Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded
The remnants of Tropical Cyclone Ida traveled across portions of the Deep South on Monday, August 30th, and into Tuesday, August 31st. Bands of tropical downpours and thunderstorms moved northward across Central Alabama on the east of Ida`s circulation. It was in this general area where instability and low-level wind shear values were sufficient for a few rotating thunderstorms. Two EF0 tornadoes were confirmed across the southeast portions of Central Alabama on August 30th. The combination of heavy rain and breezy conditions also downed some trees in several counties on August 31st.
National Weather Service meteorologists surveyed damage in southern Pike County and determined that it was consistent with an EF0 tornado, with maximum winds near 65 mph.||The tornado touched down near White Water Creek Road and traveled northeast while knocking down a few trees and tree limbs. The tornado then turned northward and crossed Highway 231 where video footage of the tornado was taken. The tornado lifted near Parron Church Road.

What this means
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.
