An F0 tornado first touched down in southwest Mobile county about 8 miles southwest of the Mobile Regional Airport. The initial touchdown was near Jeff Hamilton Road, just to the east of Newman Road. The weak tornado moved across open fields and forest, moving across Newman Road near the Branson subdivision. The tornado then moved through the subdivision, blowing down several trees. Some homes were damaged as a result of the fallen trees, while other homes suffered roof damage due to the high winds. The tornado then moved north and crossed Airport Boulevard just west of Newman Road. More trees were blown down here, and several more homes suffered damage, mainly to roofs, from either fallen trees or high winds. The tornado then lifted back into the cloud, about 5 miles southwest of the Mobile Airport. The line of thunderstorms that produced the tornado was associated with the remnants of Tropical Storm Allison, which were moving east across the region.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

32 minutes of warning. NWS MOB issued a tornado warning for this county at 12:08 UTC, 32 minutes before the tornado touched down, in force until 12:45 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 05:57 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
