I'm starting to come to agreement with 40/70 on his contrarian nature. None of these islands minus Barbuda have been completely decimated. Fact is at this current heading, it's going to interact with the mountains prior to hitting San Juan. The infrastructure will be damaged, but it isn't coming in from the northern part of the Island it's coming in from the South Eastern. It will be bad, and people will die, but this is a compact hurricane that doesn't have the size, or the punch Irma did at her maximum. The damage will be similar to the 7.1 in Mexico, and it will suck. However, this isn't going to be Biblical. We shouldn't let our imaginations run so wild with these storms. People who read the forums get the concept that it's going to be like Tuscaloosa, Moore, Joplin, but it's just not.
Also; If you'd do a little googling you'd see HAM radio operators are still in communication. Just because some services are out doesn't mean all are. http://www.arrl.org/news/radio-amateur-on-st-lucia-relays-reports-of-hurricane-devastation-on-dominica
