Pittsburgh Bureau of Fire and Pittsburgh Police responded to reports of two buildings that had partially collapsed on Butler Street and 48th Street and Butler Street at Plummer in Central Lawrenceville just after 7:30 p.m.
When crews arrived on scene they found the top of one building at 48th Street leaning into Butler Street and a building at Butler and Plummer which had much of its roof ripped off.
Neither structure was occupied at the time and there were no reported injuries. There were large areas of debris scattered on Butler Street.
On the south side of the street in Allegheny Cemetery, several large trees were uprooted.
The National Weather Service confirmed that a microburst touched down in the area. Microbursts are powerful downdrafts that appear suddenly. They're generated by intense cold energy during a rainstorm.
Several streetlights in the area were out and hundreds of Duquesne Light customers were without power in Lawrenceville.
The 4700 and 4800 blocks of Butler Street were closed while PLI inspected the damaged buildings and the Department of Public Works cleared debris from the roadway.
Tonight, the City-County Building is illuminated to recognize Poison Prevention Week and the 50th Anniversary of "Mr. Yuk" in partnership with Children's Hospital of Pittsburgh of UPMC.
For questions about the lighting at the City-County Building, please reach out to the Office of the Mayor.
