DALLAS, Ore. -- A weather microburst took out a barn in Polk County Thursday morning, according to witnesses and the National Weather Service.
A 25-year-old barn was destroyed but no one was injured, according to witnesses. Trees were also snapped and a workshop was knocked over.
Polk County Emergency Management received several calls from people who said they saw what looked like a tornado touching down in the Dallas area around 8:30 a.m. The NWS investigated and said it was most likely a microburst, which is not as powerful as a tornado but can still pack quite a punch.
Weather experts explained that a microburst may look like a tornado, but its winds actually shoot straight down, instead of swirling like a twister. (See diagram at left.) Microbursts have powerful winds which can knock over fully grown trees and pose great dangers to aircraft.

KGW viewer Amanda Soto said she drove through what seemed like "the beginning stages of a tornado" as she headed into Dallas around 8:15 a.m.
"I saw out of my front windshield a huge cluster of leaves about 30 to 40 feet in the air. I wasn't sure what it was at first, looked like it could have been a bunch of birds," she said. "All of a sudden as I came under them, they very quickly and suddenly moved to the left and started to swirl around me."
She said it was powerful enough to move her car around.
