(Updated 6:10 p.m.) A short lived, yet strong, string of storms left patches of destruction and power outages after it whipped through the area this afternoon. Although all parts of the county sustained some damage, the worst reports seem to be coming from South Arlington.

According to Dominion Virginia Power spokesman Chuck Penn, as of 5:45 p.m. there were about 6,500 Arlington customers without electricity. Most of the 33,000 Dominion customers currently without power are in Alexandria. However, Penn noted that “this is a very dynamic, unfolding situation” so numbers are changing almost by the minute.

Crews are out right now determining what is causing outages in each neighborhood and fixing the problems as rapidly as possible. One area hit especially hard is in South Arlington at S. Columbus Street and Chesterfield Road. Penn says multiple power pole cross arms were broken and there are spans of wire down. Dominion crews re-routed the circuit and restored power to a number of customers in the surrounding neighborhoods, but others are still in the dark.

“It’s a rather labor intensive job that our workers are engaged in,” said Penn. “We are very much in the restoration mode right now.”

There are numerous reports of trees down and flooded streets. Motorists are reminded not to attempt driving through standing water, as it may be deeper than it appears. Drivers should also treat any dark traffic lights as a four way stop.

Arlington remains under a Flash Flood Warning until 7:30 p.m. and a Severe Thunderstorm Watch until 9:00 p.m. The Capital Weather Gang predicts storms off and on throughout the evening.

Update at 9:35 a.m. — Departing flights are experiencing a “gate hold” at DCA. Delays of at least 30 minutes should be expected, and could get worse throughout the day.

Update at 8:55 a.m. — There is a ground stop for flights arriving at Reagan National Airport due to the weather. Check with your airline for the status on any outgoing flights.

The National Weather Service has put Arlington and the rest of the metro area under a Severe Thunderstorm Watch until 11:00 a.m. That’s in addition to the Flash Flood watch that went into effect at midnight and will last until 8:00 p.m.

NWS notes several rounds of strong storms could soak the area. That could create trouble due to the level of ground saturation from the heavy rains that caused flooding earlier this week. From NWS:

* SHOWERS AND THUNDERSTORMS WILL LIKELY MOVE ACROSS THE REGION
THIS MORNING AND PRODUCE HEAVY DOWNPOURS. RAINFALL AMOUNTS IN
EXCESS OF 1 INCH ARE POSSIBLE. ANOTHER ROUND OF STORMS MAY BRING

THE PAST WEEK…ONLY AN INCH OF RAINFALL IN AN HOUR COULD
PRODUCE FLASH FLOODING OF STREAMS AND LOW LYING AREAS.

TO FLASH FLOODING. FLASH FLOODING IS A VERY DANGEROUS SITUATION.

YOU SHOULD MONITOR LATER FORECASTS AND BE PREPARED TO TAKE ACTION
SHOULD FLASH FLOOD WARNINGS BE ISSUED.

Although the storms have the potential to bring damaging winds and the word “derecho” is being thrown around, the Capital Weather Gang doesn’t expect it to be as strong as the derecho that struck last year.

The Office of Personnel Management has kept all federal offices open, but employees have the option of unscheduled leave or unscheduled telework.
