The National Weather Service (NWS) in Grand Forks, N.D., reevaluated a tornado from June 20, 2025. Completing additional surveys and working extensively with wind damage experts, the new estimated maximum wind speed is greater than 210 mph, making it an EF5 on the Enhanced Fujita tornado scale.
This is the strongest tornado to touch down in the United States since the Moore, Okla. twister on May 20, 2013.
June 20, 2025, was an active day of severe weather in the Plains. Meteorologist Carl Jones, with NWS Grand Forks, explained that 22 tornadoes touched down that day in North Dakota.
He added, “This is also a preliminary number that may yet change as we continue to scour satellite imagery and sift through damage reports (still!) and assess whether it was tornadic or not – much further complicated by the fact that large area within the state experience significant damage from the derecho in the same areas that saw tornadoes.”
The tornado south of Enderlin, N.D., was a strong tornado. “The initial storm damage survey team found severe damage consistent with an EF3 or greater tornado with a preliminary estimated peak wind speed of 160 mph.”
However, Jones says that wasn’t the end of it. “A Quick Response Team (QRT), a team of wind damage experts, was assembled and agreed that given the Enhanced Fujita (EF) Scale damage indicators available, there were points consistent with high-end EF3, if not greater.”
Meaning additional investigation was needed, and the tornado could end up being rated higher. A train derailment south of Enderlin, ND during the time of one twister was a big prompt for the reevaluation. Collaborating with structural damage experts, namely the Northern Tornadoes Project at Western University’s Canadian Severe Storms Laboratory, they were able to model object trajectories and the force/wind required to move such objects.
This was important and Jones says, “Allowed for the capability to assess the train derailment of 33 train cars, including several full grain cars that were tilted over and tanker cars that were lofted off the track, that yielded the EF5 intensity rating.”
Additionally, other indicators for the reevaluation included high-end tree damage near the Maple River, east of Enderlin, as well as a foundation to a farmstead that was swept clean with debris scattered downwind.

The tornado was on the ground for just under 20 minutes and traveled just over 12 miles. It reached 1 mile in width. While no injuries were reported from this twister, three deaths occurred.
May 20, 2013 EF5 tornado Moore, Okla.
What makes this newly revised classification of the twister so impressive is that this is the first EF5 tornado in more than twelve years. The last time a tornado this strong touched down in the United States was on May 20, 2013, in Moore, Okla.
A tornado outbreak occurred in the afternoon and evening of May 20, 2013. Several supercell thunderstorms developed during the early afternoon in central Oklahoma. One of these storms rapidly intensified, producing a tornado that touched down on the west side of Newcastle, Okla. The tornado became violent and then tracked across the city of Moore and parts of south Oklahoma City. It was on the ground for approximately 40 minutes before finally dissipating.
This photo was taken around 3:00 pm CDT on May 20, 2013 from Carrington Lane in the Carrington Place addition in northwest Norman, which is located between 36th Ave NW and 48th Ave NW, and south of Franklin Road. The view is looking northwest towards the corner of Franklin Road and 48th Ave NW. This photo was provided courtesy of Jenny Hamar via NWS.
The tornado caused catastrophic damage in these areas and was given a maximum rating of EF5. The tornado claimed 24 lives, injured scores of people, and caused billions of dollars in damage.
