Storms swept through the Philadelphia region on Saturday after a dangerously hot and humid day, leaving behind damage, outages, and major disruptions to holiday events and transit. The impact was felt across the area, from Chester County to Center City and South Jersey.
In Chester County, police confirmed a water rescue at the reservoir at Marsh Creek State Park, while other roads were closed because of downed trees and wires. NBC10 Philadelphia reported that the rescue operation was still ongoing just after 10 p.m., and firefighters later said two people were rescued while one person remained missing in the water.
Transit and power outages
The storms also disrupted SEPTA service. The Lansdale/Doylestown Line was suspended because of downed trees and wires, though SEPTA later said service resumed. The Paoli/Thorndale Line remained suspended between Malvern and Thorndale because of mechanical issues and an Amtrak power issue.
SEPTA spokesperson Andrew Busch told NBC10 earlier Saturday, “The tree is south of the Penllyn Station, so we had to suspend service on the Lansdale/Doylestown Line. There is also an Amtrak power issue that has the Paoli/Thorndale Line suspended.”
| Disruption | Impact | Status |
|---|---|---|
| Lansdale/Doylestown Line | Downed trees and wires | Suspended, then resumed |
| Paoli/Thorndale Line | Mechanical issues and Amtrak power issue | Still suspended between Malvern and Thorndale |
Power outages climbed quickly as the storms moved through the region. As of 10:30 p.m., PECO said more than 50,000 customers were without power, before that number fell to around 42,000 just before midnight.
The outages came while PECO workers, including linemen, gas technicians, mechanics, and call center workers, were on strike. In South Jersey, less than 5% of AC Electric customers were without power, according to its tracker.
Concert paused on the Ben Franklin Parkway
The weather also interrupted the “One Philly: Unity Concert for America” on the Ben Franklin Parkway, where concertgoers were asked to leave after the event was paused. NBC10’s Miguel Martinez-Valle was at the scene as the storm forced organizers to stop the show.
Weather threat and regional fallout
The storms followed another very hot and humid day, adding another layer of difficulty for crews, transit agencies, and event organizers. With road closures, rescue operations, and widespread outages unfolding at the same time, the evening became a fast-moving cleanup effort across the Philly region.
Live updates on the concert remained available as conditions changed, while crews continued responding to damage and service interruptions across the area.
