A tornado watch is in effect for much of central and north Georgia until 4 p.m. Wednesday (Jan. 30), according to the National Weather Service.

The tornado watch area includes Snellville.

This is a watch, not a warning, which means be ready to act, but the threat is not imminent. A tornado watch means conditions are favorable of development of severe thunderstorms and tornadoes. If this becomes a warning, Patch will send out a breaking news alert.
