When assessing damage, important to distinguish between surge and wind damage (there was a lot of both here) on Abacos. The building Josh was in was a brick school which was basically demolished with a few partial walls standing. No way Josh uses a building in a category 5 for shelter unless he feels its a strong structure. Also saw a video from someone in a car driving past what was clearly catastrophic wind damage. From aerials alone though it can be hard to distinguish though, especially since most stuff is low lying there.
