No commercial flights in or out, the airport was too badly damaged. The only planes able to get there are seaplanes.
There aren’t many places intact enough to shelter in, and the few there are are swamped with people. They’re doing what they can, and helping people when possible, but Irma has weakened enough buildings that it might not matter that Jose is weaker.
Then they should move to the south side of the island. It’ll be in the lee of the wind. Find a place no lower than 20 foot elevation.
If the hotel is concrete even the shell’s interior, stairways, etc. are better than out in the open somewhere.
Do they have satellite phones? How is information supposed to reach them. I don’t see how cellular is working after Irma.
