Update: Strong Storms Affecting Metro Area

Severe Thunderstorm Watch in Effect until 11 p.m.

10:30 p.m. update: The severe thunderstorm warning for the cell in Fairfax County has been discontinued as the storm has weakened. The storm will still continue tracking on a path through northwest D.C., Montgomery and northwest PG county in the next 45 minutes. From here on out, thunderstorm activity should gradually diminish.

10:00 p.m. update: Another severe storm has developed over Prince William County and will move into Fairfax County (where a warning is now in effect), parts of DC and ultimately in Montgomery and Prince George's county in the next hour. Strong winds are the main threat with this storm.

Correction: The 8:00 p.m. update (below) indicated the Severe Thunderstorm Watch had been allowed to expire; but it was actually extended until 11 p.m. The National Weather Service Forecast Office at Sterling did not indicate the watch was extended on its web site as it has been having significant problems transmitting current and reliable information this evening.

Keep reading for earlier updates or to leave a comment.

8:00 p.m. update: Severe storms (warnings are out) in Prince William and southern Fairfax County are moving northeast and should impact the areas inside the beltway, including the District, in the next hour. These storms may produce large hail, strong winds and heavy rain. The Severe Thunderstorm Watch which had been in effect has been allowed to expire, notwithstanding the ongoing severe weather.
