What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

Minor tree damage was noted just north of Harbin Road on Summer Cove Circle. The tornado started producing sporadic tree damage on Pettus Road as it approached the Summerfield Subdivision. It skipped along a path producing major structural damage off of Running Brook Court, removing nearly two thirds of a roof here. Minor roof and siding damage occurred to surrounding homes here as well. It was this damage that was rated EF-1, with wind speeds of 105 mph. Along Sarah Jane Drive, tornadic winds lifted up an awning and caused damage to a home, windows were broken and fences were not only blown over but broken apart and lofted onto and into a house on Jasmine Drive. This house experienced damage from additional debris along with fence segments and posts that impaled the home. Minor damage was noted as the tornado proceeded to move northeast with small branches and shingle damage observed in the Legacy neighborhood. A small outdoor metal shed was damaged and several trees were snapped or uprooted along Douglass Road near Golden Oak Drive before it lifted.
