Because over-engineering is a family habit, this little coop my DH built weathered Florence beautifully (it was unoccupied at the time), though it may have been a branch down that initially damaged the nestbox roof.
IMO, there are some hazards you can prepare for and some hazards you can't prepare for. Building with your region's worst weather in mind and locating your facilities wisely goes a long way.
IMO, if the chickens are in a strongly-built, well-anchored building located above likely flood levels they're probably safest right in their own coop where they won't be stressed by new surroundings and overcrowding.
I might move a "dollhouse" pre-fab, a meatie tractor, or a lightweight hoop coop to a sheltered spot in the angle of two buildings (or, at least, against the leeward wall of one), but I'd be leery of actually putting the chickens into a garage because of the lack of ventilation. The post-hurricane heat heat and humidity is HORRIBLE.
I don't live in a potential evacuation area, but if I did those trailer coops are awesome!
