Great Gull Island, NY had sustained winds of 75 mph recorded at 4:30 pm on October 29, while the eye of the storm was nearly 250 miles south.
A storm surge of 9.4 feet rode into New York Harbor on top of a high tide to bring water levels to 13.88' above the normal low tide level at The Battery. This smashes the record 11.2 feet from the great hurricane of 1821.
A gust of wind 96 mph was recorded at Eaton's Neck, NY. Hurricane force wind gusts were reported in seven different states.
A buoy at Sandy Hook, NJ recorded 8.1' water level before it failed 1 hour prior to its high tide. It's estimated that the water would have reached 14.4', shattering the old record of 10.1'.
Sandy made landfall at 7:30 PM on October 29 near Brigantine, NJ with estimated winds near 80 mph. The minimum central pressure was 945 mb which is the second lowest pressure ever for a tropical or post-tropical storm north of North Carolina.
Tropical storm force winds extended 1000 miles across in diameter, making this the largest Atlantic tropical cyclone on record. Its size raised water levels from Florida to Maine, and produced high winds half way across the country - as far west as Wisconsin.
RECORD LOW PRESSURE
Sandy produced record low barometric pressures for Baltimore, Philadelphia, Atlantic City, Trenton, Harrisburg and Scranton.
12.83" of rain fell in Bellevue, MD, the highest for the entire storm. This is nearly four times its average October rainfall. Eight other locations received more than 11" of rain.
Sandy brought 2-3 feet of heavy snow along with blizzard winds to the mountains of MD, WV, NC and TN, creating widespread power outages.
The NWS doubled the frequency of all upper-air soundings, launching nearly 600 extra balloons that feed data into weather forecasting models. Hurricane Hunters flew 10 missions in over four days. GOES-14 satellite was repositioned and placed in rapid scan mode to see more of Sandy.
RECORD TROPICAL PRESSURE
Sandy had the second lowest pressure at landfall (945 mb) of any Tropical or Post-Tropical storm north of Cape Hatteras, NC.
