I've seen steady reporting about Puerto Rico since Hurricane Maria but it's been exactly that -- "about Puerto Rico" rather than "from Puerto Rico". Everybody seems to think it's bad, but it's really hard to say how bad. I think the major contributing factor to how the situation is being reported is that most of the cell towers (90%?) are out of action, and presumably land lines have also been seriously affected.
It's also been nearly a week. In all fairness though, it seems like the airports are either shut down or operating at greatly reduced capacity, so it's hard for reporters to get in.
The military isn't giving up seats on military flights to members of Congress today because they need the space for vital supplies and personnel, which is one measure of how hard it is to get into PR right now.
I just got out of PR Tuesday. I tried to get a ferry to DR to do this exact thing in reverse to get into the mainland and was informed the ferries are all out of service.
I saw an article earlier today about how hard it’s going to be to rebuild the electric grid (effectively REPLACE it because it’s 80% gone) that said that for at least a while the airport didn’t have radar and flights had to be confirmed for landing before they could even take off which was adding a massive delay to any attempt to get to the island.
