PUBLIC INFORMATION STATEMENT

..PENNSYLVANIA SEVERE WEATHER AWARENESS WEEK
 
 
THIS WEEK, APRIL 23RD THROUGH APRIL 27TH, IS SEVERE WEATHER  
AWARENESS WEEK IN PENNSYLVANIA.  
 
NOW IS THE TIME TO PREPARE FOR THE UPCOMING SEVERE WEATHER SEASON.  
 
WE ARE COVERING A DIFFERENT SAFETY TOPIC EACH DAY OF THIS WEEK.  
 
OUR SEVERE WEATHER AND WEATHER SAFETY TOPIC FOR TODAY IS,  
SEVERE THUNDERSTORMS.  
 
WE WILL COVER WHAT CLASSIFIES A THUNDERSTORM AS SEVERE, AND WHAT  
THE DIFFERENCES ARE BETWEEN A SEVERE THUNDERSTORM WATCH AND A SEVERE  
THUNDERSTORM WARNING. WE WILL ALSO GIVE YOU INFORMATION ON WHAT TO  
DO WHEN A WATCH OR WARNING IS ISSUED FOR YOUR AREA.  
 
WHAT IS A SEVERE THUNDERSTORM?  
 
A THUNDERSTORM IS CONSIDERED SEVERE IF IT PRODUCES WIND GUSTS  
OF 58 MILES AN HOUR OR HIGHER, AND/OR HAIL ONE INCH IN  
DIAMETER OR LARGER. THOSE HAILSTONES ARE ABOUT THE SIZE OF A  
QUARTER. SEVERE THUNDERSTORMS ARE OFTEN ACCOMPANIED BY  
TORRENTIAL DOWNPOURS AND FREQUENT LIGHTNING. THEY CAN ALSO  
PRODUCE BRIEF, WEAK TORNADOES. THE DAMAGE FROM THE STRONG WIND  
GUSTS OF A SEVERE THUNDERSTORM CAN BE JUST AS BAD AS THE DAMAGE  
MADE BY A TORNADO. SEVERE THUNDERSTORMS ARE MUCH MORE COMMON THAN  
TORNADOES.  
 
WHAT IS A SEVERE THUNDERSTORM WATCH?  
 
A SEVERE THUNDERSTORM WATCH IS ISSUED IN ORDER TO ALERT YOU THAT  
THUNDERSTORMS WITH DAMAGING WINDS AND LARGE HAIL ARE EXPECTED TO  
DEVELOP CLOSE TO YOUR LOCATION. A WATCH BY ITSELF DOES NOT MEAN  
THAT SEVERE WEATHER IS ACTUALLY OCCURRING YET, IT MEANS THAT  
SEVERE WEATHER IS EXPECTED TO HAPPEN CLOSE BY. A SEVERE  
THUNDERSTORM WATCH USUALLY COVERS AN AREA AS LARGE AS A STATE,  
AND IS IN EFFECT FOR SEVERAL HOURS, EXPIRING ONLY WHEN THE  
THUNDERSTORMS ARE EXPECTED TO END.  
 
WHAT SHOULD YOU DO WHEN A SEVERE THUNDERSTORM WATCH IS ISSUED?  
 
GO ABOUT YOUR NORMAL ACTIVITIES, BUT WATCH THE SKY AROUND YOU  
FOR DEVELOPING STORMS. PERIODICALLY CHECK NOAA WEATHER RADIO OR  
OTHER MEDIA OUTLETS FOR FORECAST UPDATES AND POSSIBLE WARNINGS.  
KNOW WHICH COUNTY YOU LIVE IN, AND WHICH ONES BORDER YOUR  
COMMUNITY. THINK OF A SAFE PLACE TO BE AND PLAN A ROUTE WHICH  
YOU CAN USE TO GET THAT SAFE PLACE QUICKLY.  
 
WHAT IS A SEVERE THUNDERSTORM WARNING?  
 
A SEVERE THUNDERSTORM WARNING MEANS A SEVERE THUNDERSTORM IS  
OCCURRING AND IS GOING TO MOVE THROUGH YOUR LOCATION SOON. IT IS  
YOUR SIGNAL THAT YOU WILL NEED TO TAKE QUICK ACTION TO PROTECT YOUR  
LIFE AND PROPERTY. SEVERE THUNDERSTORM WARNINGS ARE ISSUED BY THE  
NATIONAL WEATHER SERVICE WHEN METEOROLOGISTS DETECT A SEVERE  
THUNDERSTORM USING DOPPLER RADAR OR WHEN DAMAGE HAS BEEN REPORTED BY  
TRAINED SKYWARN WEATHER SPOTTERS.  
 
TYPICALLY, A SEVERE THUNDERSTORM WARNING WILL BE ISSUED FOR AN AREA  
AS BIG AS A COUNTY OR TWO, AND FOR A PERIOD OF UP TO ONE HOUR. IN  
THE TEXT OF THE WARNING STATEMENT, WE TRY TO MAKE A SPECIFIC LIST  
OF TOWNS THAT ARE LIKELY TO BE IN THE PATH OF THE STORM. YOU SHOULD  
LISTEN TO HEAR IF COMMUNITIES OR LANDMARKS NEAR YOU ARE MENTIONED IN  
THE WARNING.  
 
WHAT SHOULD YOU DO WHEN A SEVERE THUNDERSTORM WARNING IS ISSUED FOR  
YOUR LOCATION?  
 
IF YOU ARE OUTDOORS, GET INSIDE YOUR HOME, A STRONG BUILDING,  
OR IN YOUR CAR. BOATERS SHOULD HEAD TO SHORE IMMEDIATELY.  
 
WHEN INDOORS, GO TO AN INTERIOR ROOM ON THE LOWEST LEVEL. STAY AWAY  
FROM WINDOWS AND EXTERIOR DOORS. DO NOT USE ELECTRICAL APPLIANCES  
AND AVOID USING THE TELEPHONE, AS LIGHTNING CAN TRAVEL THROUGH  
ELECTRICAL AND TELEPHONE LINES.  
 
IF YOU ARE DRIVING, SAFELY PULL OVER TO THE SIDE OF THE ROAD UNTIL  
THE STORM PASSES. HEAVY RAIN FALLING FROM ANY THUNDERSTORM CAN FLOOD  
ROADS QUICKLY, SO NEVER TRY TO DRIVE THROUGH AN AREA WHERE WATER  
COVERS THE ROAD, EVEN IF YOU THINK IT IS SHALLOW. WATER MAY SWEEP  
YOUR VEHICLE AWAY IF YOU ATTEMPT TO DRIVE THROUGH IT.
