I doubt I would get any seawater at my location. I'm probably far enough north of the city and far enough inland. It would probably take something more like an asteroid impact into the ocean to deliver actual seawater to my location. What would impact us the most would be the disruption of goods and services due to the crippling effect of the massive flooding in nearby areas. Places like Long Island, Brooklyn, Manhattan, areas near Long Island Sound, etc. would experience serious problems.
