County officials compared the dangerous conditions Arlington will experience over the next 24 hours to the heavy winds of the June 29 derecho, which lasted 24 minutes.
Already some power problems and falling trees and power lines have been reported. Dominion reported 423 customers without power in Arlington earlier this afternoon, but power has since been restored to most. Firefighters are currently on the scene of a large tree that fell on to a house on the 2900 block of N. Oxford Street, in the Bellevue Forest neighborhood. The house was unoccupied at the time and nobody was hurt.
