Preliminary estimates for insured losses in Floridafrom Hurricane Wilma could range from $2 billion to $6 billion, according to Eqecat, Inc., the Oakland, Calif.-based catastrophe modeler.

The firm said it based its estimate upon landfall wind speeds of 125 miles per hour, following information provided by the National Oceanic and Atmospheric Administration.

Beyond wind damage to commercial and residential fixed structures==such as office buildings, factories, warehouses, and homes==Eqecat’s insured loss estimates include business interruption, which covers loss of earnings as a result of the destruction of property.

It also includes “demand surge,” which occurs when the demand for products and services to repair damages significantly exceeds the regional supply.

The company noted that such products and services may have to be brought to the region quickly from distant points, resulting in additional costs for transportation, packaging and manufacturing.

Eqecat said its current estimates excluded insured losses related to offshore platforms, commercial flooding, private and commercial automobiles and similar vehicles, as well as marine assets, such as boats.
