Amos, Allen County
$300K damage
What happened
The National Weather Service conducted a storm damage survey across southeast Allen County to assess damage from the storms on Friday Evening, June 21. There was a significant amount of straight line wind damage across southern Allen County. Most of this damage had wind speeds between 60-65 mph all facing east southeast direction. There were two significant areas of straight line wind damage. There was a barn north of Amos on Highway 99. The second was two large barns just north of Hayesville, TN. ||Interspersed among the straight line wind damage was a tornado which first touched down a half mile east of Amos. A family farm had numerous trees twisted, snapped, and uprooted. Several barns sustained severe structural damage to the roofs. A dozen or so portions of two by fours were impaled into the ground in multiple directions. ||Further southeast on Highland Church Road numerous trees were uprooted and snapped with trees facing from the north northeast to the southeast direction. There was clear evidence that the tornado went to the Tennessee state line in Macon County as we could see trees snapped and uprooted on the state line which correlates well with the NWS Nashville...
