The National Weather Service calls the Monday outbreak of severe weather one of the most significant in the last 30 years in the area.

The first preliminary damage assessment for three of the tornadoes was released yesterday afternoon. The tornadoes in Morrill and Box Butte counties were not inlcuded in the preliminary assesment.

The tornado in northeastern Goshen County and West Central Sioux County was rated an EF-2, with estimated peak winds 111 to 135 miles per hour.

The damage assessment said that the tornado was 500 yards wide at its greatest strength, and was on the ground for about an hour and covered nearly 25 miles. The tornado first touched down at 5:09 PM about 15 miles north of Torrington, and lifted just after 6 PM about 8 miles south-southwest of Harrison.

The damage assessment team noted that a homestead sustained significant damage north of Torrington, and several three-quarter ton pickup trucks were vaulted several yards by tornadic winds. Several horses were seriously injured and three horses were killed in the tornado. One person also suffered minor head injuries. In Sioux county, significant damage was noted to a home about 13 miles southwest of Harrison just after 5:30 PM. One resident was treated and released at a local hospital for injuries suffered from flying debris.

The other two tornadoes surveyed were in Laramie county. The first, near Carpenter, was rated as EF-1 with estimated peak winds of 86-110 miles per hour, traveling about 5 miles on the ground in 16 minutes with a maximum width of 200 yards.

Another short-lived tornado southwest of Pine Bluffs was also rated EF-1, with estimated winds of 86 to 110 miles per hour, it was on the ground for
less than ten minutes, travelling about a mile with a maximum width of 80 yards.
