After four days of inclement weather blasted the local area with snow, wind, freezing rain and ice, frigid conditions are finally beginning to thaw.
According to the National Weather Service, Camas and Washougal received approximately 9 inches of snow during the past four days, and freezing rain arrived in force on Saturday night and continued into early Sunday morning, creating treacherous road conditions.
Steve Pierce of Northwest Weather Consultants said the recent storm follows a five-year trend.
“There is a trend for several winters with almost no snow, then a big snowfall, then no snow for a few more winters. Rinse and repeat every five or so years,” he said. “This past week was a classic example of nearly the perfect snowfall setup for Portland/Vancouver and the Willamette Valley.
“Cold arctic air swept down from Canada, followed by several Pacific storms sliding over the top of cold air,” he continued. “Cold air is heavy, dense and extremely hard to displace as long as the center of these storms continued to stay south of Portland, as they did. This allowed cold easterly low level winds to blow from the east, transporting additional cold and dry air into Northwest Oregon and Southwest Washington.”
Even on Monday, the National Weather Service continued to warn residents of potential safety hazards including slick roads and falling tree limbs.
