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.
On its website, it said its general view was "that damage can occur even when the wind speed is lower than level 10 on the Beaufort scale", which starts at 48 knots, or 55mph.
The state increased performance criteria for wind-load provisions and adopted new wind provisions from the American Society of Civil Engineers. One important addition to the new code was the requirement of missile-impact resisting glass , which can withstand high-velocity impact from wind-borne debris during a hurricane.
The International Fujita scale (abbreviated as IF-Scale) rates the intensity of tornadoes and other wind events based on the severity of the damage they cause. [1] It is used by the European Severe Storms Laboratory (ESSL) and various other organizations including Deutscher Wetterdienst (DWD) and State Meteorological Agency (AEMET).
Typically, hail and wind damage is covered by a standard homeowners' insurance policy. However, the policy may have limitations. Check with your provider to see if you have higher deductible for ...
Wind speed on the Beaufort scale is based on the empirical relationship: [6] v = 0.836 B 3/2 m/s; v = 1.625 B 3/2 knots (=) where v is the equivalent wind speed at 10 metres above the sea surface and B is Beaufort scale number.
Damage to chimneys and television antennas; pushes over shallow-rooted trees. Severe thunderstorm criteria begin (58 mph (93 km/h)). Hurricane-force: 12–13 † 74–112 mph (118–181 km/h) Peels shingles off roofs; windows broken if struck by debris; trees uprooted or snapped; mobile homes severely damaged or overturned; moving cars pushed ...
The effects of Hurricane Ike in inland North America, in September 2008, were unusually intense and included widespread damage across all or parts of eleven states – Arkansas, Illinois, Indiana, Kentucky, Michigan, Missouri, New York, Ohio, [1] Pennsylvania, Tennessee and West Virginia, (not including Louisiana and Texas where the storm made landfall) and into parts of Ontario as Ike, which ...
