There is actually a big difference in bleaching vs. what you se in Cozumel as related to Wilma.
Fortunatley, bleaching is not something we have had a problem with here.
When I was in BVI in December, the bleaching there was still very obvious and very sad. However, you could also tell that it was in fact recovering.
Just as a quick visual...think of the soft corals being white...literally. Sometimes only parts of it, others just the tips. As the water warms up, this goes away and the corals regain their natural color. It is a quick recovery in most cases. Think of it as a limp plant, then you water it...and in a few days it is vibrant again. It doesn't happen quite this quickly with coral, but you get the point.
If I ever get to my trip report and editing my pictures from the trip...I can show you some coral bleaching.
