PUBLIC INFORMATION STATEMENT  
NATIONAL WEATHER SERVICE BINGHAMTON NY  
800 AM EDT MON APR 23 2018  
 
THIS IS THE FIRST STATEMENT OUT OF FIVE INFORMATION STATEMENTS  
WHICH WILL RUN EACH DAY THIS WEEK FOR PENNSYLVANIAS'S SEVERE  
WEATHER AWARENESS WEEK.  
 
TODAY WE DISCUSS THE DIFFERENCE BETWEEN A TORNADO WATCH, A  
TORNADO WARNING, AND PROVIDE TIPS ON WHAT TO DO WHEN A WATCH OR  
WARNING IS ISSUED.  
   
..WHAT IS A TORNADO?
 
 
A TORNADO IS A VIOLENTLY ROTATING COLUMN OF AIR FROM THE BASE OF  
A THUNDERSTORMS THAT IS IN CONTACT WITH THE GROUND. WIND SPEEDS  
INSIDE A TORNADO RANGE FROM UNDER 100 MILES AN HOUR AND CAN EXCEED  
200 MILES AN HOUR. TORNADOES COME IN ALL SHAPES AND SIZES AND  
CAN TRAVEL AS FAST AS 70 MPH, AND CAN DESTROY VIRTUALLY EVERYTHING  
IN THEIR PATH.  
 
WHILE THE VAST MAJORITY OF TORNADOES THAT OCCUR IN THE STATE OF  
PENNSYLVANIA ARE NOT AS STRONG AS THEIR COUNTERPARTS IN THE MIDWEST,  
STRONG AND DAMAGING TORNADOES CAN AND DO OCCUR HERE AND IN THE  
NORTHEAST PORTION OF THE UNITED STATES. IN FACT, PENNSYLVANIA  
RANKS IN THE TOP 25 FOR TORNADO OCCURRENCE IN THE UNITED  
STATES, AVERAGING TWENTY TORNADOES PER YEAR. BETWEEN MAY  
31ST AND JUNE 2ND OF 1998, PENNSYLVANIA WAS HIT BY 40 TORNADOES,  
SOME OF WHICH HAD WIND SPEEDS OVER 150 MPH.  
   
..WHAT DOES A TORNADO WATCH MEAN?
 
 
A TORNADO WATCH IS ISSUED WHEN ATMOSPHERIC CONDITIONS ARE  
FAVORABLE, OVER A LARGE AREA, FOR TORNADOES AND SEVERE THUNDERSTORMS  
TO DEVELOP. A TORNADO WATCH IS ISSUED TO ALERT YOU AND YOUR FAMILY  
THAT IF A SEVERE THUNDERSTORM DEVELOPS, A TORNADO IS POSSIBLE. IT  
DOES NOT MEAN A TORNADO WILL OCCUR WITH EACH THUNDERSTORM, IT JUST  
MEANS IT IS POSSIBLE.  
   
..WHAT YOU SHOULD DO WHEN A TORNADO WATCH IS ISSUED?
 
 
GO ABOUT YOUR NORMAL ACTIVITIES, BUT WATCH THE SKY AROUND YOU  
FOR DEVELOPING STORMS. PERIODICALLY CHECK YOUR NOAA WEATHER RADIO,  
CELL PHONE FOR RADAR UPDATES, TV, RADIO, OR CELL PHONE APPS FOR  
UPDATES TO KEEP YOU WEATHER AWARE. ALWAYS KNOW WHICH COUNTY YOU  
LIVE IN, AND WHICH ONES BORDERS YOUR COMMUNITY. IF YOU ARE ON  
VACATION, OR DRIVING THROUGH AN UNFAMILIAR AREA, KEEP A MAP ON HAND  
AND KNOW YOUR LOCATION AT ALL TIMES IN CASE DANGER ARISES. NEWER  
CELL PHONES ARE EQUIPPED WITH WIRELESS EMERGENCY ALERTS (WEA). WEA  
ARE EMERGENCY MESSAGES SENT BY AUTHORIZED GOVERNMENT ALERTING  
AUTHORITIES THROUGH YOUR MOBILE CARRIER. GOVERNMENT PARTNERS  
INCLUDE: FEMA, FCC, DEPARTMENT OF HOMELAND SECURITY AND THE NWS.  
WEA WILL ALLOW YOU TO RECEIVE EXTREME WEATHER WARNINGS, LOCAL  
EVACUATIONS, AMBER ALERTS AND PRESIDENTIAL ALERTS DURING A NATIONAL  
EMERGENCY. ALWAYS HAVE A PLAN ON HOW TO GET TO A SAFE PLACE QUICKLY  
IF A WARNING IS ISSUED FOR YOUR AREA.  
   
..WHAT DOES A TORNADO WARNING MEAN?
 
 
A TORNADO WARNING IS ISSUED WHEN DOPPLER RADAR SHOWS A DEVELOPING  
TORNADO, OR A WHEN TORNADO HAS BEEN SIGHTED BY TRAINED WEATHER  
SPOTTERS, COUNTY EMERGENCY OFFICIALS, LAW OFFICIALS OR CREDIBLE  
CALLS FROM THE PUBLIC. A TORNADO WARNING MEANS A TORNADO IS  
GOING TO MOVE THROUGH YOUR AREA SOON, SO YOU NEED TO TAKE  
IMMEDIATE ACTION TO PROTECT YOUR LIFE. TORNADO WARNINGS TYPICALLY  
RANGE IN DURATION FROM 30 TO 60 MINUTES.  
   
..WHAT YOU SHOULD DO WHEN A TORNADO WARNING IS ISSUED?
 
 
TAKE IMMEDIATE ACTION AND REMAIN CALM. IF YOU ARE AT HOME OR  
IN A STURDY BUILDING, GO TO THE BASEMENT OR TO AN INTERIOR ROOM  
ON THE LOWEST FLOOR. CLOSETS, BATHROOMS, AND OTHER INTERIOR ROOMS  
OFFER THE BEST PROTECTION. GET UNDER SOMETHING STURDY OR  
COVER YOURSELF WITH A MATTRESS.  
 
IF YOU ARE IN A SCHOOL, HOSPITAL, OR SHOPPING CENTER GO TO A  
PRE-DESIGNATED SHELTER AREA. STAY AWAY FROM LARGE OPEN AREAS AND  
WINDOWS. DO NOT GO OUTSIDE TO YOUR CAR. YOUR CAR IS A VERY  
DANGEROUS SHELTER IN PLACE TO GO TO IN THE EVENT OF A TORNADO.  
IF YOU ARE IN A HIGH-RISE BUILDING, GO TO AN INTERIOR SMALL ROOM  
OR HALLWAY ON THE LOWEST FLOOR POSSIBLE. DO NOT USE THE ELEVATOR,  
USE THE STAIRS INSTEAD.  
 
FOR THE BEST PROTECTION POSSIBLE, GET UNDER SOMETHING STURDY OR  
DROP TO YOUR KNEES FACING AN INTERIOR WALL. LEAN FORWARD WITH YOUR  
HANDS SHIELDING YOUR HEAD.  
 
GET OUT OF MOBILE HOMES OR VEHICLES. THEY ARE EASILY TOSSED ABOUT  
BY STRONG WINDS IN THE TORNADO. TAKE SHELTER IN A SUBSTANTIAL  
STRUCTURE. IF THERE IS NO SHELTER NEARBY, LIE FLAT IN A DITCH OR LOW  
SPOT WITH YOUR HANDS SHIELDING YOUR HEAD. NEVER STAY INSIDE THE  
MOBILE HOME OR VEHICLE.
