NYC is NOT as safe as you think, unless you are just talking Manhattan, and even there, there are sections of the east and west sides that WILL flood. We will probably loose the Brooklyn Battery Tunnel in anything major due to tidal surge. NYC's current OEM building will be under water even in a class 1 hurricane (yeah - dumb, and THEY know it - new building will be ready sometime this summer - that one is NOT in a flood zone) - Booklyn and Queens will have some serious issues (Then again - they fit on the 'long island' scenario) - there are major issues in the Bronx - think Co-op city - that floods in a bad cat 1

http://www.nyc.gov/html/oem/pdf/hurricane_map_english.pdfI'll be involved with at least 1 drill this spring, and I know that there is another that will involve Nassau county too
In a big cat III or a IV - NYC figures they have to evacuate 1.25 MILLION people - they figure 1 million of those will be able to get shelter on their own - they figure on having to shelter between 100k and 250k people!
Trust me - It would NOT be fun and joy - the big worry scenario is the NY Bight scenario - Oh, that would be NO fun - that involves a fast moving storm of say high Cat III to Cat IV, coming up the coast, where the eastern eye wall hits in NY Harbor at High tide. part of the real fun of this scenario is that the WESTERN eye wall hits shore a bit south of us in NJ - remember, that when the eyewall hits land, the storm starts to break up, and rainfall increases. NJ, and the NYC northern suburbs are VERY flash flood prone - flooding is fairly common (Hi Marty) - now we have a problem - Parts on PA, much of Northern NJ, Westchester, Rockland, Orange in NY, and parts of CT are ALL screaming for help due to flooding - Nassau, Western Suffolk, and NYC are seriously short handed. Eastern Suffolk is busy duing mutual aide to western suffolk. Where does the outside aide come from - and how do they get through the river valleys on NY/NJ/PA/CT to GET to NYC/Long Island?
Can you tell that I've spent a bit too much time gaming this?
