Storm Surges Hurricane storm surge causes approximately 90% of all storm deaths and injuries and much of the damage. What is the #1 cause of deaths by hurricanes?

Category 1 -- Winds mph Category 2 -- Winds mph Category 3 -- Winds mph Category 4 -- Winds mph Category 5 -- Winds over 155 mph (these are VERY rare)

The southern shore of Long Island is most vulnerable to storm surge because hurricane landfall will first occur there and the low elevation will allow sea water to move well inland.

The Long Island Express The 1938 hurricane produced the equivalent $41.5 billion in losses today. 600 to 700 people were killed, people were injured 75,000 buildings were damaged 20,000 automobiles destroyed, and 3,000 boats sunk.
