| Brief Description: As a new supercell formed in southern Medina County and tracked eastward, it spawned an F2 tornado just west of the small community of Yancey. This was very close to the the site where a devastating F3 killer tornado had struck almost exactly 27 years earlier. This tornado touched down along County Road 731, destroying two homes. It moved toward the northeast for one mile, damaging two other homes and a mobile home while rolling over a car and knocking down several large trees. | |||||||||||
