The Bay Bridge has been closed in both directions while the storm pushes through.
4:33 p.m.: Power outages are becoming a major problem for the entire area, with tens of thousands regionwide in the dark. Follow the latest numbers and find out who to call for help here.

If a tornado warning is issued, take cover in an interior room on the lowest floor of the building you're in.
2:35pm: A Tornado Warning is in effect just south of Fredericksburg, VA for Spotsylvania County in VA until 3pm. A funnel cloud was reported with this storm located 3 miles west-southwest of Fredericksburg and just west of I-95. The warning is in effect until 3pm.
2:06pm: Severe T-Storm Warnings are in effect until 3:15pm for the northern Shenandoah Valley. Storms are headed towards I-81 with possible gusts to 60mph.
Another area of severe storms are just southwest of Frederickburg in VA. These storms are capable of producing large hail and damaging winds.
1:51pm: The next line of storms is approaching the I-81 corridor as it exits the mountains and enters the Shenandoah Valley. Severe T-Storm Warnings are posted for severe winds and large hail. Be sure to keep an eye on Live Doppler Radar as these storms move into the region from the west.
12:28pm: A Severe T-Storm Watch is in effect until 7pm for the majority of the D.C. area. Damaging winds, large hail and an isolated tornado may be possible during the afternoon hours so be sure to stay tuned to the latest severe weather alerts.
12:07pm: Skies are beginning to clear ahead of the next line of storms. This will lead to added instability with additional heating and will help fuel these storms as they pass east of the Appalachian Mountains.
11:54am: A new Severe T-Storm Watch will be issued soon for the D.C. area and points south. In addition, a Moderate Risk for severe storms will also be placed over portions of North Carolina. The Mesoscale Discussion can be found here.

A severe line of storms is moving into WV and is expected to reach the D.C. area later this afternoon between 2pm and 6pm today but may linger even later as they cross the D.C. metro. Models are expecting a line a storms to develop west of D.C. and move east towards the Metro and I-95 corridor south of D.C. Storms may again feature damaging winds and large hail, though a weak tornado may not be out of the question as well.
This system is already developing strong storms over the mountains that I am concerned will continue to intensify once they get east of the Blue Ridge into a more unstable airmass. We'll keep you posted.
9:51am: Storms have weakened as they moved into the D.C. area. It looked as if outflow came through ahead of the storms and took away some of the strength from the line. The Severe Thunderstorm Watch has been cancelled for the majority of the D.C. area besides Calvert and Anne Arundel Counties which will follow shortly.
More storms are developing west of the D.C. area, with the strongest in Ohio and West Virginia. This is the area we will watch for additional development through the early afternoon. Severe storms will continue to be possible through the afternoon hours, and the D.C. area is still under a Moderate Risk for severe weather today.
We are still expecting more storms to fire this afternoon as some clearing is already being noted across parts of the D.C. area. This will help to destabilize the atmosphere, which doesn't need much more destabilization given the already strong dynamics as the area of low pressure and associated shortwave trough approach the reagion from the west.
Numerous showers and storms are expected to affect the D.C. area between 2pm and 6pm and another Severe Watch with Warnings will be possible. The storm activity later today has to potential to be stronger than what the region saw this morning, so don't let your guard down just yet. We will keep you aware of the latest developments through the day so you stay a step ahead of the game.
9:28am: Severe T-Storm Warning in effect for Prince Georges County and Anne Arundel through 10:15am. The majority of this storm is already out of Prince Georges County and the hardest hit areas will be in Anne Arundel from Annapolis and points north. This line will affect the Bay Bridge east to Kent Island and the Delmarva.
9:22am: Storms are rolling through the D.C. Metro currently and will be through the city over the next 30 minutes or so heading into Prince Georges County and Southern MD. Radar Here (Hit Control and F5 at the same time to refresh)
