  It is shown that the physical damage resulting from severe weather phenomenon
such as hurricanes and tornadoes encapsulated in various scales such as
Saffir-Simpson, TORRO and the Enhanced Fujita Scale, and measured by the Power
Dissipation Index can be predicted using the concept of the Peak Virtual Power.
This corresponds to the maximum rate of Entropy production, which is considered
to be the basic physical principle underlying the damage.
