alabama.
Individual supercells will begin to develop ahead of that main line of storms from central Mississippi into central Alabama. This will be the most dangerous part of the outbreak, the center said, as these storms typically have the greatest potential to produce long-track, intense tornadoes.
The main line of storms is then expected to continue eastward through Mississippi, Tennessee and Alabama through the evening. It will eventually reach Georgia in the overnight hours and then the Carolinas on Thursday.
Possible tornadoes spotted
Severe conditions and potential tornadoes have already been reported in the Southeast.
Josh Pate shot video of a thunderstorm Wednesday afternoon as it crossed US Highway 82 near Billingsley, Alabama, which is about 28 miles northeast of Selma.
The video “shows a rotating thunderstorm and a potential tornado forming,” said CNN meteorologist Brandon Miller.
A confirmed “large and extremely dangerous” tornado was spotted near Shelton State Community College just south of Tuscaloosa at 2:45 p.m., according to the National Weather Service in Birmingham, Alabama. The storm is moving northeast at 30 mph and has previously produced damage and potential injuries in Moundville, according to the National Weather Service.
A possible tornado that touched down earlier Wednesday in Wayne County, Mississippi, caused no reported injuries but reportedly damaged two homes and destroyed three chicken houses, according to Angela Atchison of Wayne County Emergency Management. There are also some roads that are blocked due to debris that officials were working to remove.
Authorities warn of “life-threatening” event
The areas threatened Wednesday are no strangers to the danger. The last level 5 risk for Birmingham and Tuscaloosa in Alabama came on April 27, 2011, in an outbreak that featured the most tornadoes in one day, more than 170, and killed more than 300 people, the deadliest tornado day in 75 years.
“Projections are showing that this will likely be a widespread event, with some of the most severe weather anticipated late Wednesday night into early Thursday morning,” Ivey said in a statement.
“Please make preparations now in the event your area is impacted in some way. I will continue keeping a close eye on the system and encourage every Alabamian to do the same,” the governor added.
Other officials also urged residents of the state to prepare.
