Atlanta Georgia New Orleans Louisiana and Mobile Alabama Face Level 1 Tornado Risk Thursday as Tropical System Remnants Slide Across the Gulf Coast

ATLANTA, GEORGIA — The most likely place in the United States to see a tornado Thursday June 18 has shifted to the Southeast, with Atlanta, New Orleans, and Mobile sitting inside a Level 1 tornado likelihood zone as the remnants of a tropical system sliding across the Gulf Coast could spin up a quick tornado or two across the region.

Level 1 Tornado Zone Covers Gulf Coast Through Atlanta Thursday

The Day 2 SPC tornado likelihood outlook updated June 17 at 3:33 AM ET valid Thursday June 18 shows a Level 1 Possible tornado zone in pink covering a broad corridor from New Orleans and Lafayette northeastward through Hattiesburg, Mobile, and extending into Atlanta and Savannah. The zone also pushes toward Jacksonville and Tallahassee along the Florida border.

This corridor represents the highest tornado probability anywhere in the country for Thursday, with the focus shifting entirely away from the Midwest and down to the Gulf Coast and Southeast as tropical system remnants interact with the region.

Tropical Remnants Could Spin Up Quick Tornadoes Across the Gulf Coast

The tornado threat Thursday is driven specifically by the remnants of the tropical system that has been tracking along the Gulf Coast, with forecasters noting those leftovers could produce a quick tornado or two as they slide through the New Orleans, Mobile, and Atlanta corridor. Tropical remnant tornadoes tend to be brief and fast-moving, making timely warning response essential.

The Level 1 designation reflects relatively low overall probability but still represents the single highest tornado likelihood zone nationally for Thursday.

Southeast Residents Should Monitor Thursday Forecast Closely

Communities across New Orleans, Mobile, Hattiesburg, Jackson, and Atlanta should monitor Thursday’s forecast closely as the tropical system remnants track through the region. Quick spin-up tornadoes associated with tropical features can develop rapidly with minimal lead time, making active weather alert notifications essential for anyone in the highlighted zone Thursday.
