Scattered thunderstorms trained northward near the Florida east-central coast, within a strong southerly flow due in part to the presence of Tropical Depression Five remnants near the central Gulf coast. Around mid day, a waterspout developed over the intracoastal river and moved onshore the mainland in Edgewater, producing minor damage. Several hours later, another storm developed rotation and produced a brief touchdown in a wooded area, farther inland over southern Volusia County.

A waterspout developed over the intracoastal waterway and moved onshore and inland for a short distance before dissipating as the circulation approached US Highway 1. The waterspout developed in association with an isolated, heavy shower that peaked in intensity near the time of the touchdown. The waterspout moved onshore the mainland as a very weak tornado and first impacted Cameron's Marina, where a small boat on a trailer was overturned, damaging an adjacent pickup truck. The weak tornado then continued moving inland on a northwest track, causing soffit damage to another residence and minor tree damage along the remainder of the path. The waterspout/tornado was observed and photographed by many individuals. Interestingly, a condensation funnel was not visible throughout its short life cycle, however, swirling water and debris were apparent and were lifted far aloft. See separate event for waterspout.

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 12:18 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.
