N.D.–On Monday, a Bismarck National Weather Service damage assessment team surveyed parts of Stutsman, Lamoure and Dickey counties in North Dakota.
The only observed damage in southern Stutsman County was to trees about 3 miles west of Sydney. The damage was consistent with high thunderstorm winds around 70 mph.
A tornado was observed Sunday evening 3 miles north of Fullerton in northern Dickey County. The tornado impacted no structures and did no damage.
Significant tornado damage was observed in Lamoure County. The tornado touched down 7 miles southeast of Nortonville and moved southeast, lifting 6 miles south-southeast of Berlin.
No fewer than five farmsteads were impacted. One farmhouse was damaged beyond repair and one completely destroyed. Numerous power poles and trees along the path were snapped. Hail as large as 3 inches in diameter, fell along and outside the tornado path.
The National Weather Service in Bismarck has given this tornado an EF3 rating with wind speeds up to 165 mph. The rating of a tornado is based on the damage done. From that damage, the EF rating is assigned and from that EF number the wind speeds are determined.
