New Storm Surge Map Shows Coastal Risk

This is the closest view I could get on the map.  The scenario is for a
Category 4 storm.  You can see areas of the Bronx and Pelham Park across
 to the west and northwest across Long Island Sound from the Long Island
peninsulas.
The National Oceanic and Atmospheric Administration has released a new online map product that provides storm surge potential for the entire east coast for different hurricane category strengths.  Check out the map here.  The map is very different from evacuation maps in that the focus is solely on how deep the storm surge could be.  It's a great product, but it does not allow one to zoom in to the neighborhood level.

Since I live on the coast, I looked at my own neighborhood and I was unable to go beyond a regional county scale view.  I also noted that based on my own neighborhood, the levels were very unrealistic.  We've been through some bad storm surges since we've moved here and the extent of the surge was not ever as high as mapped.  However, it is worth noting that the map is meant to be a worst case scenario.
