Yes, they did. If you download a program called Weatherbug it provides
you with your local weather, local radar, cameras, and some really
superb links. It is advertising supported, and the advertising can get
to be annoying, but the net is worth it. It has an interactive hurricane
tracker where you can track individual hurricanes for the past five years.

Not really. I spend a lot of time out in the Atlantic on my boat. I like
to get away from the day trippers, jet skiers, speeders, drinkers, and
other assorted dingbats so I usually wind up around 30-35 miles south of
Long Island near one of NOAA's ocean monitoring bouys. The Gulf Stream,
in the winter, is not too far away, and it is relatively warm. The bouy
reports water temps in the winter in the mid to low 40's. During the
summer, the Gulf Stream comes in closer to shore, and warms the water up
to the low to mid 70's.
That is how convection works.

I may have it in the basement.
