Hurricane Wind Risk

A jurisdiction has high hurricane wind risk if it is within the hurricane prone region as defined in the 2015 and later IBC:

  • The U.S. Atlantic Ocean and Gulf of Mexico coasts where the ultimate design wind speed, Vult, for Risk Category II buildings is greater than 115 mph (51.4m/s);
  • Hawaii, Puerto Rico, Guam, Virgin Islands, and American Samoa.

A jurisdiction also has high hurricane risk if it is located within the Commonwealth of the Northern Mariana Islands (CNMI), due to its typhoon history and its proximity to Guam.
