Several supercell thunderstorms moved through southeast Mississippi on the afternoon of May 18th resulting in three brief tornadoes.

This weak tornado touched just north of Pinola along Robert Bush Road, where a tornado debris signature was observed. A few limbs were downed and one tree uprooted. The tornado continued northwest before crossing Jupiter Road. Here two trees were downed, with one on each side of the circulation and facing opposite directions. Large limbs were downed as well. The tornado crossed into a wooded area. The tornado likely continued in the wooded area but no accessible roads were available. Maximum estimated winds were 80 miles per hour.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 19:54 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.
