Ice Accumulation Measurements Show Northeast Georgia Hardest Hit as Metro Atlanta Sees Widespread Glazing

Ice totals vary sharply across the region

Measured ice accumulations from the weekend winter storm show a pronounced gradient across metro Atlanta and north Georgia, with the highest totals concentrated in the far northeast. Several locations reported ice amounts capable of creating hazardous travel conditions and elevating the risk of tree damage and power interruptions.

In the hardest-hit corridor, ice totals approached or exceeded half an inch in multiple communities. Near Lake Lanier, measured accumulation was close to 0.8 inches. Nearby, Clayton in Rabun County reported about 0.75 inches, while Toccoa measured roughly 0.60 inches. Cleveland and Vogel State Park each recorded about 0.50 inches.

Metro Atlanta recorded lighter, but still disruptive, accumulations

Across the northern metro, several communities measured around 0.40 inches, including Milton and Dahlonega. Elsewhere in metro Atlanta, totals were generally lower but widespread: multiple areas reported about a quarter inch, including Tucker, Dunwoody, Lawrenceville, Canton, Acworth and Snellville.

Even modest ice accretion can produce outsized impacts in the Atlanta region, where brief temperature changes can alter precipitation type and where elevated structures such as bridges and overpasses can freeze faster than surrounding roadways.

Road safety warnings and government response

State officials warned that lingering moisture and overnight refreezing can create black ice, particularly during morning hours when temperatures remain below freezing. The Georgia Department of Transportation reported it treated approximately 18,000 miles of roads ahead of the storm, using about 1.5 million gallons of brine and roughly 2,500 tons of a salt-and-aggregate mix. Officials also noted that a number of state routes experienced closures or restrictions as crews worked to clear debris and address dangerous conditions.

“Ice travel is no travel.”

Power outages and service disruptions

Storm impacts extended beyond roadways. By Sunday evening, statewide outage reports indicated tens of thousands of customers without electricity, with utility crews and state agencies focused on removing downed limbs and restoring service. The governor’s previously issued state of emergency remained in effect as agencies coordinated response efforts, including support from the National Guard.

Multiple school systems and institutions across metro Atlanta and north Georgia closed Monday, Jan. 26, as officials assessed road conditions and continued cleanup.

Key measured ice accumulations

• Lake Lanier area: ~0.8 inches
• Clayton (Rabun County): ~0.75 inches
• Toccoa: ~0.60 inches
• Cleveland and Vogel State Park: ~0.50 inches
• Milton and Dahlonega: ~0.40 inches
• Tucker, Dunwoody, Lawrenceville, Canton, Acworth, Snellville: ~0.25 inches

Officials said the key near-term concern is refreezing as temperatures fall again, potentially extending the period of hazardous travel beyond the end of precipitation.
