Meteorologist Eli Jacks from the National Weather Service said in an interview with the Associated Press that "three -quarters of an inch of ice anywhere would be catastrophic. President Obama declared a state of emergency for Georgia on Tuesday and the state's officials promised to be more coordinated after a late January snowstorm paralyzed Atlanta.
Below is a graphic of the latest snowfall and ice total estimates for the state of Georgia from the National Weather Service. More than half an inch of ice is expected in Atlanta. For you.

That's what typically happens, said Marie-Eve Giguere, a warning preparedness meteorologist based at the Environment Canada's Downsview office in Toronto.
In this case, though, two back-to-back weather systems brought large amounts of precipitation into the region between Friday and Sunday morning, while the slow movement of the combined storm allowed for ice accumulations of as much as three centimetres in some of the worst hit locations from Niagara to Kingston.
The sheer weight of accumulating ice is often enough to bring down vulnerable trees and power lines. Ice can also short out transformers, wreaking further havoc on the power grid. The storm unfolded along a line from northern Texas to Nova Scotia.
The line roughly defines the boundary between a mass of cold air that has lately been stationed over the Prairies and a region of much warmer air that has brought unseasonably mild temperatures to the mid-Atlantic states.
New York's Sunday high topped 20 C. But how does a winter storm form? Winter storms begin with moist air rising up into the atmosphere, just like other types of storms. Rising air is common at a cold front, where warm air is lifted above cold air and is necessary for cloud formation and precipitation.
Rising air can also happen as air moves up a large hill or mountain. A source of moisture, such as air blowing across a large lake or ocean, is necessary for clouds and precipitation to form.
The final ingredient, and the one that makes a winter storm different from other storms, is cold air. Below freezing air temperatures near the ground and up to the clouds will cause precipitation to fall as either snow or ice.
However, extremely cold air is not able to hold as much moisture and thus will not make much snow. This explains why some of the coldest places on Earth, like Antarctica, receive very little precipitation throughout the year.
Snowstorms are one type of winter storm. Blizzards are snowstorms with high winds, and lake effect storms are snowstorms that form near the Great Lakes.
Ice storms can bring freezing rain or sleet as well as snow. Read below to learn more about the different kinds of winter storms. A storm where precipitation falls as snow is called a snowstorm.
