The Enhanced Fujita Scale - What Is It?

ENHANCED FUJITA SCALE THE SCIENCE BEHIND TORNADO TRACKING WHAT IS IT? The Original Fujita Scale was devised in 1971 by Dr. Ted Fujita, a storms research scientist. The scale ranges from FO to F5, and is based upon the type and severity of the tornado. It has now evolved into the Enhanced Fujita scale, with a revised set of wind speed ranges. EF-O Estimated Wind Speeds: 65 to 85 mph. Observations: Light damage to roofing, siding, & gutters. Uprooting of shallow trees. EF-1 Estimated Wind Speeds: 86 to 110 mph. Observations: Moderate damages. Roofing is severely damaged, mobile homes turned over, exterior doors ripped off, & broken glass. EF-2 Estimated Wind Speeds: 111 to 135 mph. Observations: Considerable amount of damage. Missing roofs, housing foundations shifted, mobile homes decimated, large trees uprooted, cars lifted off ground. EF-3 Estimted Wind Speeds: 136 to 165 mph. Observations: Severe damages. Entire stories of homes destroyed, large-scale damage to large buildings, trains overturned, heavy cars uplifted, weak structures blown away. EF-4 Estimated Wind Speeds: 166 to 200 mph. Observations: Complete devastation. Whole houses are completely leveled, cars can thrown long distances, and small missiles can be penetrated. EF-5 Estimated Wind Speeds: Over 200 mph. Observations: Unbelievable damage. Strong frame houses blown away, high rise building deformation.
