Here's an animation from Weatherbell. I think it's the NAM, so I don't know if it's worth watching... I know how NAM is discounted and not considered reliable in this context. But the deepening it shows is pretty striking and worrying.
The commenter who posted this at Wunderground added this brief note:
4km WRF ARW-core: watch eye wobble & storm tightens hours 36-48

The NHC site page for Sandy has a storm surge exceedance map that you can zoom down to street level. http://www.nhc.noaa.gov/refresh/graphics_at3+shtml/031332.shtml?gm_esurge#contents You can see the water is predicted to pile up on the western end of Long Island. I'm not very familiar with the city there, but I've read the flood walls in that area are only like 5f above mean sea level, and the surge right there might overtop them. I think these are what kept Irene surge out of the subway system, but this surge could be higher. It used to be the NHC didn't publicize SLOSH runs until hurricane warnings were posted, but not they keep this cool exceedance map updated.

Can't sleep. So I'm back to reading stuff about Sandy.
Just saw an animation of what looks to be the 00Z GFS at Wunderground. Showing 936mb?!? Can someone else confirm that? I'm not good with models.
I should add that based on the caption to the picture, that's 51 hours out, at 03Z on Tuesday a.m.

Note that is at the 900mb level, not the surface.

Another post of the 00Z GFS. That loop is incredible. Is there any way this situation can get worse?

Ditto with the above - try as best to disconnect overnight and get some sleep. Being fresh (or less sleep deprived when the time comes) is important!

900mb isnt far from the surface when the storm's pressure is 936mb, 94kt winds at that level over Long Island and NYC is pretty scary...

Re: ATL: SANDY - Models
12Z GFS almost looks a bit stronger and farther south--a bit closer to Assateague Island than to Atlantic City--than 00Z...is it close to 935 mb? May someone post a clear graphic (with the original source included) like that of KBBOCA?

Does that track take it over DC?

I see a *tiny* southward shift, but not that far south...maybe 15-20 miles.

12z Euro. No change on landfall in Central New Jersey but more strong from the 00z run.

What would that translate too? I converted the 121 knots to mph and it said 139 mph?????? That can't be right? Is it?

Re: ATL: SANDY - Models
That's at 850mb height level. I think it converts to around 90mph surface level but a pro met or someone with more experience would have to convert it more accurate for you.

No, that's correct. Its at the 850mb level though, so there would be a reduction involved in calculating surface winds. I'm not sure exactly what it is, but I'm sure someone on here knows.
