(Updated at 2:15 p.m.) For the second day in a row Arlington is under a Flood Watch.
The National Weather Service says that “anomalous moisture coupled with the potential for multiple slow moving thunderstorms will result in the potential for flash flooding.” The storms are expected to arrive later this afternoon, with the Flood Watch set to expire at 8 p.m.
A Flood Watch has been issued for Arlington, as heavy rain and strong storms are possible starting late this afternoon.

Update at 6:20 p.m. — It appears that Arlington has been spared significant damage, at least from the first wave of storms. While rain and lightning are continuing, few power outages have been reported here so far. Fairfax County saw some bigger impacts, however, with Dominion reporting nearly 15,000 customers without power there. Additional storms are possible later tonight and a Tornado Watch remains in effect until 9 p.m.
