Washington Dulles International Airport measured a peak gust of 56 mph as the storms pounded the area. Winds were strong enough to blow the roof off Gonzaga High School in Washington D.C., and these winds may have been from a tornado.

In all, at least twelve tornadoes touched down in three states plus Washington D.C. on April 6.

Wednesday, April 5, Recap

Wednesday, a long-track supercell thunderstorm produced damage from near Ozark, Alabama, to Rentz, Georgia , over a 4.5-hour period.

The supercell first put down a tornado north of Benevolence, Georgia, rated EF2 with winds of 120 mph. This tornado traveled more than 15 miles through Randolph, Stewart and Webster counties. Most of the damage was due to forest land, but one small trailer park was hit destroying one trailer. The tornado continued into southern Webster county.

According to the NWS report on the tornado: "One peanut farm storage building next to the highway was destroyed...fortunately the employees had been sent home at 11am due to the threat for severe weather that day. The owner had left minutes prior as a result of receiving a phone call stating that Weston was in the path of the storm."

The tornado lifted just east of the town of Weston, Georgia.

This supercell continued east-northeastward causing an EF0 in Sumter County, an EF1 in Dooly County north of Cordele, and an EF1 in Dodge County near Gresston.

Finally, the supercell thunderstorm had one more trick up its sleeve. An EF2 tornado was confirmed by the NWS to have traveled more than 20 miles from just south of Rentz to south of Rockledge, Georgia. An autobody repair shop was destroyed south of Rentz, but there were no injuries. In addition, a triangle radio antenna tower was bent over and dozens of trees were snapped.

An anticyclonic tornado, one with winds rotating clockwise as opposed to counterclockwise, was confirmed by an NWS survey team near Eminence, Kentucky, rated EF1 . Anticyclonic tornadoes make up only 1 to 2 percent of all U.S. tornadoes, on average.
