Bad weather may have created a large sinkhole near the intersection of Annandale and Beachtree roads in Annandale, Va.
A severe thunderstorm rumbled through that neighborhood early Friday morning, just after midnight.
Investigators are looking into the possibility that a lightning strike caused the pavement to buckle, damaging some underground Verizon cables.
A manhole and about 20 feet of asphalt also were damaged.
It took almost 12 hours for Verizon crews to make the necessary repairs.
