From the Storm Events narratives, unedited.

The tornado first touched down near Stone Road and continued north northwest, intensifying as it reached Jamaica Road and Box Road. This is where the tornado was the strongest, producing extensive tree damage, consistent with high end EF-1 intensity. The tornado continued north past Coleman Dairy Road, producing damage at a mobile home park. The tornado then crossed Lott Road and lifted shortly thereafter.

A best track is the record a warning agency settles on after the storm, not what it said at the time: position, maximum sustained wind and central pressure every six hours, revised against every observation that came in later. Category is the Saffir-Simpson scale, which runs from Category 1 at 64 kt to Category 5 at 137 kt and reads wind only, so it says nothing about surge or rain. Accumulated cyclone energy adds up the square of the wind through the storm's life, so it counts strength and duration together.
