TornadoTornados are rare but not unheard of in Utah (about two per year are reported). Recently a tornado slammed into Manti in central Utah. The twister tore roofs off houses, downed power lines, uprooted trees and left a trail of destruction a block wide and about ten blocks long. A larger tornado struck Salt Lake City in 1999. That tornado tore through downtown and caused more than $150 million in damage.
