ATLANTA (AP) — Utility companies say more than 67,000 Georgia customers remain without power as crews work to clear downed trees and power lines.

Georgia's electric membership cooperatives reported that about 53,000 customers throughout the state were without power as of 10 a.m. Wednesday after an ice storm coated much of northeast Georgia. A Georgia Power outage map also showed that more than 14,000 of its customers were without power late Wednesday morning.

The electric cooperatives said in a statement that restoring power has been challenging since many areas have been impassable and trees and debris need to be removed.

The winter storm also caused some flight delays at the Hartsfield-Jackson Atlanta International Airport.
