Original Post: 

Northern Virginia woke up to power outages and scattered tree limbs and debris in roads after a powerful storm hit the area Friday night, killing two people in its wake after a day of record heat.

Khiet Nguyen, 27, of Burke died at about 11 p.m. after a tree hit his 1998 Mercury while he was driving west on Old Keene Mill Drive near Bauer Drive, according to Fairfax County Police. He was pronounced dead at the scene.

A 90-year-old woman died in Springfield when a tree fell on her home as she was lying in bed, according to FCPD. Another occupant of the home called 911 but was unable to reach the victim.

Police, fire and rescue units responded to the home in the 8100 block of Carr Street in Springfield Friday just before 11 p.m. A construction crane and specialized tree removal equipment have been brought to the scene and the operation is ongoing.

The victim’s name will be released when next of kin has been notified.

According to some local meterologists, Friday night's storm may have been a "derecho."

A derecho is "widespread, long-lived wind storm that is associated with a band of rapidly moving showers or thunderstorms. Although a derecho can produce destruction similar to that of tornadoes, the damage typically is directed in one direction along a relatively straight swath. As a result, the term 'straight-line wind damage" sometimes is used to describe derecho damage,'" according to the National Oceanic and Atmospheric Administration (NOAA).

 

As of 7:30 a.m. on Saturday, the number out of power in the Northern Virginia area was about 450,000 according to Dominion Power spokeswoman Le-Ha Anderson, who was on her way back into the office at about 7:45 a.m. Saturday after a long night updating the media.

"If you experience an outage, it is important that you report it. We will not know your power is out unless you tell us," said a Dominion Power alert on its website. "Every call to our hotline allows our system to narrow down the precise location of the outage so that we can quickly and safely get our crews to the right sites. Also report hazardous or emergency situations by phone." 

Call 1-866-366-4357 to report an outage to Dominion. 

"It's way too soon to say when power will be restored," said Anderson, adding she expects it to be "multiple days" before power is fully restored to all homes. "Today we're focusing on assessing the damage."

NOVEC said crews are currently responding to outages caused by the severe storms. "If your power is out please call 1-888-335-0500 to report it. Due to the scope of the damage, restoration times may be longer than anticipated."
