Good Lord. 16 hours before landfall and look at that flooding. Unreal, and it’s only going to get worse.

It will get worse, but probably not all throughout the time between now and landfall.
Galveston’s getting what the rest of the Gulf Coast is getting, still well outside the eyewall.
When the eyewall comes ashore, so will the main surge. Till then, sea level will go up with the tide, but not much more.
Same thing happened during the 1900 hurricane. Galveston proper flooded to about 18 inches early in the morning, then the surge didn’t come ashore till 4 pm. Back then they had tall curbs, so the streets ponded, but not the sidewalks. Then around 4 pm, the levels went up at least 4 feet in 30 seconds, and beyond that, no-one was keeping precise records.
The biggest part of the destruction was due to wave action, which took out so many buildings on the Gulf side shore that the debris built a levee and protected buldings more than 10-15 blocks inland from wave action, they flooded in a relatively calm sea. The seawall will affect that dynamic, this time around, since it wasn’t built in 1900, but I’m not going to try to predict just how. Instead, I’m going to wait and see what happens.
YMMV.
good to see you :) Been in and out- trying to catch up now on this damn storm.

Thank you for the great recounting. I agree that the effects of the seawall are not known now. I hope it is very very helpful. I’m quite worried for sure anyway.
YMMV.
