An electric transmission company had three metal truss towers collapse about 2.5 miles east of Lowry. The towers were 187 feet tall, with 1700 feet of spacing between each tower.  Using the enhanced Fujita scale, damage indicator 24 (ETL) applies very well; its lower bound for a degree of damage 6 is 116 mph (101 knots).  The towers were rated for 120 mph.  Eight miles to the southeast of the towers, on the southern fringe of the swath, an observer with a home weather station two miles south of Glenwood measured 91 mph before the power went out. The anemometer was mounted ten feet above the top of the house, and was above the tree tops.  Windows were blown in and shingles ripped off.  The roof of an adjacent house was blown away, and numerous trees were toppled or broken.
