Timeline for New Year's weekend storms in Atlanta, north Georgia

A few strong to severe thunderstorms will be possible.

ATLANTA — The calendar may no longer say 2021, but our weather forecast to start the new year looks eerily similar to how the year ended. The 11Alive StormTrackers are tracking another round of strong and severe thunderstorms for the Atlanta metro and North Georgia.

Here are three things to know:

- Severe storms are most likely from Saturday evening through Sunday morning

- Damaging winds, heavy rain, lightning, and an isolated spin up tornado will be possible

- Have a way to get warnings while you're asleep. Enable wireless emergency alerts on your phone or use a NOAA Weather Radio. You can also download the 11 Alive App

Severe Storm Threats:

We have a Level 3 threat of severe weather in far Northwest Georgia, a Level 2 threat for the Atlanta area, and a Level 1 threat for areas southeast of the metro.

Damaging winds will be our primary severe weather threat. An isolated tornado is possible. Hail is a very low threat as well and heavy rain is likely. Falling on saturated ground, additional heavy rain could lead to flooding.
