Tornado Emergency Issued As Violent Twisters & 70 Mph Gusts Threaten Highways Across Multiple Southern States

A Tornado Emergency, the highest-tier warning the NWS (National Weather Service) issues, is active across central Mississippi tonight, Thursday, May 7, 2026, after a confirmed violent tornado tracked east of Meadville at 50 mph and a second tornado developed near Brookhaven along I-55. The squall line is sweeping east into Alabama, Georgia and the Carolinas overnight as part of a multi-day severe weather outbreak across Dixie Alley.

Peak Driving Danger Window

The greatest risk runs from this evening through the overnight hours along I-55 between Jackson and McComb and along I-20 east into Meridian, where supercells are tracking at 35 to 50 mph and NWS Jackson has explicitly told drivers not to travel the interstate as cells pass.

What to Expect

• Tornado risk: Two confirmed large tornadoes already on the ground in Mississippi, with additional supercells capable of all hazards forecast overnight.
• Wind gusts: Damaging gusts to 70 mph within the warm sector, supported by 850-mb southwesterly flow at 35 to 40 knots.
• Hail and rain: Mixed-layer CAPE near 2,500 J/kg supports large hail; up to 4 inches of rainfall expected through Monday May 11.
• Worst corridors: I-55 (Jackson to McComb), I-20 (Jackson to Meridian), I-65 (Birmingham to Montgomery) and I-85 into Atlanta overnight.

The setup is driven by the same massive cold front that produced Colorado snow earlier this week. Mid-60s to lower-70s dewpoints south of the front and strong shear aloft are sustaining long-track supercells overnight, per the Storm Prediction Center.

Road Conditions

I-55 was directly in the path of the Brookhaven tornado, and Mississippi Governor Tate Reeves activated state Search and Rescue. With supercell tracks crossing I-20 and I-65 into Birmingham and Atlanta overnight, expect unannounced closures, debris on the roadway, and cells reaching Upstate South Carolina by sunrise. Hail to 2 inches or larger is plausible within the strongest cells, and any vehicle parked in the open is exposed to serious damage. Our breakdown of whether car insurance covers storm damage covers comprehensive versus liability before claims pile up. The Mississippi DOT traffic map tracks active closures.

Flash Flood Risk Across the Lower Mississippi Valley

Heavy to excessive rainfall is producing flash flooding from the Lower Mississippi Valley into the southern Appalachians, per the WPC. Multiple flood watches are active across Mississippi, Alabama, Tennessee and northern Georgia, with up to 4 inches of rain through Monday May 11 as storm rounds train over the same ground. Drivers on I-10, I-20 and I-65 should expect ponding, hydroplaning, and barricaded low-water crossings. Flooded vehicles often resurface on used-car lots months later, our guide to spotting flood-damaged vehicles is worth bookmarking before any post-storm shopping.

Severe Storm Driving Tips

If you are caught on the road with a tornado approaching, do not try to outrun it. Tornadoes change direction faster than highway speeds and debris fields extend well beyond the visible funnel. Pull off, exit the vehicle, and shelter in a sturdy structure or low ditch. Underpasses are not shelter, they create wind tunnels that accelerate debris. Even storm chasers with armored vehicles get overrun, our piece on how stormchasers drive inside a tornado is a useful reality check.

For flash flooding, the NWS Turn Around Don't Drown rule applies: 6 inches of moving water can knock down an adult, 12 inches can carry away a small car, and 18 to 24 inches sweeps away most SUVs and trucks. Check tire tread (4/32 minimum for heavy rain), top off washer fluid, and disengage cruise control once rain starts.

Timing

Tornado risk peaks tonight across central and eastern Mississippi, shifting into Alabama and Georgia overnight. Friday May 8 carries continued severe potential along the central Gulf Coast and into the Carolinas. Saturday May 9 a new SPC-flagged severe weather setup targets Texas, Oklahoma and Kansas as the next shortwave trough fires Plains storms. We'll update this article as conditions evolve.
