Thursday morning an EF0 Tornado touched down in Monroe, Washington around 10:30 a.m. in the area of West Main Street and 170th Drive. The area saw minor property damage including the toppling of two RVs, a trampoline thrown in the air, and a smashed car. Luckily no persons were injured.
“It didn’t last long — probably not much longer than a minute,” meteorologist Danny Mercer said. A couple storms like these are typical this time of year, he said. “Flukey spinoffs come off the Puget Sound convergence zone” when winds in the upper atmosphere collide over the region, Haner said. Strong tornados have a “good core” of fierce winds and happen during thunderstorms, Haner said.
