(Updated at 3:45 p.m.) Fairfax County firefighters have descended on a forested residential neighborhood in Annandale in an effort to extinguish a two-alarm brush fire.

About a dozen units were dispatched to the 6900 block of Alpine Drive at 2:47 p.m. for a house fire, according to scanner traffic on OpenMHz.

“First units on scene reported a large volume of fire behind a house,” the Fairfax County Fire and Rescue Department said on Twitter. “Crews working to extinguish the fire.”

Scanner traffic indicates that the fire has been spreading outdoors without reaching any of the homes in the neighborhood, which has the Evergreen House apartments as well as single-family houses.

“Nothing’s spreading to the homes. It’s all in the yard and trees,” a responder said on the radio.

A few trees were burning 30 to 40 feet up in the air, the incident commander said, who advised firefighters to check for dead trees.

The fire department said at 3:38 p.m. that responders had most of the fire under control. No buildings were affected, and no injuries were reported, but the fire covered approximately 2 acres of land.
