..SAFETY RULES FOR SEVERE THUNDERSTORMS
 
 
A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED BY THE NATIONAL  
WEATHER SERVICE. IN THE INTEREST OF PUBLIC SAFETY, THE  
FOLLOWING SAFETY RULES ARE PROVIDED. PUBLIC AND COMMERCIAL  
BROADCAST STATIONS SERVING THE AFFECTED AREA ARE ASKED TO  
BROADCAST THESE SAFETY MEASURES FREQUENTLY WHILE THE WATCH IS  
IN EFFECT.  
 
A SEVERE THUNDERSTORM WATCH MEANS CONDITIONS ARE FAVORABLE FOR  
THE DEVELOPMENT OF SEVERE THUNDERSTORMS IN AND CLOSE TO THE  
WATCH AREA. IF YOU ARE IN THE WATCH AREA, KEEP UP TO DATE OF  
THE LATEST WEATHER INFORMATION. THESE STORMS CAN DEVELOP  
RAPIDLY SO THERE MAY BE OCCASIONS WHEN ADVANCE WARNING IS NOT  
POSSIBLE.  
 
A SEVERE THUNDERSTORM WARNING MEANS A SEVERE THUNDERSTORM HAS  
BEEN OBSERVED OR INDICATED ON RADAR. IF YOU ARE IN THE PATH  
OR NEAR THE STORM, TAKE IMMEDIATE ACTIONS TO PROTECT LIFE AND  
PROPERTY. FOLLOW THESE SAFETY RULES:  
 
(1) IN OPEN COUNTRY, YOU SHOULD SEEK SHELTER AND AVOID TREES  
WHICH CAN BE TARGETS FOR LIGHTNING. IF THERE IS NO SHELTER,  
GO TO A DITCH OR CULVERT BUT BEWARE OF RISING WATER WHICH CAN  
CAUSE FLOODING.  
 
(2) WHEN INDOORS, STAY AWAY FROM OUTSIDE WALLS AND WINDOWS  
AND GO TO AN INTERIOR ROOM ON THE LOWEST LEVEL. AVOID USING  
ELECTRICAL APPLIANCES WHILE THE STORM IS NEARBY.  
 
(3) IN MOBILE HOMES, YOU SHOULD LEAVE AND SEEK NEARBY SAFE  
SHELTER.  
 
(4) IF SWIMMING OR ON A BOAT, YOU SHOULD GET TO SHORE AS  
QUICKLY AS POSSIBLE AND FIND SHELTER.  
 
A THUNDERSTORM IS CONSIDERED SEVERE WHEN IT CONTAINS ONE INCH  
OR LARGER DIAMETER SIZE HAIL AND/OR WIND GUSTS OF 58 MILES AN  
HOUR OR GREATER. A SEVERE THUNDERSTORM CAN ALSO PRODUCE DEADLY  
LIGHTNING AND VERY HEAVY RAIN WHICH CAN LEAD TO FLASH FLOODING.  
 
REMEMBER, WITH ANY SEVERE THUNDERSTORM THERE IS ALWAYS THE  
POSSIBILITY OF TORNADOES.
