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 brief tornado touched down northwest of Rockford near Kings Bridge Rd causing minor timber damage. Satellite imagery depicted a swath of heavier vegetation/timber damage between Kings Bridge Rd and County Road 47 to suggest low-end EF1 intensity of 90 mph. The tornado continued northeast causing additional timber damage near County Road 47 and US Highway 231, dissipating shortly thereafter.

The wider storm

A surface low positioned over Lake Michigan moved an associated cold front through Central Alabama during the evening of April 2. While a widespread severe weather outbreak unfolded to the north, Alabama saw more concentrated areas of severe weather across northern and central counties in the state. After 10 PM CDT April 2, a small mesoscale convective vortex developed within a broken line of thunderstorms, spawning four tornadoes and areas of wind damage across northern Dallas, southern Chilton, and central and eastern Coosa counties. Three of the tornadoes were rated EF1, with damage primarily consisting of trees and sporadic small structures.

Began near Rockford (32.9182, -86.2450).
