Deep moisture and light east flow led to sea breeze storms developing across the area. One of the storms produced a waterspout over the Tampa Bay that briefly came onshore as a tornado.

A nearly stationary waterspout developed over the waters of Safety Harbor and was pushed onshore near the 400 block of East Shore Drive in Oldsmar. Pinellas County Sheriff's Office found damage to shingles of a home, knocked down branches, a tree, a mailbox, and snapped a guide wire.

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

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

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 19:34 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.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Tampa radar (KTBW), 44 km away, was scanning. The volume nearest the touchdown began at 21:50 UTC.

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.
