The National Weather Service confirmed that two tornadoes touched down in last Thursday's storms. Neither caused any injuries or deaths.
The first moved from Arlington, Virginia to Washington D.C., starting at around 8:59pm. Winds peaked at around 90 mph, according to the survey estimate. Numerous trees were snapped or damaged, and fencing by the National Mall for Independence Day celebrations was twisted and broken.
The second tornado touched down at 9:08pm Thursday in D.C.; this tornado was separate from the first. The tornado peaked at 80 mph winds, and caused several tree limbs to fall. It dissipated about two minutes later.
