Microbursts Hit Philadelphia Area With 60-70 MPH Winds Causing Damage

Microbursts swept through Philadelphia and surrounding counties on Saturday afternoon, July 11, producing straight-line wind gusts of 60 to 70 mph that downed trees and power lines, flooded streets, and caused structural damage. The National Weather Service confirmed at least four microbursts affected Montgomery and Philadelphia counties between 2:30 p.m. and 3:15 p.m.

A building collapsed in a West Philadelphia neighborhood, scattering bricks into the street, crushing cars, and blocking trolley tracks. Part of the roof was torn off a Philadelphia Housing Authority apartment building. National Weather Service officials stated the damage resulted from straight-line winds rather than a tornado.

The storms formed part of a broader weekend of severe weather across the U.S. that included heatwaves, flooding, and wildfires. Mayor Cherelle Parker toured affected neighborhoods throughout Saturday afternoon and evening.

The city issued a Declaration of Disaster Emergency. Philadelphia Office of Emergency Management staff also evacuated at least one private residential property.

“Every level of government is working together today, tonight, and for as long as it takes to respond to this storm, restore services, and help our residents recover. That is our commitment,” Mayor Cherelle Parker said. Residents in Philadelphia neighborhoods and surrounding counties began cleaning up from the damage on Sunday, July 12.
