Strong thunderstorms produced golf ball sized hail, gusty winds, and a tornado along the Brevard and Treasure Coasts.

A National Weather Service Melbourne damage survey confirms that|a brief EF-0 tornado touched down initially in the River Groves|mobile home community in Micco. The tornado continued to the east-|southeast into the Summit Cove Condominiums complex before|crossing US-1 and emerging into the Indian River Lagoon near the|Sebastian River Marina and Boatyard. The tornado was on the|ground for approximately 0.5 miles, had a maximum width of|approximately 100 yards, and peak winds estimated between 65-75|mph.||Damage was first noted near Love Ct. where the tornado touched|down at approximately 536 pm EDT. Brevard County Emergency|Management conducted an initial assessment and documented between|25-30 structures with at least minor damage in the River Groves|community, primarily along Love Ct., Cherish Dr., and River Groves|Dr. These homes suffered partial damage to carports, awnings,|siding, and skirting. Additionally, several structures lost|portions of their roof when the attached carport or porch awnings|were torn away from the home.||The tornado continued east-southeast toward the Summit Cove|Condominiums complex where some damage was noted to trees near|the clubhouse, as well as siding on nearby homes, on Summit Cove|Dr. The system crossed US-1 before emerging into the Indian River|Lagoon near the Sebastian River Marina & Boatyard, where several|boats were moved from their storage rack. An eyewitness indicates the|tornado briefly became a waterspout before dissipating.||There are no known direct injuries or fatalities as a result of|the tornado.

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 Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:43 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.
