PUBLIC INFORMATION STATEMENT  
NATIONAL WEATHER SERVICE NEW YORK NY  
600 AM EDT MON MAY 25 2015  
   
..NATIONAL HURRICANE PREPAREDNESS WEEK IS FROM MAY 24 TO MAY 30
 
 
PLEASE JOIN THE NATIONAL WEATHER SERVICE FORECAST OFFICE IN UPTON  
NEW YORK IN OBSERVING NATIONAL HURRICANE PREPAREDNESS WEEK.  
 
TODAYS TOPIC IS STORM SURGE.  
 
STORM SURGE IS THE DEADLIEST HAZARD ASSOCIATED WITH HURRICANES. IT  
IS AN ABNORMAL RISE IN THE SEA LEVEL PRODUCED BY WATER BEING PUSHED  
TO THE SHORE BY THE FORCE OF THE WIND. THIS ADVANCING SURGE COMBINES  
WITH THE NORMAL TIDE LEVELS TO CREATE A STORM TIDE. TO MAKE MATTERS  
WORSE...WIND DRIVEN WAVES ARE SUPERIMPOSED ON THE STORM TIDE AND  
BATTER STRUCTURES INCLUDING BOATS RIGHT ALONG THE COAST.  
 
STORM SURGE IS NOT JUST A COASTAL EVENT...IT CAN TRAVEL WELL INLAND  
WITH DEVASTATING CONSEQUENCES. HOW MUCH STORM SURGE YOU WILL  
EXPERIENCE DEPENDS ON THE HURRICANES TRACK...FORWARD  
MOTION...MAXIMUM WIND SPEED AND SIZE.  
 
BECAUSE MUCH OF THE UNITED STATES DENSELY POPULATED ATLANTIC AND  
GULF COAST COASTLINES LIE LESS THAN 10 FEET ABOVE MEAN SEA  
LEVEL...THE DANGER FROM STORM SURGE IS TREMENDOUS. THUS...IF YOU  
ARE ASKED TO EVACUATE...YOU SHOULD DO SO WITHOUT DELAY OR HESITATION.  
 
BACK IN 2012...HURRICANE SANDY TOOK A TRACK FAVORABLE TO PRODUCING A  
HISTORIC STORM SURGE ACROSS THE REGION. THE HARDEST HIT AREAS WERE  
ADJACENT TO NEW YORK HARBOR AND THE SOUTH SHORE OF LONG ISLAND WHERE  
A STORM SURGE OF 9 TO 12 FEET PRODUCED WATER LEVELS OF 4 TO 8 FEET  
ABOVE GROUND LEVEL...KILLING NEARLY 40 PEOPLE AND DESTROYING MANY  
HOMES AND BUSINESSES.  
 
ANOTHER HISTORIC STORM SURGE EVENT WAS THE LONG ISLAND EXPRESS OF  
1938. THIS CATEGORY THREE HURRICANE FEATURED A STORM SURGE OF 10 TO  
12 FEET...WHICH KILLED 600 PEOPLE ON LONG ISLAND AND ALONG THE  
SOUTHERN NEW ENGLAND COAST.  
 
BEGINNING WITH THE 2015 ATLANTIC HURRICANE SEASON...NOAA'S NATIONAL  
HURRICANE CENTER WILL ISSUE THE POTENTIAL STORM SURGE FLOODING MAP  
FOR THOSE AREAS AT RISK OF STORM SURGE FROM A TROPICAL CYCLONE. THIS  
NEW MAP WILL SHOW GEOGRAPHICAL AREAS WHERE INUNDATION FROM STORM  
SURGE COULD OCCUR AND HOW HIGH ABOVE GROUND THE WATER COULD REACH IN  
THOSE AREAS. THIS PRODUCT WILL BE FIRST ISSUED WITH THE ISSUANCE OF  
A HURRICANE WATCH...AND IN SOME CASES...WITH A TROPICAL STORM WATCH.  
 
NOAA'S NATIONAL HURRICANE CENTER WEB SITE HAS LINKS TO HELP YOU  
DETERMINE YOUR VULNERABILITY TO STORM SURGE.  
 
BE PREPARED THIS HURRICANE SEASON...AND VISIT HURRICANES.GOV AND  
READY.GOV/HURRICANES.
