So looking at all the Irma footage...
Havana got badly flooded. Waist high in the streets. Their power grid took major damage and won't be back up any time soon.
Haiti - while it avoided the worst of the storm - has a very fragile power grid, so even a light swipe is likely to make things very bad.
In the Keys, it looked like Marathon was mostly underwater. I know that the roof came off the operations center for emergency responders in Key Largo.
Huge storm surge in Miami. Brickell Avenue was waist deep in water.
Just hit Marco Island on the gulf coast, and it's going into Naples now. I'm afraid there's going to be a massive (10 to 15 foot) storm surge in the St. Pete/Tampa area. That's going to cause heavy flooding similar to Harvey.
They're getting gusts from 130 to 142 as it goes into Naples. That's really bad.
