I went through a typhoon in Okinawa in the 70's. I have no idea what "category" it was. I was in a supposedly "typhoon proof" structure--essentially a reinforced semi-tubular steel Quonset type building with 1/2" steel cables over it anchored in a concrete slab underneath. The building shook and rattled. At the height of the storm, a very heavy old window air-conditioner blew out of the window and came sailing 10 feet or so across the room, landing just short of my chest (I was lying on a medical exam table trying to sleep). We were well above sea level so there was no storm surge to worry about--just the wind. Anyway, it was all quite enough to convince me I would not want to "ride out" one of these storms in any conventional house.
