The damage stretched across West and Southwest Philadelphia, where downed trees, fallen power lines and debris littered neighborhoods.
In the Grays Ferry neighborhood, a large tree crashed onto a Jeep parked along the 1300 block of Grove Street, crushing the vehicle.
"It's just a weird feeling to look outside - no power, no nothing - and then it's just like, bang," said owner Kylif Davis.
Davis said the tree had stood in front of his home for decades.
"Since I was like a kid this tree been here, and this one little 20-minute swoop just swooped it up and slam dunked it on my car," he said.
According to the National Weather Service, at least four microbursts struck Philadelphia during a roughly 30-minute period Saturday, producing destructive straight-line winds that caused widespread damage.
In West Philadelphia, large trees fell inside Malcolm X Park, while another crushed a pickup truck on nearby Pine Street. Carroll Park was also heavily damaged, with numerous trees uprooted, and debris all over the playground.
Philadelphia's Office of Emergency Management said city agencies responded to nearly 300 tree-related emergencies, and the fire department investigated approximately 125 downed wires.
"We've received more than 100 public reports," said Dominick Mireles of the city's Office of Emergency Management.
Mireles emphasized that it's important for residents to report damage to the city so that crews know where to respond, and the city can assess the magnitude of the damage.
The storm also triggered flash flooding. Cars became submerged at the intersection of 58th Street and Lebanon Avenue.
At 58th Street and Lansdowne Avenue, strong winds caused part of a building to collapse. Demolition crews began tearing down the damaged structure Sunday as trolley service in the area remained disrupted.
"It was like bricks flying across the street," said West Philadelphia resident Zahir Warren. "You don't see it, but you can hear them slam into the cars."
Mayor Cherelle Parker declared a disaster emergency and toured damaged neighborhoods Sunday.
"How long is the city's response to recovery efforts going to take? As long as it takes," Parker said.
As cleanup crews worked around the clock to remove debris and restore power, many residents remained without electricity amid rising temperatures.
"I haven't had power in like two days," Davis said. "My animals, the heat, and it's about to be another heat wave."
PECO said approximately 24,000 customers lost power at the height of the storm. By Sunday night, outages had been reduced to about 3,500 customers. The utility said it expects most remaining customers to have service restored by Sunday night or Monday.
