ATLANTA — A severe weather outbreak continues across the southeast Saturday evening and overnight.
Here in north Georgia, our threat of severe weather will ramp up this evening and continue overnight.
A tornado watch is in effect for parts of the Atlanta metro area, middle Georgia and southward until 10 a.m. Sunday. This includes counties as far east the Georgia-South Carolina line.
A tornado watch means conditions are favorable for the development of tornadoes. If you’re placed under a tornado warning, that means a tornado is likely, imminent, or already occurring and you should immediately seek shelter.
Portions of north Georgia are included in a level 4 out of 5 ‘moderate’ risk for severe weather, and the remainder of the 11Alive viewing area is in a level 3 out of 5 ‘enhanced’ risk.
We could see numerous severe thunderstorms with strong straight-line winds of 60 to 70+ mph, strong tornadoes, very heavy rain, and 1″ to 2″ hail.
We’ve issued a Weather Impact Alert due to the magnitude and large area that strong and severe thunderstorms could potentially impact over the weekend.
Straight-line winds will be our most widespread severe weather threat, with some wind gusts around 70 mph possible. The tornado threat will be greatest across western Georgia and should become slightly less favorable later overnight as we lose some of the instability in eastern Georgia.
Heavy rainfall will also be widespread. Rain totals could reach two to three inches in spots, creating a localized flash flooding possibility.
The greatest risk of severe weather will come during the evening and overnight, first arriving in northwest Georgia. Here is a rough window for when we anticipate the widespread storms to enter your part of Georgia. Storms can also happen outside that window. We go through a more detailed timeline below.
Storms spread into the Atlanta metro around midnight. This will be mainly a late evening and overnight event, so you must have a way to get alerts that will wake you if needed.
The line of storms will continue to push southeast through the night.
A few showers and storms may linger behind the main line, but by sunrise, the bulk of the activity will be over.
- Know your county of residence and how to find it on a map
- Know your ‘safe place’ to go if you are placed in a tornado warning polygon Saturday evening and overnight
- Communicate with your family and friends to make sure they’re aware of the incoming severe weather
