This is just a big rip tide, we have several drownings everyyear
because of rip tide, particularly when wind speeds exceed 15 knts.
Whenever there is water pushed out of equilibrium it looks for the
return path of least resistence. That path will then have a channel
rushing by much slower water creating a swirl. These coastlines have
deep shelves and the added component you wont see, because in the
eastern U.S. the thermocline is far off shore, is that the tidal
surge from deep ocean elevated the thermocline, and when the wave
passed the thermocline receded drawing some of that surface return
downward with it.
There are critical differences between a storm surge and tidal
wave.
1. Storm surge, people generally have for warning and flee to higher
ground, the intense storm winds are a give away to experience coastal
dwellers. For tidal waves one has maybe 30 seconds of warning as the
prewave retracts from the shore line.
2. Storm surge is associate with alot of surface waves and the wind
drives the water inland, where it reaches natural channels where it
recedes, when the wind surge deminishes the wind has frequently
changed directions driving the water horizontally relative to the
shoreline where it finds natural channels. Tidal surge retracts,
finding whatever channel.
3. After a storm surge there are few witnesses or photoopportunities,
and you can see from florida, it took hours to detect that the
interstate had lost a bridge. Barrier island disappear, etc. In a
catagory 4+ hurricane, if you are alive it generally means you
evacuated from the coastline.
4. Hurricane obliterate the thermoclines, and do so by extending
surface waves to greater depths. If the thermoclines are close to the
surface they will obliterate a hurricane. This is why hurricanes
prefer the late summer, where the thermoclines are at their deepest
levels.
