Hurricane Sandy is moving northeast and is a category one system at the current time, having been upgraded back. Sandy's movement is already south of the track many global models have given her and she has not even crossed the latitude of the FL/GA border yet. Many models had her doing so by now ... So she's south of the global model track...
TWS-TFM has ensembles, which are small tweaks in the system at different levels of the atmosphere to give "alternative" outcomes.
TWS-TFM is an independent model here at The Weather Space.com -
Here are plots ...
TWS-TFM1 - Wider track into the Atlantic and into Eastern Long Island under Rhode Island, which puts that area in the worst of it on the way to NYC ...
TWS-TFM2 - Straight into Long Island, with no mercy for the area on the way to NYC ... it would still be real bad for Rhode Island upwards ...
TWS-TFM3 - Into New Jersey's Northern Coast, around Long Branch with the worst surge and storm placement for NYC ...
These ensembles target an area from Central NJ to Rhode Island still, the center point of the surge on all of them is Long Island and NYC ...

Hurricane Sandy is holding its own against high wind shear of 30 - 40 knots, and has regained its Category 1 strength after falling to tropical storm strength early this morning. Sandy is a massive storm, with tropical storm-force winds that span a 660-mile diameter area of ocean from a point even with central Florida northwards to a point off the central North Carolina coast. Twelve-foot high seas cover a diameter of ocean 1,000 miles across. A buoy 150 miles east of Cape Canaveral, Florida reported sustained winds of 63 mph, gusting to 76 mph, at 9:43 am EDT. Another buoy about 100 miles east of the coast of Georgia reported sustained winds of 69 mph at 11:52 am EDT. Due to the high wind shear and interaction with a trough of low pressure to Sandy's west, the storm has a rather unusual structure, with the strongest winds on the southwest side of the center, but a larger area of tropical storm-force winds to the northeast of the center. Satellite loops show that the low-level center of Sandy is partially exposed to view, with a small clump of heavy thunderstorms near the center. Most of the storm's heavy thunderstorm activity is on the storm's west side, in a thick band several hundred miles removed from the center, giving Sandy more the appearance of a subtropical storm rather than a hurricane.

Forecast for Sandy
Wind shear is expected to remain a high 30 - 40 knots for the next two days, as Sandy interacts with a trough of low pressure to its west. The high shear should keep Sandy from intensifying the way most hurricanes do--by pulling heat energy out of the ocean. However, a trough of low pressure approaching from the west will inject "baroclinic" energy--the energy one can derive from the atmosphere when warm and cold air masses lie in close proximity to each other. Sandy's drop in central pressure from 969 mb at 5 am to 960 mb at 8 am this morning may be due, in part, to some baroclinic energy helping intensify the storm. This sort of effect helps spread out the storm's strong winds over a wider area of ocean; Sandy's diameter of tropical storm-force winds are predicted to expand from 660 miles to 760 miles by Sunday afternoon. This will increase the total amount of wind energy of the storm, keeping the storm surge threat very high. This morning's 9:30 am EDT H*Wind analysis from NOAA's Hurricane Research Division put the destructive potential of Sandy's winds at a modest 2.3 on a scale of 0 to 6, However, the destructive potential of the storm surge was exceptionally high: 5.2 on a scale of 0 to 6. Sandy's large wind field will drive a damaging storm surge of 3 - 6 feet to the right of where the center makes landfall. These storm surge heights will be among the highest ever recorded along the affected coasts, and will have the potential to cause billions of dollars in damage. The latest set of 00Z (8 pm EDT) and 06Z (2 am EDT) computer model runs have come into better agreement on the timing and landfall location of Sandy. Our two top models, the ECMWF and GFS, both call for landfall between 10 pm Monday night and 4 am Tuesday morning, with the center coming ashore between Delaware and New York City.
A multi-billion dollar disaster likely in the U.S.
I expect Sandy's impacts along the mid-Atlantic coast and New England coasts to cost at least $2 billion in insured damage and lost business, and there is a danger the storm could cost much more. Steve Bowen, meteorologist for insurance broker AON Benfield, put it this way for me this morning: "Given the level of losses associated with Irene last year and the current projections of extended high wind, heavy rainfall, coastal surge and an inland flooding threat for many of the same areas with Sandy, it would not come as a complete surprise to see a multi-billion dollar economic loss." Sandy should bring sustained winds of 50 - 70 mph with gusts over hurricane force to a large section of coast. With most of the trees still in leaf, there will be widespread power outages due to downed trees, and the potential for a billion dollars in wind damage.
