The extent of the storm damage was unclear early Monday afternoon. Mayor Keisha Lance Bottoms tweeted photos of downed trees in her southwest Atlanta neighborhood, while Dru Ghegan, owner of the bonded warehouse in Fulton County, shared photos showing that the building had suffered significant damage.
The storm that triggered the warning was moving towards the eastern metropolitan area and weakened. A severe thunderstorm warning was in effect until 12:00 p.m. for parts of central DeKalb and southwestern Gwinnett counties, including Lawrenceville, Lilburn and Stone Mountain.
Overall, a tornado watch is in effect until 4 p.m. ET for parts of Georgia and Alabama, including Atlanta, Macon, and Montgomery, as additional thunderstorms could produce a few tornadoes in this. surveillance zone throughout the afternoon. Hail up to 1 inch and damaging winds up to 70 mph are possible with some of these storms.
Additionally, over the plains a new system is being developed that will trigger a separate severe weather outbreak overnight.
Tornadoes are very likely in the Southern Plains and in the Ohio River Valley
This area has the best chance of seeing damaging winds, but large hail and tornadoes are also possible, especially in southeastern Oklahoma and northeastern Texas.
“Very large hailstones, tornadoes (some of which can be significant) and strong and destructive winds are expected,” according to the Storm Prediction Center.
Monday morning showers and storms were expected to leave the Ohio River Valley by noon, while the southern plains remain dry for most of the day.
“A tornado risk may persist overnight as storms move from Oklahoma to parts of Arkansas / southern Missouri and approach the Mississippi River late,” according to the CPS.
Series of storms are possible overnight, so some places could be hit by more than one storm – perhaps more than one severe storm.
These storms may not reach the western Ohio River Valley until Tuesday morning, which could impact cities such as Nashville, Indianapolis, St. Louis and Louisville.
Severe storms also threaten in the southeast
Marginal, level 1 in 5, the chances of severe storms extend from the deep south to the mid-Atlantic. Cities like Washington, Richmond and Savannah are all included in this risk zone.
Unlike the central United States, the threat in the southeast will be primarily during the day.
There have already been thunderstorms this morning, and more storms will form during the second half of the day.
This round will have to be watched for severe storms this afternoon and evening. Reports of tornadoes, hail and damaging winds are expected with some of the storms. Localized flash floods will be possible with any storm today, with some locations measuring between 1 and 3 inches of rain.
Many southeastern states have seen their normal precipitation double over the past month, so even 1 to 2 inches of extra rain could lead to flash flooding.
Storms march east on Tuesday
This puts Mississippi at risk for tornadoes, but tornadoes could be especially possible in parts of Louisiana, Alabama, and Tennessee, where there is a level 3 in 5 severe weather risk.
“Large hail, damaging wind gusts and a few tornadoes will be likely with precipitation rates exceeding one inch per hour,” the National Weather Service office in Jackson, Mississippi said.
A few showers and storms could be possible during the day, particularly in the Tennessee River Valley, but the main event will take place Tuesday evening through Tuesday evening in the Gulf Coast states.
A squall line is expected to form resulting in widespread storms. This line should reach north to the Great Lakes, but storms are likely to be more dispersed.
Flash floods will be possible across the south thanks to the combination of heavy rains and all the rains that have fallen in recent days and weeks. Widespread rain of 1 to 3 inches is forecast in this area through Tuesday evening.
That storm line is expected to weaken by Wednesday morning as it approaches the U.S. east coast, but isolated severe weather conditions will still be possible.
