A sequence of microbursts has downed trees, cracked power lines, and damaged buildings across Montgomery and Philadelphia counties. A West Philadelphia building collapsed, sending bricks into the street and blocking trolley tracks. The National Weather Service confirms four microbursts with 60–70 mph winds on Saturday between 2:30 and 3:15 p.m. Officials say the damage is due to straight-line winds, not a tornado, and Philadelphia has declared a Disaster Emergency.
