ATLANTA (AP) — Authorities are urging Georgia drivers to be cautious on streets and highways, as melting snow and ice forms treacherous conditions in some spots.

The National Weather Service said early Friday that areas of black ice would continue Friday morning as temperatures had dropped below freezing as far south as LaGrange and Macon and points to the north.

Forecasters said they expected temperatures to rise above freezing later Friday morning and warm into the 50s across much of the state.

High temperatures in the mid-50s were expected in metro Atlanta on Friday.

In Augusta, an area hard-hit by this week's ice storm, the National Weather Service was projecting a high of 56 on Friday.
