The path drawn at its surveyed width of 25 yards (0.01 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A waterspout formed over Spa Creek, passed briefly as an EF0 tornado over the Severn Sailing Association Marina at the northernmost point of Eastport, Maryland, and then proceeded back over the mouth of the Severn River as a waterspout. An individual at the Severn Sailing Association Marina provided a video of a waterspout between Eastport and the U.S. Naval Academy, over Spa Creek. The waterspout moved ashore and over the marina. They documented a few trailered and stored small boats that were blown over by the wind in the parking area. The circulation moved quickly back over water into the mouth of the Severn River where additional social media video showed it as viewed from the Route 450 Bridge. Terminal Doppler Weather Radar TBWI operating nearby in northern Anne Arundel County showed the circulation intensify briefly along this track, moving west to east. It dissipated before reaching land on the other side of the Severn River, and north other damage was reported.
