The Georgia Emergency Management Agency issued advice on the best and worst places to shelter from a tornado late on Saturday, advising locals in the path of a tornado to cover themselves with blankets or a mattress for protection.
It said the safest place to be is “a basement or interior room, stairwell, or hallway on a low floor”.
Windows, doors, and outside walls are to be avoided.
It also warned against underestimating flash floods, saying just six inches of fast-moving water can knock a person off his or her feet, and two feet can sweep away a full-sized car.
