This is interesting.. in 1976, we went through SuperTyphoon Pamela on Guam. Guam is only 10 miles wide at the widest point.. and about 55 miles long (I thnk). I've seen a number of different values for the winds.. from sustained at 165 - 190 mph. Anyway, it took 12 HOURS for it to clear the island .. and we were in the eye for 3 hours. I was a shelter nurse for the island Public Health, and remember that quite well.. The sight the next morning was unbelievable.. we were fortunate that we lived in Navy housing.. and we used to joke that they were built by the same people who built fall-out shelters, they were like brick block houses with flat roofs!! Anyway, it sounds like this scenario must be a bit unusual.. they say it moved very slowly once it hit the island. But it must have been a very large storm, too..
