1999 Salt Lake City tornado

The 1999 Salt Lake City tornado was a very rare tornado that occurred in Salt Lake City, Utah on August 11, 1999, during an unusually strong summer monsoon season. It was among the most notable tornadoes to hit west of the Great Plains in the 20th century and the second tornado to hit in Utah that resulted in a fatality (the other occurring in 1884). Between 1950 and 2006, this was the sixth significant tornado in Utah since June 1963.
