Actual Flooding caused by Superstorm Sandy
Predicted Flooding based on Hurricane Categories 1 through 4 - the darkest red represents the predicted surge from a Category 1 hurricane, the weakest hurricane and the most likely kind to hit NYC, through the lightest yellow, representing the predicted surge from a Category 4 Hurricane, the strongest hurricane, and the highest category storm likely to affect the north east. Category 5 hurricanes are typically thought to be not likely to retain their force in traveling up the eastern seaboard, and would be downgraded to a lower category before they ever would hit NYC, according to hurricane experts. But, hey, with climate change the way it’s been going, you never know. Compare this map with the map above of the actual storm surge, and notice that, in terms of storm surge at least, the storm surge was the equivalent of that of a Cat. 4 Hurricane, in most areas.
Thanks for sending, Kristen, and thanks also for working on the project and analyzing and compiling the data.
