Tornado and Hail in Utah, August 11, 1993

Thunderstorms that developed over the northeast portion of Utah produced a high elevation tornado, large hail, and microburst winds. The tornado occurred in the extreme eastern portion of the county in the Ashley National Forest. The tornado moved from southwest to northeast, touched down three times, and the path width was up to a half mile. The tornado damaged around 1,000 acres of trees. Most of the trees were uprooted, but some up to 18 inches in diameter were snapped. Twenty acres was damaged in the first touchdown, around 600 acres in the second, and near 400 acres in the third. The damage pattern of the trees in the area of the second touchdown confirmed the presence of a tornado. Trees on the north side of the path were thrown south, and the ones on the south side were thrown north. A troop of 125 scouts was camped near the area of the third touchdown. No one was injured, but four vehicles were damaged by the uprooted trees. This accounted for all of the damage. The camp also experienced the 1.00-inch-diameter hail at this time. The highest elevation the damage was found at was 10,800 feet.

Thunderstorms over extreme southern Idaho and extreme northern Utah produced strong microburst winds. The automated weather observing station at Brigham City reported a single gust to 58 mph. Shortly thereafter, the winds quickly subsided.
