..CONDITIONS ARE FAVORABLE FOR FUNNEL CLOUDS
 
 
A FUNNEL CLOUD WAS REPORTED JUST WEST OF LAURENS BETWEEN 345 AND 4  
PM. CURRENT ATMOSPHERIC CONDITIONS SUPPORT THE DEVELOPMENT OF  
FUNNEL CLOUDS. USUALLY, THESE FUNNEL CLOUDS CAN FORM FROM SHOWERS  
AND WEAK THUNDERSTORMS. THESE FUNNELS ARE NORMALLY BRIEF, DROP  
ONLY A FEW HUNDRED FEET FROM THE CLOUD BASE, AND RARELY BECOME A  
TORNADO OR CAUSE DAMAGE. HOWEVER, IF ONE IS SPOTTED, PLEASE  
IMMEDIATELY REPORT IT TO THE NATIONAL WEATHER SERVICE. IF A  
TORNADO WARNING WOULD BECOME NECESSARY, TAKE APPROPRIATE ACTION.
