According to a NOAA National Weather Service damage estimate revised upward yesterday by the local forecaster, a tornado with up to 75 mph. winds damaged Reston homes and trees at about 8:55 p.m. Friday night, April 19 along a four mile, 100 yd. wide, radar-tracked path between Fairfax County and Reston Parkways.
Strong associated inflow winds also downed a 33 in. diameter Red Oak tree in Hickory Cluster ... No. 17 within the 2016 HCA Tree Risk Assessment summary and map ... just northwest of HCA Block 1 Group 5 Goodman Houses. The tree was evaluated by the HCA Consulting Arborist in 2016 to have High combined failure probability and target impact risk ratings due to trunk decay indicated by initial sounding tests, and was pending further arborist testing and recommendations. Fortunately, the tree caused no reported property damage or injuries and did not block Maple Ridge Rd. HCA will remove the downed tree at a future date. Similar winds also downed a large nearby treetop along Fairway Dr. at Hook Rd.
