Hurricane Sandy Intensifies as She Approaches Coast; Record Storm Surge Likely; Ocean City, Atlantic City NJ Under Water

At 943 mb lowest central pressure, Sandy will be the most powerful storm ever to make landfall in the Northeastern US. Described as a hurricane wrapped in a Nor’easter, the beating heart of this monster storm is now growing more powerful.

Sandy’s maximum winds have intensified to 90 mph, a rapid intensification from 75 mph just 12 hours ago. It is rapidly approaching the New Jersey shore and will likely make landfall there between 8 and 11 PM this evening. Water temperatures in the region are 5 degrees Fahrenheit higher than normal and a powerful dip in the jet stream is lending energy to this immensely powerful storm.

It is difficult to underestimate the potential coastal effects of this storm, particularly to the right of the center as it comes ashore. First, the storm is coming in at or near the time of high tide, an abnormally high tide amplified by the moon. So storm surges of 4-11 feet or more will pile up on top of an abnormally high tide of 2-4 feet above mean low water. In addition, water rises of around 4 feet or more are already being recorded along the coast. This water rise is being pushed against the coast by the wind and by the force of the approaching storm. The result is that many places may see water rises of 10 feet or more above normal. Given the intensity of this storm and the fact that it is continuing to intensify as it approaches the coast, these values may be underestimated.

Maryland, Delaware, New Jersey, New York City, Rhode Island, Connecticut, and Massachusetts may all experience the highest water rise values ever seen. Already, significant flooding has occurred along the Outer Banks and into the Hampton Roads area. Below is a picture of Chicks, a popular VA Beach restaurant being flooded out by Sandy.

After two days of battering, scenes like these have become commonplace in North Carolina and Virginia Beach. But what has happened there is just a prelude to what will likely unfold over the next few hours as Sandy comes ashore.

UPDATE

Reports are coming in that Atlantic City New Jersey is now under water (11:35 Oct 29).

UPDATE:

Some locations in New Jersey are reporting 9 feet water rises. Record rise for the region are 10 feet. The below image shows Ocean City flooding.

UPDATE:

Reports are coming in that the Point Pleasant, NJ dunes have been breached and sea water is rushing through city streets like a river (7:53 PM).
