Near-record central pressure of 940 millibars (27.76 inches) when the center of the storm was about 35 miles off the New Jersey coast. This was the lowest pressure of any storm that has made landfall north of Cape Hatteras, NC. Hurricane Gladys in 1977 holds the record the for lowest pressure of 938 millibars (27.73 inches), a category 4 hurricane which never made landfall in the U.S. At landfall Sandy's central pressure was 946 millibars.

The combination of the hurricane-force onshore winds, the timing of high tide near Sandy's landfall, a full moon, and coastal topography resulted in destructive storm surge from Virginia to Rhode Island. The storm surge along the Virginia coast was 4 to 6 feet. Of course, as we know the worst surge was near and just north of Sandy's center in New Jersey and New York.
Here are the most impressive and significant storm surges, measured as feet above normal average low tide:
- 14.38 ft at Kings Point, NY
- 13.88 ft at The Battery, Lower Manhattan. This broke the old record of 10.02 feet reached during Hurricane Donna in 1960.
- 13.31 ft at Sandy Hook, NJ

Of course, the book hasn't closed on Sandy. At its peak 8.5 million customers in the eastern U.S. were without power. As of tonight there are still 1 million without power, and the impending storm tomorrow will likely slow the restoration of power and may cause additional outages.
Sadly, Sandy has been responsible for 170 deaths with 111 of those in the U.S., 2 in Canada, and 57 Carribean.
