Well damn! Impressive indeed. I know with Irma we had a big surge that came quickly at our house in Cudjoe Key and ripped like a mother. Then reversed and ripped our front gate from the rails and took all our crushed coral with it.

Damn. I have never seen that. Appreciate the info.

This is believed to be the initial tidal wave from Hurricane Katrina.
A hurricane is a relatively slow moving and gradual but constantly changing weather event spread out over many miles that came from hundreds of miles away. Why would it be carrying a wall of water at any particular point within the storm that hadn’t fallen over on itself or spread out ahead of the storm?

This photo is real, but the "wall" is from water topping a protection levee, not a brute wave crashing at the shore.

You can watch videos of Katrina's surge on youtube if you'd like. Those videos show how it works pretty well. It's a slow and steady rise at first but then usually right before the eye comes ashore it comes up very fast and the waves are even higher on top of it.

That’s the levee being topped. There’s a big ole hunk of dirt under that “wave”.

Storm surge is the measurement of water elevation over what was expected to be the hi tide for the day at a given measurement location based on the moon’s gravitational pull.
Essentially it is the additional water pushed inland by the wind. It occurs on a “daily” basis not just on days when there are hurricanes.

I know it’s semantics but what you’re describing is essentially wave mechanics not “storm surge”. The surge is the amount of water which is why it’s measured in feet. The damage created by waves are just just that hydraulic forces created by gravity when the wave grows past the breaking point which is the same action you see at the beach on any given day.

storm eye pushes water like a big ship...

I’ve seen storm surge in varying degrees in coastal regions.
It always has come in waves
Each wave bringing higher water and bigger waves
As the water gets higher and higher, the impact of that moving water just gets more powerful.
I watched it come in against a bulkhead and it would pound relentlessly and each time it came off the bulkhead, it gained energy and drove a hole in the ground on the sides of the bulkhead which became clear after the water subsided. It was dramatic to see the ground loss

Again what you are describing is the wave energy which is not storm surge. Storm surge is the elevation of water above what is predicted based on gravity induced tidal movements. When they say a 20 foot storm surge it does not include wave height. It is measured as if it were flat like a lake. Here is a link to NOAA’s website that demonstrates what is considered storm surge.

Yes there is a presence of large waves and these waves harness an abundance of hydraulic energy that create a significant amount of damage to coastal structures. However, by definition this is not storm surge. It is damage due to waves. Storm surge is the 10 foot lake of water that have sitting on top of what is typically dry land.
