Charleston, SC – A Cold Weather Advisory is in effect for Charleston and much of the South Carolina Lowcountry and southeast Georgia, as a surge of Arctic air is expected to drive temperatures down to near 17 degrees overnight Monday into early Tuesday.
According to the National Weather Service in Charleston, the advisory runs from 8 p.m. Monday through 9 a.m. Tuesday, covering inland portions of Berkeley, Dorchester, Jasper, Colleton, Allendale, and Hampton counties in South Carolina, along with multiple counties across southeast Georgia.
Forecasters say this will likely be the coldest night of the season so far, with sustained sub-freezing temperatures lasting several hours before sunrise. Wind chills could make conditions feel even colder during the overnight and early morning hours, increasing the risk of cold-related illness.
Officials warn that frostbite and hypothermia are possible if skin is exposed to the cold for extended periods. Vulnerable populations, including the elderly, young children, and those without reliable heating, face the highest risk.
The cold snap may also impact pets, livestock, and sensitive outdoor equipment. Residents are encouraged to bring pets indoors, check on neighbors, and ensure adequate heating is available. Those heading out early Tuesday should dress in layers and limit time outdoors.
Motorists traveling overnight or during the Tuesday morning commute may encounter icy patches on bridges and elevated roadways, especially in rural areas where temperatures drop fastest.
Temperatures are expected to gradually rebound Tuesday afternoon as sunshine returns, though forecasters say additional cold mornings remain possible later this week.
Residents are urged to continue monitoring updates from the National Weather Service and local emergency management officials as the cold advisory period approaches.
