• Hurricanes form off the coast of Africa. These smaller storms gain strength in the warm Atlantic. (Video Optional)– http://www.youtube.com/watch?v=mm4m5f9ziA4
• How does this picture related to a storm surge and increase coastal flooding?

• New York City is located in a bottleneck for a storm surge. – If a large hurricane does hit New York City, it’s
location would make a storm surge much worse.
