..PUBLIC INFORMATION STATEMENT
 
 
   
..TORNADO WATCH SAFETY RULES
 
 
A TORNADO WATCH MEANS THAT CONDITIONS ARE FAVORABLE FOR THE  
DEVELOPMENT OF TORNADOES IN THE DESIGNATED AREA. DURING A WATCH  
THERE IS NO CAUSE FOR IMMEDIATE CONCERN. YOU SHOULD GO ABOUT YOUR  
NORMAL BUSINESS...BUT BE ON THE LOOKOUT AND KEEP UP TO DATE ON THE  
LATEST WEATHER DEVELOPMENTS. PUBLIC SAFETY OFFICIALS SHOULD  
ACTIVATE PREARRANGED PLANS.  
 
A TORNADO WARNING MEANS THAT A TORNADO HAS BEEN SIGHTED OR  
INDICATED BY RADAR. MOVE QUICKLY TO SAVE YOURSELF AND YOUR FAMILY.  
IF YOU HAVE A REHEARSED PLAN OF ACTION...YOU SHOULD FOLLOW IT. THE  
NATIONAL WEATHER SERVICE ADVISES THE FOLLOWING SAFETY RULES:  
 
IN A HOME...ONE OF THE BEST SHELTERS IS IN THE BASEMENT...UNDER  
HEAVY FURNITURE AND WHERE OVERHEAD SUPPORT AND PROTECTION ARE THE  
GREATEST. IF THERE IS NO BASEMENT...GO TO THE CENTER OF THE HOUSE  
ON THE LOWEST FLOOR. GET INTO A SMALL ROOM...SUCH AS A CLOSET OR  
BATHROOM...OR AN INTERIOR HALLWAY UNDER HEAVY FURNITURE. SOME HAVE  
FOUND THAT AN EMPTY BATHTUB WITH A MATTRESS OR BLANKET FOR COVER  
MAKES A GOOD EMERGENCY REFUGE.  
 
IN A SCHOOL...OFFICE BUILDING OR OTHER TYPE OF INSTITUTIONAL  
BUILDING...FOLLOW YOUR REHEARSED PLAN OF ACTION. GO QUICKLY TO A  
BASEMENT IF AVAILABLE. IF NONE IS AVAILABLE...GO TO A CENTRAL HALL  
OR CORRIDOR ON THE LOWEST FLOOR. KEEP AWAY FROM OUTSIDE  
WALLS...DOORS AND WINDOWS. STAY OUT OF AUDITORIUMS AND GYMNASIUMS.  
 
IF IN OPEN COUNTRY OR IN A CAR...AND YOU CAN NOT AVOID THE PATH OF  
THE STORM...GET INTO A DITCH...DEPRESSION OR CULVERT. LIE FLAT AND  
MAKE AS SMALL A TARGET AS POSSIBLE. IF YOU CAN...WRAP A COVERING  
AROUND YOURSELF. EVEN SMALL GROUND DEBRIS CAN CAUSE SERIOUS INJURY  
WHEN DRIVEN BY TORNADO STRENGTH WINDS.  
 
IN A MOBILE HOME...WHETHER IT IS TIED DOWN OR NOT...ABANDON IT AND  
GO TO A COMMUNITY SHELTER...NEIGHBORS HOUSE...OR GET INTO A DITCH.  
 
YOUR NATIONAL WEATHER SERVICE ADVISES YOU TO MEMORIZE THESE BASIC  
SAFETY RULES. YOUR LIFE MAY DEPEND ON YOU KNOWING THEM.
