Update at 11:20 p.m. — The National Weather Service confirms that an EF-0 tornado tracked through Arlington and into the District on Thursday.

Earlier: The storms that whipped through Arlington and the D.C. region yesterday brought power outages and damage, and more trees toppled today, according to the Arlington County Fire Department.

But now the Capital Weather Gang believes the storms caused something else: a rare tornado in Arlington.

As CWG reported, the National Weather Service officially confirmed tornadoes in Herndon and in Southeast D.C. on Thursday. But the CWG team lists several other areas where they believe small tornadoes may have touched down, including in South Arlington near the Pentagon.

Radar indicated rotation there around 1:40 p.m., as noted on Twitter by weather enthusiast Ian Livingston.

Photographic evidence of damage near the Army Navy Country Club is consistent with tornadic activity, according to CWG. That’s also close to where one person was hurt when part of the Macy’s facade and roof at the Pentagon City mall was damaged and fell onto a car yesterday.

The National Weather Service reportedly is assessing damage near the Tidal Basin to determine if a tornado occurred there and along the H Street Corridor; the same storm caused the Arlington circulation. The Capital Weather Gang indicates the possible Arlington tornado may have been a separate occurrence from the one at the Tidal Basin, or that one tornado may have passed over the entire area in question.
