Let me answer my own question...
From

"The wind will blow out windows and explode many homes, even those built to the existing 110-mph building-code standards. People seeking refuge from the floodwaters in high-rise buildings won't be very safe, recent research indicates, because wind speed in a hurricane gets greater with height. If the winds are 155 mph at ground level, scientists say, they may be 50 mph stronger 100 feet above street level."
If you read the building codes, you will see that the wind load design paramaters increase with the building height.
The question is...is the La code as hurricane oriented as the South floridia/Miamidade code.
In tall buildings, the damage will result from wind blown debris, especially roof gravel. The research was done bu Texas Tech..
