A Sandy Update

Sandy is now off the Jersey shore, as indicated above.  Amongst the amazing observations is a the rapid increase in significant wave height to more than 30 feet at buoy 4408, which is located about 200 km east of Long Island.

The Battery in NYC peaked at about 9 feet above Mean Lower Low Water (MLLW) during the morning high tide, but the next high tide is expected to be worse.

Jeff Master's Blog suggests that the peak during Hurricane Irene last year was 9.5 feet and that the record is 10.5 feet.  Thus, the next several hours are the most critical with regards to the storm surge.  Let's hope the forecast is overdone.
