BVI

The website has a tremendous amount of information* should you wish to take a look. i.e. this map which shows the Eastern Caribbean airport/seaport access status. **

*From Sit Reports, shelter maps, air/sea port status map of Eastern Caribbean, damage reports from BVI, government statements, transportation infrastructure maps, humanitarian aid, requests for aid. Immense quantity of information in a single repository (chronological order; dated documents/maps).

I imagine they will update the maps as the opportunity arises.
