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

A National Weather Service survey found that an EF1 tornado with maximum wind speeds of 110 mph and a maximum path width of 350 yards touched down on the south side of Fort Oglethorpe, near the Chickamauga Battlefield National Park Visitor Center, snapping several trees near the intersection of Post Road and Lafayette Road. The tornado strengthened quickly as it moved northeast and approached the industrial area of Fort Oglethorpe along Battlefield Parkway. Several businesses sustained structural damage, including a metal building structure along Howard Drive completely losing an exterior wall and part of its roof. It was in this area that a weather station at the Fort Oglethorpe Public Works Department measured a wind gust of 106 MPH. The tornado continued to the northeast, snapping or uprooting trees with a few homes sustaining roof and siding damage from Park Forrest Drive along Cloud Springs Road to Carrol Drive and Karen Drive. The tornado crossed I-75 around Scruggs Road, then crossed the Tennessee-Georgia state line between Scruggs Road and Georgia Highway 41. [04/12/20: Tornado #4, County #1/1, EF-1, Catoosa, 2020:010].
