Dawson County School Superintendent Keith Porter just announced schools will be closed for students on Tuesday in anticipation of subzero weather moving in later today.
Staff should report at 9 a.m. or when travel is safe, he said.
All sports and extra-curricular activities scheduled for Tuesday are also cancelled.
A wind chill advisory is in effect until 1 p.m. Tuesday. Rain changing to snow, with some brief sleet is possible.
The winter weather advisory warns that frostbite and hypothermia are possible if proper precautions are not taken. Temperatures are forecasted to fall into single digits overnight Tuesday with a wind chill of as low as 13 below zero.
Temperatures aren't expected to climb above freezing until Wednesday.
"Temperatures are definitely going to be the worst part," Alex Gibbs, an NWS meteorologist from the Peachtree City office, said Saturday. "That's the biggest concern as far as safety."
