The active weather was short-lived but intense in many areas, as thunder crashed and flashes of lightning lit the dark clouds. Wind gusted to 30-40 mph in many spots, with stronger gusts likely in southeastern Pierce County as the squall moved through there.
In its aftermath, roughly 22,300 Puget Sound Energy customers were without power across nearly 300 locations, including Poulsbo, Fall City, Sumner, Auburn, Renton, Maple Valley and Issaquah. Another 5,700 Peninsula Light customers were also without power for a while.
In Silverdale, a woman got a rude awakening when a tree crashed into her home in the 1300 block of Lakeridge Circle Drive. Officials said the woman was napping when there was a loud crash and a tree fell into her bedroom, pinning her legs to the bed.
Luckily, she had her cell phone within arm's reach and was able to call 911 herself. She was taken to a Bremerton hospital for treatment of a leg injury.
In Auburn, a woman was trapped inside her car for hours when a large tree ripped down power lines onto 20 cars at Green River Community College.
"It zapped the hood of my car so it just killed everything," Debbi Hunter told KOMO News by cell phone as she sat inside the car awaiting power officials to tell her it was safe to exit. "And then when I realized the car was dead, I was like 'Oh great!' I just put $1,200 in the car."
Hunter was freed 2 1/2 hours later once her safety was assured and she was not hurt. Classes at the college were canceled due to lack of electricity.
Another tree toppled into a home in Edgewood at the 12700 block of 53rd Street Court East, according to East Pierce Fire & Rescue. The impact knocked out windows and one branch pierced through a wall.
Dina Snider said they spotted cracks inside the home but were thankful no one was home during the storm.
"We've lived here for 70 years and never had a tree fall," she said.
In Port Orchard, a witness reports a tree fell into a shed while a person and their dog were, trapping them briefly. They were OK.
Even the trees that managed to miss any structures caused problems. A large tree fell across the southbound lanes of I-5 near NE 145th Street in Shoreline during the height of the evening commute, but luckily no one was struck. Further north, trees fell across the northbound lanes near Stanwood but were quickly cleared.
Other damage reported in the wake of the storm:
Branches were ripped from trees in Bonney Lake, and there were reports of intense lightning and strong winds.
Trees also were reported down in central and northern Kitsap County. Power was knocked out in parts of Silverdale and most of Poulsbo, including Poulsbo Middle School.
In Seattle, wires were reported down earlier in the 3000 block of Spring Street, according to the Seattle Fire Department.
Suquamish Way was closed at SR 305 to protect drivers from the hazard presented by a tree burning in live power lines there, according to Central Kitsap Fire and Rescue.
Storms were expected to die down Monday night after the sun set and the air mass restabilized.
