Hi! Just got back from T&C on Friday.
We stayed on Provo and overall, the resorts are up and running. Beaches re-opened the first or second week of November which I think was the last one. Locals on Provo were telling us that Grand Turk is a mess. The cruise center is repaired and up and running but that's about it. Apparently the water sanitation system was badly damaged and has not been repaired. There actually is an investigation underway to find out exactly where the government relief funds went (apparently around $6 million was given to Grand Turk).
We dove mainly dove around West Caicos (spent a day at French Cay) and the reefs definitely have been knocked around. Almost every West Caicos site had sponges rolling around and a few coral heads had been moved. Not everything was trashed though - we saw some large barrel sponges and tube sponges that were still intact. The reef had some silt/run-off on it yet so it wasn't quite as vibrant as when we had been there 2 years ago. Walking along the southwest harbour bluff, a lot of broken coral, sponges, etc. were washed up on the nearby shore (we actually found whole sea fans on the top of the bluff ). There had been some significant swells early on in our trip so while it sucked to be kept topside, it helped clean off the reef. French Cay looked better - less silt and more soft corals were in better shape.
