Motorists should use extra caution due to a dense fog advisory in effect until 10 a.m. Tuesday for central and southern parts Georgia.

The National Weather Service expects dense fog to limit visibility to a quarter mile or less for communities south of a line from Columbus to Macon to Warrenton.

Drivers should use their low-beam headlights for greater visibility even after the sun rises.

Ample moisture is flowing up from the Gulf of Mexico ahead of a frontal system that could bring thunderstorms to Middle Georgia after 10 a.m. Wednesday.

Winds will pick up Tuesday night with gusts of 25 miles per hour expected to increase to 40 miles per hour Wednesday.
