but aren’t skyscrapers in Miami designed to withstand CAT 5 hurricanes with winds up to 200 MPH?
The wind load design for high rise is probably adequate but the damage from airborne material will do lots of damage. My recollection of the design pressure is more like that for a 150 mph expressed in pounds per square foot
the main problem though will be storm surge and high water. the large and many residential structures essentially right on the water will be wiped away or severely damaged. The same will be true for the lower floors of high rise structures.
Watch the opening scenes of CSI Miami and think of a 5’ or 10 foot storm surge
