I have a theory but people tell me I am wrong.
My theory is Long Island is very flat.
So as water comes up in the great south bay, it runs north.
So depending on how fast it comes up, it will only get so high.
The concept is like a swimming pool.
if my swimming pool is 10' deep from top to bottom and I fill my pool and keep filling it, the pool will still only be 10' deep.
The water will start to run into my yard and neighbors yard, etc, etc.
I think because long island is so flat, the water by the shore line will only get so deep.
I pray this is true becuase it means that what I saw for Irene in the AYC is as deep as it will get and the boat won't float!!!
