State transportation officials are asking motorists who must use metro Atlanta's road network Wednesday morning to wait until after daylight, when it will be easier to spot – and to avoid – black ice.
"Currently, the majority of interstates are passable; however refreezing is expected in some areas due to overnight temperature drops," said Jill Goldberg, deputy press secretary for the Georgia Department of Transportation.
"Motorists that must use the roads in the morning are urged to delay the start of their trip until after daylight so greater visibility is possible. Extreme caution is urged for those driving on the roadways."
Goldberg said work crews would work through the night to continue clearing state roadways.
The National Weather Service at 10:35 p.m. Tuesday issued a "special weather statement" for Barrow County and the region. It says the "new" area of Arctic air surging into Tuesday night would remain "firmly entrenched across the region through early Friday before a warming trend is expected to begin."
Weather service officials joined the refrain of GDOT and local public safety officials, urging caution on the roadways and telling motorists who do venture away from home to be prepared for hazardous driving conditions.
"With only minor melting during the afternoons from sunshine, the remaining slush will refreeze solid at night, and areas of water standing or running across roadways will likely freeze and leave areas of black ice."
Morning lows Wednesday and Thursday are expected to be in the teens, and highs both days may remain below freezing, states the weather service announcement.
"Use extreme caution if you must travel. Slow down and allow extra time to reach your destination."
