An underground electrical transformer that burst into flames in Dupont Circle continues to smolder, and D.C. firefighters have called in the foam unit from National Airport for help.
D.C. fire department spokesman Pete Piringer said an office building near the fire remained evacuated almost two hours after the fire broke out in the 1800 block of Connecticut Avenue. About 125 firefighters were called to the scene.
There was heavy smoke, and Connecticut Avenue was closed to traffic.
Piringer said the fire was likely caused by the morning's strong storm.
Piringer said there have been manholes smoking in several parts of the city. He said the transformer fire is more serious.
