Sudden high winds caused damage at a home near Lake Roesiger on Sunday afternoon, but it wasn't immediately known if it was a small tornado.
The wind ripped siding off the home, demolished a playhouse, and blew items, including a trampoline, across the yard.
"It sounded like a jumbo jet landing on the house. It was pretty intense," said the homeowner, Nathan Arneson.
His wife Amanda looked out the sliding glass window and saw what she described as a tornado.
"It wasn't huge, but it wasn't small. It was about the size of our house, but it was moving really quickly," she said.
KING 5 meteorologist Lisa Van Cise said the National Weather Service would be sending someone out Monday to investigate.
"They'll have to go see where the damage was and do an evaluation before they'll tells us A, if it was a tornado and B, what strength that tornado was," she said.
"I have to say with this cool air coming in it is completely possible that that's what could have happened. We just have to have the official word from the Weather Service before we start to throw that word around."
Late last month, the National Weather Service confirmed that an EF0 tornado touched down briefly in Eatonville. It had maximum wind speeds of 75 mph and was on the ground for less than a minute.
Damage included a carport ripped away, a leaning utility pole, and a road sign that was knocked down.
The NWS says Washington averages 2 to 3 tornadoes per year. In 1997, Washington had a record 14 tornadoes.
