Severe Weather Awareness:

Today's Topic: Lightning 

What is Lightning? 
 
The action of rising and descending air within a thunderstorm  separates  positive  and negative electrical charges.  Lightning results from the buildup  and  discharge  of  electrical  energy  between  these  positively  and  negatively  charged areas.    Lightning  charges may  reach  as  high  as 100 million volts.  This electrical charge is always searching for the path of least resistance to  complete the circuit.   
 
Lightning will  normally  strike  the  tallest  object  in the  area  of  the  potential  discharge.    Tall  trees, light poles and telephone lines are frequent  targets for lightning strikes. Lightning is always a potential  killer. Whether the storm is a large spring time severe storm or the  more common afternoon variety, it contains this deadly killer. It may strike an isolated tree or an object out in the open, or it may strike you.   
 
Keep in mind that you do not have to be standing directly beneath a cloud to be hit.   Lightning may strike many miles from the parent storm.  In an average year lightning  will  claim  more  victims than tornadoes or hurricanes.  

EVERY THUNDERSTORM CONTAINS LIGHTNING.   

Lightning Safety Rules—Outdoors 
 
Seek shelter inside a house, large building or an all metal vehicle with the windows rolled up (avoid convertibles). 
 
If your hair stands on end and your skin tingles... lightning is about to strike.  Take cover 
immediately! 
 
If you can't find appropriate shelter, get down to avoid being the highest point for a lightning discharge.  When caught in the open, seek shelter in a low area.  Crouch down and cover your head with your hands.  If you are with a group of people, everyone should scatter out before crouching. 
 
If  caught  in  a wooded  area seek out the area with the smallest trees.  Stand at least five feet 
from the trunk of the nearest tree to avoid flying bark, should the tree be hit by lightning. 
 
When boating, head for shore and get into a shelter, or vehicle.  If caught in a boat, lie  
down in the boat with cushions between you and the boat's side and bottom. 
 
AVOID 
Large trees, hilltops and other high places. 
 
Chain link fences and any other metal fences like those around ball parks and play grounds. 
 
Motorcycles, scooters, golf carts, small metal sheds, bicycles, tractors and farm equipment that does not have an enclosed metal cab. 
   
Do you know what group of people are most likely to get struck by lightning? It is farmers,  
followed then by golfers.
