The path drawn at its surveyed width of 300 yards (0.17 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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

The initial touchdown was near the intersection of South Dickerson Pike and Old Dickerson Pike in northeast Davidson county. Trees were snapped, trailers suffered roof and underpinning damage, and an old building had its roof removed.

Damage, which continued to the northeast for over 3.5 miles, consisted of minor roof uplifting along with hundreds of snapped trees. The tornado crossed Rivergate Parkway at the Rivergate Mall. It blew over power poles and business signs. Several large projectiles impacted the Mall's facade, leaving craters as high as 30 feet off the ground. The last evidence of damage was to business signs just east of Rivergate Mall on Gallatin Pike.

Maximum wind speeds in the tornado were estimated to be around 105 mph.

The wider storm

A frontal boundary setup across Western and Middle Tennessee late Friday night (April 30), and remained through the weekend. A persistent southerly flow fed moisture into the area and precipitable water values rose to almost 2 inches, based on data from KOHX upper air soundings. As a series of shortwaves moved through, a band of showers and thunderstorms developed and remained nearly stationary for much of the day on Saturday, May 1st and Sunday, May 2nd, resulting in widespread record flooding across much of Middle Tennessee. Some of these thunderstorms became severe also, resulting in thunderstorm wind damage and seven confirmed tornadoes across Middle Tennessee.

Began near Little Creek (36.2867, -86.7464).
