Should be fine cramming them all into the 2nd floor. There is probably roof access worst case.

Yep. The wind isn't that bad if they do have to go on the roof.

Yeah, the old “vertical evacuation” trick.
Some people, including a NO city councilwoman, tried that during Katrina at, IIRC, the high rise Hilton hotel.
Result was hysteria when all of the facade’s plate glass windows blew out. Huge shards of glass blew into hotel rooms. Furnishings were hurled about.
People were running to hide in the stairwells.
The ground floor was under water, electricity out, pitch dark.
Good fun for all.
100+ mph wind ain’t nuffin’ nice.
Most of the dead in Katrina did NOT drown; they were killed by blunt force trauma—hit by flying debris.
