As Irene moves north toward the D.C., its center has moved offshore, but it is delivering winds of 45 mph at National Airport and ocean surges of 4 feet at the mouth of the Chesapeake, according to weather services.
The worst of the storm is slated between 8 p.m. and 2 a.m. Two incidents reported near Falls Church, a tree down in the westbound lane of Route 50 at Washington Blvd. in Arlington, and an intersection closed by police at Annandale Rd. at Graham Rd.
