PORTLAND, Ore. (KOIN) — A tornado touched down in Thurston County, Washington Friday afternoon, making an incredible sight for watchful residents.
The tornado formed just before 2 p.m. about 18 miles southwest of Olympia.
KOIN 6 Chief Meteorologist Natasha Stenbock said on Twitter when a tornado doesn’t cause any damage or injuries, it’s described as an EF-U. It hit the ground in an empty field near Old Highway 99 SW, according to the National Weather Service.
It was described as relatively weak. This made it difficult to spot on radar—unlike the more distinct signatures that supercell storms generate. The environment today was only slightly unstable, according to KOIN 6 News’ Natasha Stenbock.
Tornadoes that form in the Pacific Northwest are often weak and brief. Washington and Oregon each see an average of 3 tornadoes a year, based on data collected between 1991-2010.
