Event Summary

National Weather Service meteorologists surveyed damage in central Jefferson County and have determined that the damage is consistent with an EF-1 tornado with maximum winds estimated to be 105 mph.

The tornado touched down approximately three-tenths of a mile northeast of Alice Road. The tornado traveled to the northeast where it snapped and uprooted hundreds of trees along the path. It continued nearly parallel to Blue Creek Road and then traveled over private property where it continued to produce damage. The tornado neared Valley Creek and additional trees were snapped or uprooted. It continued on its northeast path and eventually crossed Johns Road where several trees were snapped. The tornado lifted approximately one-tenth of a mile northeast of Sunnyhill Drive.
