Barrow County is now under a Winter Storm Warning for snow and ice through 7 a.m. Thursday.
The National Weather Service is forecasting mostly freezing rain tonight and Wednesday, and then snow Wednesday night.
Accumulations of 2-4 inches of snow and up to one-half inch of ice are possible during the period. The more significant amounts of precipitation will fall Wednesday.
Barrow County schools are closed today, and all school-related activities and meetings are canceled. The Barrow County government will be closed Wednesday.
The Georgia Department of Transportation has urged the public to "refrain from all but absolutely necessary driving" throughout the three days of the storm.
Driving conditions will worsen throughout the day today and particularly tonight and into Wednesday, carrying the risk of significant icing, the press release states.
Georgia Gov. Nathan Deal on Monday declared a "state of emergency" in 45 counties, including Barrow, because of the approaching winter storm.
Local emergency officials participated in a National Weather Service briefing Monday morning.
"It's two events, not one four-day event," said Barrow County Sheriff Jud Smith, who participated in the briefing.
At 5 a.m. today, Barrow County Emergency Services partially staffed its Emergency Operation Center, according to a press release issued Monday afternoon. It will operate until Thursday or longer if necessary.
"We also have contingency plans that are based on the amount of precipitation and call volume," said Lt. Scott Dakin, BCES public information officer.
