The path drawn at its surveyed width of 250 yards (0.14 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

This tornado touched down south of Mahnomen at 4:15 PM. The highest damage it caused was rated as an EF-2. Among the damage it caused as it continued across its 6 mile path was trees snapped and uprooted (both hard and soft wood), metal garage slid off its foundation and collapsed, crop damage, Quonset caved in on one side, roofing blown off homes, broken power line poles, and lifting fuel tankers full of 250 gallons of fuel and throwing them at a barn. Damage dollar amounts are estimated.

The wider storm

Surface low pressure system tracked across the North Dakota/South Dakota border creating an environment supporting the threat for low top supercells in Southeastern North Dakota into adjacent West Central Minnesota. Several low-top supercells developed and tracked along portions of the Minnesota Red River Valley. Portions of Norman, Polk, Becker, and Mahnomen counties saw multiple tornadoes. Large hail and damaging winds accompanied some of these storms, and flash flooding in some locations as well.

Began near Waubun (47.2500, -95.9400).
