The National Weather Service has issued two weather alerts in an area that includes Barrow County, and the approaching winter storm could pack a wallop over the next four days.
A “Winter Weather Advisory” is in effect from 7 p.m. tonight until 7 p.m. Tuesday in North Georgia mainly along and north of a line from Carrollton to Atlanta to Washington. During this 24-hour period, up to one inch of snow is expected to accumulate.
That will be followed by a second round of precipitation from Tuesday night through Thursday morning — during which there could be another 1-2 inches of snow and .10-.25 of an inch of ice.
This second weather alert — currently a “Winder Storm Watch” — is in effect from Tuesday evening through Thursday morning. The forecasted timing of the precipitation is as follows:
•Monday night: Rain will possibly change over to snow or a snow-sleet mix by sunrise Tuesday morning.
•Tuesday: As temperatures warm during the day, precipitation will likely change to rain.
•Tuesday evening: The precipitation likely will transition back to a mix of rain, sleet and snow.
•Wednesday morning: Expect a mix of sleet and freezing rain.
•Thursday morning: The precipitation should transition back to snow.
If there is icing as expected, it could create “impossible driving conditions” and bring down large tree limbs and cause power outages.
However, the weather alert notes that there is still some uncertainty.
“There is still some uncertainty in the forecast for Wednesday, but confidence is increasing in the potential for a significant winter storm. Folks across North Georgia should monitor this situation closely in the event that the advisory or watch are upgraded to a warning."
