As Hurricane Hermine approached a Gulf of Mexico landfall along the Florida Big Bend, a strong outer rainband moved into the central Florida interior from the eastern Gulf. Within the rainband, several shallow mesocyclones become evident on radar across western Orange County and northwest Lake County. Two EF0 tornadoes were confirmed, as well as areas of straight-line wind damage.

Emergency management officials surveyed an area of wind damage in southern, rural Winter Garden and provided observations and photos to the NWS. In addition, several citizens provided valuable data and at least one person reported seeing a funnel cloud to his south shortly before the onset of damage. A path of damage occurred from the northern portion of the Orange County National Golf Center grounds, northward for 1.5 miles, paralleling Highway 429, just to the east. Significant tree was noted along Porter Road, and along both sides of Hamlin Groves Trail. Over 100 trees were damaged along the path (falling in a convergent pattern), including dozens of pine trees which were snapped several feet above the ground and many others which were uprooted. The path continued northward where five newly built homes on Bowman Drive were damaged. A pool screen enclosure and fences were damaged and a few homes experienced soffit, window and air conditioning unit damage from flying debris. Some debris was carried just north of New Independence Parkway, with no significant damage noted farther north. A review of all available data strongly suggested the damage was a result of a short-track, EF-0 tornado, with maximum winds estimated at 80 to 85 mph. DI1, DOD1, UB; DI28, DOD3, EXP; DI28, DOD4, LB.

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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:41 UTC.

5 more were confirmed in the United States that day.

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.
