That's the near shore buoys, check out the Hotel, Station 44004, 81.3F. And if you look at the edge of the shelf(the 300-3000' lines), the water is in the mid to high 70s, and it looks like some warmer water is spinning off the Gulf Stream heading inshore. On the satellite map that 'worm' shaped trench at the 300' line is the Hudson Canyon which is about a 100 mile run from Sandy Hook. Also, if you look at the recent history at the Hotel Buoy, it's trending up, a bit. This is right at the peak water water temp time offshore of Jersey. Out at the Hudson Canyon, the water temps stay above 70 for the most part until December. It can be snowing on land, but if you run to the Canyon, you can catch Tuna and Mahi in shirtsleeves sometimes until or after Christmas.
Bad as that sounds, the folks in Dorchester and Talbot and Queen Anne Counties (MD) are really screwed if this thing tracks as most of the predictions are calling for. I'm 60 feet above msl but they are 5-8 above msl at best; most right along the water - and there will only be 2 ways off the whole Peninsula, Chesapeake Bay bridge and the bridges over the C & D Canal that bisects northern Delaware. (I can't see anyone trying the Chesapeake Bridge Tunnels!)
