Tropical Storm Fay, and its remnants after landfall, brought high winds, heavy rain, and numerous tornadoes to Central Alabama.

The tornado touched down near the intersection of Needmore Road and County Road 7749. It then moved north-northeastward, roughly parallel to Needmore Road, for about a half mile before lifting. It produced minor damage to the roof of a home, destroyed one outbuilding, damaged the awning of a barn, caused extensive damage to two chicken houses, and snapped off about 15 hardwood trees. This tornado was associated with the remnants of Tropical Storm Fay.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
