PHILADELPHIA — Residents in some Philadelphia neighborhoods and surrounding counties were cleaning up widespread damage Sunday caused by a series of short, severe storms that passed through.

The storms, called microbursts, lasted into Saturday afternoon, downing trees and power lines, flooding a handful of streets and causing structural damage. A building that collapsed in a West Philadelphia neighborhood sent bricks into the street, crushing cars and blocking streetcar tracks.

The National Weather Service said at least four of the microbursts brought straight-line wind gusts of 60 to 70 mph (97 to 113 kph) to Montgomery and Philadelphia counties between 2:30 and 3:15 p.m. Saturday. Despite speculation that the damage, including part of a roof ripped off a Philadelphia Housing Authority apartment building, had been caused by a tornado, NWS officials confirmed that straight-line winds were to blame.

The microbursts in Philadelphia are among a series of severe weather conditions across the United States this weekend that included heat waves, flooding and wildfires.

In a news release issued early Sunday by Philadelphia officials, Mayor Cherelle Parker said she had toured the damage in several neighborhoods in her city throughout the afternoon and evening on Saturday. The city issued a Disaster Emergency Declaration related to the storms.

“All levels of government are working together today, tonight and for as long as necessary to respond to this storm, restore services and help our residents recover. That is our commitment,” he said.

Philadelphia Housing Authority officials said 11 residential units were affected by roof and water damage at their apartment building. All residents were safely evacuated to temporary shelter before being relocated to a nearby hotel.

Philadelphia Office of Emergency Management staff also helped evacuate at least one private residential property due to damage, city officials said.
