I haven't been to the southwest since the storms but I know what I see on the news and as I drive locally.
The train line between Exeter and Cornwall/Devon along the sea wall has been well and truly damaged. Much of the sea wall is gone, and emergency repairs were put in by placing many shipping containers along the shore. That was destroyed in the next major storm and I saw more devastation. The train rails were simply hanging in air. I believe that it will be many months until that is repaired.
The Somerset levels are still underwater with many villages linked by amphibious military vehicles for residents. Dutch pumps and English pumps are working their hearts out but the water is going down very slowly.
Many other rivers are mostly back in their banks but there is water rising from the land as it is super saturated.
Above the rivers life is just about normal. Many flooded businesses will take a long time to recover.
Perhaps others will chip in their experiences.
