MCCALLA, Ala. (WHNT) - The National Weather Service in Birmingham surveyed two tornado paths in central Alabama following Tuesday night's round of storms.

The first tornado occurred in far southwestern Jefferson County, near the intersection of I-59/20 and I-459. This tornado has been rated EF-2 and packed max winds of between 120 and 125 miles per hour.

The tornado touched down near McAdory High School just before 5:45 p.m. Tuesday. The tornado strengthened as it moved toward the Bent Brook neighborhood, where six homes were destroyed and six others sustained significant damage.

Debris was detected on radar not long after the intense rotation developed. The product shown below, known as correlation coefficient (CC), shows how similar or dissimilar objects are in the atmosphere. The lower values (blues) indicate where many objects of different shapes and sizes-- in this case debris-- are located. Since we know a tornado is a rapidly rotating column of rising air, it is picking up debris and lifting it into the atmosphere.
