Georgia Department of Transportation crews are treating north Georgia roads and bridges in anticipation of accumulating snow and ice Saturday night.

By early Friday evening, the DOT was warning drivers of passable but dangerous conditions along I-75 in Whitfield County.

The DOT advises people to travel in north Georgia only if necessary.

All of Georgia will be getting precipitation over the next 24 hour, with snow, ice and freezing rain in north Georgia and rain and thunderstorms in southern parts of the state.

Because of the forecast, several extreme north Georgia counties closed schools early Friday -- Fanin, Gilmer, Rabun, Towns, and Union county schools.

The National Weather Service has a winter storm warning in place through early Saturday afternoon for northeast Georgia. In addition, a wide area of southeast Georgia is under a flood advisory.

Friday's night's forecast calls for a mix of rain, snow, and sleet will take hold in north Georgia. Southern portions of the state will get showers and thunderstorms. Lows to range from the 30's to 50's.

Ahead on Saturday, rain showers likely with freezing rain and sleet changing to light snow northeast. Highs from the 30's to 60's.
