1. The downgrade of Sandy to a tropical storm was a mistake by NHC in my opinion. The pressure is falling, and Sandy will come in with the impacts like a hurricane is what I think is happening now. Sandy is going through the change from a tropical system to an extra-tropical system, so from a tropical sense, yes, Sandy is not really a hurricane, but from a meteorological sense, Sandy is getting bigger and the pressure is expected to fall to sub 950 mb. At that pressure, winds will be over hurricane force. The two images below show the GFS wind speeds in knots.
2. Sandy will be a dangerous storm coming in with a storm surge that will hit Long Island, the south coast of New England and even into New York City. The Jersey beaches to the Maryland beaches will be flooded and in some areas, the ocean is going into the streets.
A busy weekend for the Midwest and Ohio Valley as severe storms will hit ahead of the cold front.

Heavy thunderstorms to bring some locally damaging wind gusts. Tornadoes for Canada! It's the season for them!
A cluster of thunderstorms or perhaps an Derecho will produce a swath of damaging wind gusts across North Dakota into northern Minnesota.
The rains are underway across Texas so watch the flooding. Sniffing out a storm development along the East Coast.
