Just last year, Hurricane Irene pounded much of the East Coast with extensive surge and torrential rain. Storm tide levels in the New York City area reached around 8-10 feet, depending on the source, and some people say the water came within a few inches of topping the wall at Battery Park. Therefore, New York City barely dodged a bullet, as the subway system and critical electrical infrastructure could flood if the sea wall is overtopped with storm surge. We can only hope to dodge another bullet with Sandy! Note: The track for this storm is not yet available.
This is the fifth and final historic map of hurricanes that generated storm surge/ storm tide in the NYC area.
