Experts Confirm First EF5 Tornado in Over a Decade Strikes the US
Rare North Dakota EF5 Tornado Marks Unprecedented Event in Over a Decade
EF5 Tornado’s Uncommon Fury Shocks Experts
The striking power of an EF5 tornado that ravaged eastern North Dakota in June has been officially recognized by the National Weather Service in Grand Forks. The exceptional tornado, initially rated EF3, was reevaluated and upgraded to the EF5 category after a detailed investigation. With winds exceeding 210 mph, it became the first such occurrence in the United States in over a decade, claiming three lives in its wake.
Unveiling the EF5 Tornado Path
The tornado initally unleashed its fury near Enderlin, North Dakota, situated about 40 miles southwest of Fargo. From there, it tracked northward for nearly 20 minutes, covering about 12 miles before dissipating near Alice. Experts assigned the EF5 rating based on the extensive damage assessed over the affected areas.
Destructive Impact and Analysis
The tornado’s devastation was evident, notably where it hurled an empty train car nearly 500 feet and toppled several loaded grain hopper cars. Additionally, large trees were reduced to barren stubs, and a farmstead suffered complete destruction. The rare EF5 event adds to a mere 60 recorded since 1950, underscoring its extraordinary nature.
Debate on the EF5 Frequency and Scale
The occurrence reignited discussion among scientists regarding the apparent “drought” of EF5 tornadoes since 2013. Recent research suggests that such rarity might involve inconsistencies in the damage rating scale rather than the tornadoes’ actual strengths. The study proposes a slight adjustment to the scale, lowering the EF5 wind speed threshold from 201 mph to 190 mph, aligning current data with historical records.
Understanding the Enhanced Fujita Scale
| EF Scale | Wind Speed (mph) | Description |
|---|---|---|
| EF3 | 136-165 | Severe damage |
| EF4 | 166-200 | Devastating damage |
| EF5 | Over 200 | Incredible damage |
Looking Forward in Tornado Classification
As discussions continue about refining the definitions within the Enhanced Fujita Scale, meteorologists and scientists alike remain vigilant in tracking severe weather events. The recent EF5 tornado in North Dakota has reset the clock on these rare events, lending new insights into their prediction and understanding.
