ATLANTA (AP) — Utility companies say more than 20,000 Georgia customers remain without power after this week's ice storm as low temperatures dipped into the single-digits in northern parts of the state.

Georgia's electric membership cooperatives reported that about 22,000 customers were without power as of 5 a.m. Thursday after an ice storm coated much of northeast Georgia.

Meanwhile, the temperature plunged to 6 degrees in Blairsville before dawn Thursday as a new storm approached. A U.S. Forest Service weather station near Brasstown Bald, Georgia's highest peak, showed the air temperature there was 1 degree early Thursday.

The National Weather Service early Thursday warned of a new storm that could bring up to a quarter of an inch of ice to far north Georgia Friday night through Saturday morning.
