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

This supercell tornado developed in southern Rankin County along the Rankin and Simpson County Line. The tornado touched down along Myers Road as a low end EF1 with winds around 90mph. Tree damage was observed with uprooting and snapping occurring in this region. The tornado then crossed Highway 49 and went into the Piney Woods School area, where high end EF0 damage around 70-85mph occurred. Some shingles were damaged to a home and tree damage continued. The tornado began a slight eastward turn before Clara Foote Road and St. Johns Road. The tornado remained similar intensity in this region before turning back northeast and causing minor damage to a shed outbuilding and small branches broken in the Cato area. The tornado lifted around Cato Road. The maximum estimated winds were 90 mph.
