The Freeman Hurricane Damage Potential Scale is based on:

• Maximum Sustained Wind• Radius of Hurricane Force Winds• Central Pressure• Area of Significant Wave > 34 Feet• Hurricane Track• Hurricane Speed• Duration of Hurricane Force Winds• Exposed Offshore Properties

This is a preliminary scale and work continues on finding the factors that best define the damage potential factors

and the exposure to offshore properties.
