Size of breach at Fire Island NS, punched through by Hurricane Sandy, has mostly stabilized: USGS

A study finds that although the “wilderness breach” created by Hurricane Sandy in 2012 has reached a relatively stable size and location, the channel and shoals will keep changing in response to weather. Related research shows the breach isn’t likely to increase storm-tide flooding in Great South Bay.

A new U.S. Geological Survey study of a Hurricane Sandy-created opening between the ocean and Great South Bay at Fire Island National Seashore is one of the most detailed scientific examinations ever conducted of the early stages in the life of a barrier island breach. Computer modeling based on the study’s data finds that the breach has not significantly increased the projected level of storm-tide flooding in Great South Bay.
