What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 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 damage survey conducted by the NWS Wakefield office found a path of storm damage consistent with an EF1 tornado. The tornado likely developed as a waterspout over the York River, then moved onshore at Middle Peninsula State Park. The tornado then quickly tracked north northwest, crossing over Rosewell Plantation, Gum Point Lane and Taliaferro Lane. Numerous trees were snapped and uprooted in this area consistent with EF1 damage. Some roof materials and siding were also removed from homes in this area. The tornado then briefly moved over the York River again before crossing over Hermitage Lane and Primrose Path where additional snapped trees were observed. The tornado continued to move north northwest before lifting near Cappahosic Road.
