 Here's Bob Imler in the WTOP Traffic Center. Interlude Beltway heavy and slow from the Dulles Toll Road just before the American Legion Bridge to crash along the right side of the roadway. Northbound BW Parkway, whatever was in the road is out of the road, but a bit slow from Riverdale up to the Beltway. Heavy showers around the region. Be careful out there.
