Interesting. Always wondered what the US would look like in a case like this.
Notable items:
Eastern Seaboard is pretty much gone, going as far inland as Washing, DC and Richmond, VA.
On the western side, the Puget Sound got a bit bigger, Portland and the valleys further south get turned into inland lakes, and the Bay Area flooded over into the Sacremento Valley.
South, Florida is gone. Full stop. The Mississippi River Valley becomes the Mississippi River Inlet. And the Texas coast moves about fifty miles inland, taking Houston and Corpus Christi with it.
