Tide, Wind and Thin Water
In the course of the visit we asked what the average range of the tides in the Sound is, and got one of those fun reactions that makes you realize you are REALLY out of your range: Essentially, there are no tides in the Sound; the outer banks being such a complete barrier, with few inlets, block any tidal effect.
…The pressure of that wind-driven tidal wave with no room for it to escape through the two or three inlets meant that it created a whole new inlet and washed across the banks from inside toward the ocean. … For an image of how this works, consider a big washtub filled to about 4″ from the top; pick one end up slowly until the water reaches the edge, then drop the edge you’ve picked up; what happens?
… Add to this that Pamlico Sound is essentially nowhere more than about 20 feet deep, and you can begin to grasp what happens when the wind blows at hurricane force across the ocean-equivalent of a puddle 1″ deep.
