The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.
One resident in Coventry said the wind had brought down ridge tiles from their semi-detached house, smashing the sunroof and other parts of their new car. ... cost her more than £1,000 to fix ...
A unique feature of the International Fujita scale compared to the Fujita or Enhanced Fujita scale is a new damage indicator based on measured wind speeds. For the IF scale , only wind speeds measured at or below 10 metres (11 yd) can be used to determine a rating.
From these wind speed numbers, qualitative descriptions of damage were made for each category of the Fujita scale, and then these descriptions were used to classify tornadoes. [ 9 ] At the time Fujita derived the scale, little information was available on damage caused by wind, so the original scale presented little more than educated guesses ...
Flood damage coverage is not typically included in homeowners insurance policies, Allstate states, but if your roof is damaged due to wind or hail and rainwater gets into your home, your ...
A tornado near Red Rock, Oklahoma, was monitored by scientists using a portable Doppler weather radar, an experimental radar device that measures wind speed. Near the tornado's peak intensity, they recorded a wind speed of 115–120 meters per second (260–270 miles per hour; 410–430 kilometers per hour).
[4] [5] The round design allows the wind to blow around the home, reducing the build-up of pressure on one side. [6] Additionally, with the roof and floors built using a radial truss array, that allows any potential energy from sustained winds to disperse across the entire structure instead of building up in one area.

The CME Hurricane Index, an innovation developed by the reinsurance industry provides contracts that are based on a formula derived from the wind speed and radius of named storms at the point of U.S. landfall. Enron Corporation was one of the first to explore weather derivatives, through its EnronOnline unit.
