Last night, around 5:30 pm, a tornado hit Northeast Portland, uprooting trees and pulling bricks out of chimneys and shingles off roofs.
It is the second tornado to hit the metro area in nine months but only the fifth tornado in Portland history.
Experts suggest caution before drawing any link between global climate catastrophe and this element of freakish local weather.
Matthew Cullen, a meteorologist at the National Weather Service Portland, says that "looking at the impact of what a changing climate might do [to weather patterns] there is not a strong link with tornadoes."

North Portland was last hit with a tornado on October 28, 2018. That storm was "brief, short-lived," snapping a few tree trunks and overturning an 18-wheeler, says Cullen.
There been five recorded tornadoes in Portland since 1900. The strongest, rated EF-3, was in April, 1972. It started in Portland crossed over into Vancouver.
"People should be aware that there are many weather hazards in the Northwest," Cullen says. "There's of course the potential for a big earthquake and tsunami. Tornadoes are just one more possible threat to be aware of."
