The tornado was on the ground for just 2.3 miles, in an area south of Clinton and west of Brandywine, the National Weather Service survey said. At its widest, the tornado was 75 yards across.

Its peak winds were just 40-60 mph, classifying the twister as an EF-0, at the very low end of the 0-5 Enhanced Fujita Scale.

The tornado managed to peel off some flashing and damage a fence. Otherwise, it’s damage was confined to “topping” trees and snapping limbs.

Here’s a pretty good video of the tornado that was posted to YouTube, taken around Waldorf:
