... 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.
