Survey Summary: This small tornado destroyed one outbuilding and 
tore roof panels off another before crossing the state line into the 
Pearidge area of Tennessee just west of Dale Hollow Lake. There was 
actually considerable more tree damage in southwest Cumberland 
County resulting from a prolonged period (15-20 minutes) of 60-70 
mph winds that occurred in conjunction with the storm that produced 
this tornado. A conservative estimate of several hundred healthy 
large trees were uprooted or had their trunks snapped by these winds 
in a 2-mile wide swath over the forested southwest corner of the 
county.  A similar blow down occurred in a 3-mile wide area in and 
near Marrowbone in the northwest part of Cumberland County. 
Cumberland County EMA Director Greg Cary provided for his assistance 
in this survey.
