List of tornadoes in Washington, D.C.
Wikimedia list article

Although it is a relatively small geographical area and tornadoes are a relatively rare phenomenon in the Mid-Atlantic region, tornadoes are not unknown in Washington, D.C. The District has been hit by at least ten of these damaging storms since modern recordkeeping began in 1950.
The surrounding states of Virginia and Maryland average 10 and 6 tornadoes per year, respectively, which is 0.23 and 0.48 tornadoes per 1,000 square miles (2,600 km2) per year. In the same time period (1953–2004), Washington experienced only two tornadoes. However, this works out to around 0.56 tornadoes per 1,000 square miles (2,600 km2) per year, which is not statistically higher than average for the surrounding area. The climatological peak for tornado occurrences in the area is in July; however, most Washington tornadoes have struck in May, while some have formed as early as April and as late as November.
One tornado of particular historical significance is the 1814 storm. Although there is some debate as to whether this storm was a true tornado, it likely killed some British soldiers, heavy rains helped extinguish the fires set by the British, and the losses suffered contributed to their withdrawal from the city. More recent tornadoes have damaged several national landmarks, including the National Mall, the National Arboretum, the United States Botanic Garden, and the Smithsonian Institution. Another tornado occurred just two weeks after the September 11 attacks in 2001, crossing the National Mall and narrowly missing the Pentagon.
The 1814 storm
On August 25, 1814: A "most tremendous hurricane" struck the city during the Burning of Washington during the War of 1812.
