F5 tornado wind speed MINIMAL DAMAGE: Some damage to chimneys, TV Moderate tornado: 73-112 mph: The lower limit is the beginning of hurricane wind speed; peels surface off roofs; mobile homes pushed off foundations or overturned; moving autos pushed off the roads; attached garages may be destroyed. Wind speeds between 40 to 72 mph (64 to 116 km/h) The lower limit is the beginning of hurricane wind speed; peels surface off roofs; mobile homes pushed off foundations or overturned; moving autos pushed off the roads; attached garages may be destroyed. Considerable damage. F2: Significant tornado: 113-157 mph: Considerable damage. F0 Tornado. Moderate tornado: 73-112 mph: The lower limit is the beginning of hurricane wind speed; peels surface off roofs; mobile homes pushed off foundations or overturned; moving autos pushed off the roads; attached garages may be destroyed. The Fujita Tornado Scale, usually referred to as the F-Scale, classifies tornadoes based on the resulting damage. Although the Fujita scale itself ranges up to F12, the strongest possible tornadoes are in the F5 range (originally estimated to be between 261 to 318 mph). A tornado rated an F5 had winds great than 261 MPH. T. This scale was developed by Dr. Different wind speeds may cause similar-looking damage from place to place -- even from building to building. Below is a brief description of each type of tornado on the Fujita scale. MINIMAL DAMAGE: Some damage to chimneys, TV . A tornado with wind speeds greater than 319 miles per hour (513 km/h) is possible, as the 1999 Bridge Creek-Moore Tornado did have 321 mph (517 km/h) winds, but that measurement was not near ground level. 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. Trees will be compeltely debarked and strong framed houses will be completely severed from their foundation. The damage from a F5 tornado is incredible, automobiles become flying missles that can be thrown over 110 yards. Without a thorough engineering analysis of tornado damage in any event, the actual wind speeds needed to cause that damage are unknown. Theodore Fujita (University of Chicago) in 1971. 1991 Andover tornado outbreak – Mobile Doppler weather radar used by storm chasers indicated wind speeds in the range of the F5 threshold, with winds up to 268 mph (431 km/h). For example, the Tri-State Tornado was an F5 tornado, which was one of the most violent and deadliest tornadoes in history. This method is a sliding scale 0 to 5 with 5 being the most violent. Pavement and ground scouring occurred, and a large oil rig was toppled.
