I didn't see it mentioned here but I've seen it reported previously: what makes NYC's situation worse is that it sits at the "bottom" of a funnel formed by NJ and Long Island. That is, a storm on a particular path would push the stormsurge up the funnel, effectively multiplying it (i.e., increasing it's depth and power). It's not an if question. It's when.
