The Enhanced Fujita Scale rates the strength of a tornado
- The Moore, Oklahoma, EF5 tornado occurred on May 20, 2013, earning the top ranking on the Enhanced Fujita Scale.
- The Enhanced Fujita Scale assesses tornado strength by using damage indicators and degrees of damage estimated by NWS meteorologists.
- Tornadoes are rated from EF0 to EF5, with EF4 and EF5 being classified as violent and accounting for only 2% of all tornadoes.
- The EF scale estimates wind gusts to determine tornado strength based on different points of damage along the suspected path.
- The original Fujita Scale was updated to the Enhanced Fujita Scale in 2007 to better reflect damage in relation to wind speed and structural design.
- NWS meteorologists spend hours surveying tornado paths, identifying damage indicators and degrees of damage to determine the final EF rating.
- The history of the Enhanced Fujita Scale dates back to Ted Fujita's development of the original Fujita scale in 1971 for categorizing tornado intensity.
- An EF5 tornado hit Moore, Oklahoma in 2013, causing significant devastation, resulting in 24 fatalities and over 200 injuries.
- The EF5 tornado was on the ground for 40 minutes, covering 14 miles and reaching a width of 1.1 miles.
- The Enhanced Fujita Scale is crucial for meteorologists to rate tornado strength accurately based on damage assessments.
