Survey Summary: The tornado formed in far northern Marion County...
about one-half mile from the Sequatchie County border. It quickly
intensified to a strong EF-2 tornado...with winds of 130 mph as it
crossed into Sequatchie County. A double wide mobile home was
completely destroyed...and an adjacent church roof was heavily
damaged. The tornado passed through a grove of trees...snapping
nearly all of them halfway up the trunk. The strong tornado passed
through a farm and caused significant damage to a two story family
home. Damage indicators suggest the damage to be high end EF-2. As
the tornado continued to track northeast...two additional homes were
heavily damaged before the tornado moved along an unpopulated ridge.
The tornado likely skipped along this ridge as it crossed Hwy 127
and eventually lifted around Window Rock Road.
