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 tornado touched down on County Road 122, snapping and uprooting hard and softwood trees, just east of County Road 91. The tornado continued moving to the east-southeast, snapping and uprooting widespread trees along CR 122. Though there were numerous softwood trees that were damaged, notably, there were several large 4-6 foot in diameter oak trees that were likely 100 years or older that were snapped and uprooted. This led to the slightly higher rating of the tree damage. Any structural damage along this path was from trees that were knocked over by the tornado, and minimal roof loss was noted in this location.

The wider storm

A significant outbreak of tornadoes occurred in two waves during the evening of the 8th and early morning hours of the 9th. The first wave occurred as multiple supercell thunderstorms developed across southern middle Tennessee and far north central Alabama. These storms moved east during the evening hours, producing ## tornadoes in north central and northeast Alabama.

A break in the activity was then followed by a line of thunderstorms that dropped southeast through southern middle Tennessee into north central and northeast Alabama after Midnight through the early morning hours. The line produced tornadoes in southern middle Tennessee, a couple of which continued into northeast Alabama. Additional tornadoes occurred with the line in far northeast Alabama.

In addition, locally heavy rainfall from the slow-moving supercells produced flash flooding during the evening of the 8th, with several roadways covered with or barricaded due to hazardous driving conditions. This primarily affected locations in southeastern Madison County, northern Marshall County, and southwest Jackson County.

Began near Elliot Xrds (34.6050, -85.8120).
