  • Disconnect or turn off appliances you were using when the power went off. Leave one light on to tell you when service is restored.
  • Avoid opening refrigerators or freezers. Food will stay frozen in a fully loaded freezer for 36 to 48 hours if the door is closed. In a half-full freezer, food will keep 24 hours.
  • Non-electric, unvented space heaters can be a hazard. Use them only in well-ventilated areas.
  • If you use an electric generator, plug appliances directly into it. Never plug a generator directly into your home's electrical wiring.

A winter storm warning officially began at 4 p.m. as a wintry mix started to fall over metro Atlanta. The advisory ends at 1 p.m. Saturday.

Some parts of Cobb, Cherokee, north Fulton and Forsyth counties could get more than 5 inches of snow Saturday, Channel 2 Action News meteorologists say.

That snow is expected to start accumulating about 11 p.m.

Temperatures started falling shortly after noon as the cold air moved in. Sleet was reported in Cobb, north Fulton, Cherokee, Paulding, Bartow and Floyd counties about 1:30 p.m. as road temperatures dropped on I-75 at Ga. 92 near Acworth from 43 degrees to 38 degrees.

Temperatures shortly after 8 p.m. were 32 degrees in Atlanta, 29 in Calhoun and 39 in Eatonton.

The Georgia Emergency Management Agency warned residents Thursday to prepare to stay at home for at least three days.

“With winter weather on the way,” the agency said, “now is the time to prepare.”

The Georgia Department of Transportation started mobilizing its fleet of brine trucks Thursday night in metro Atlanta. Brine is a salt and water solution used to prevent ice from forming. GDOT crews, some sent to metro Atlanta from counties in South Georgia, continued prep work Friday.

Meteorologist Brad Nitz tracks the winter storms's timing.

The Georgia Electric Membership Cooperatives, which represents the state’s 41 EMCs, mobilized employees and contract crews and prepared trucks with extra utility poles, wire, connectors, transformers and other emergency and power equipment, spokeswoman Terri Statham said Friday.

“Electric co-ops ... have a variety of contingency plans in place to address problems associated with ice and snow forming on power lines, possibly causing damage and service disruptions,” Statham said.

Many organizations decided to close through the weekend.

By about 7 a.m. Saturday, the snow will have moved out of the metro area, according to Channel 2. However, cold air is expected to move in behind the snow, meteorologist Karen Minton said.

“Sunday is just bitter cold,” she said.

Temps will drop into the teens.
