GRAND FORKS, N.D. – Up to seven tornadoes may have touched down Saturday in southeast North Dakota and western Minnesota, the National Weather Service said Sunday. No injuries were reported in any of the tornadoes.

Crews Sunday surveyed damage from two of the twisters, including a strong one that hit near Tyler, N.D., about 7 p.m. Saturday. Greg Gust, in the weather service’s Grand Forks office, said that tornado was on the ground for about five miles and had wind speeds greater than an EF3, which range from 136 to 165 mph.

“It was scouring a sugar beet field and pulling sugar beets out of the ground,” he said.

Crews also looked at damage from a tornado in Grant and Douglas counties in Minnesota, but Gust said it caused little damage to buildings. It was on the ground for 19 miles and had wind speeds of 86 to 100 mph.

More assessments were planned for today as the weather service worked to confirm the exact number of tornadoes.
