At 106 AM EST...a strong thunderstorm was over Florence Marina State
Park, or 12 miles west of Lumpkin...moving northeast at 55 mph.

  HAZARD...Frequent cloud to ground lightning and heavy rain. 

  IMPACT...People outdoors should seek shelter immediately. 
           Lightning is one of nature's leading killers.

           not be used unless in an emergency. Motorists should slow 
           down and be prepared for possible loss of control due to 
           hydroplaning. Also...the heavy rain may cause temporary 
           street flooding or road ponding in slow drainage areas. 
           When water covers the road...remember to Turn Around 
           Don't Drown.
