The C.G. videos and pictures I saw were devastating. Many of the islands are privately owned with private mansions. The owners of those islands left before the storm and the damage is not yet known. 1 Island with a fairly large population is now uninhabitable. Just about all income on the islands comes from tourism and it is expected that the financial loss will be felt for a long time.
BTW, ALL the islands sustained damage to a greater or lessor degree.
