 Traffic and weather on the 8th. Here's Rob Stallworth in the WTOP Traffic Center. New problem northbound on Branch Avenue. Just before the Beltway, a list of reports of an overturned vehicle blocking the left side of the roadway with no response yet on scene. Traveling on Pennsylvania Avenue at Dower House Road, lights are flashing yellow and red, so keep that in mind. Please use caution. Northbound BW Parkway after 197 headed toward 198.
