Oregon Weather: Portland Rain, Snow Advisory for Cascades
(Detroit, Oregon) – The National Weather Service (NWS) has issued a winter weather advisory for the south Washington and north Oregon Cascade mountains and for the Cascade foothills. The Portland office of the NWS said the advisory is in effect from 6 a.m. to 5 p.m. on Wednesday for the Cascade foothills, but for the mountains it is in effect from 6 a.m. on Wednesday to 5 a.m. on Thursday.
Meanwhile, Portland is done with snow, but rain will continue with some winds. The Oregon coast will receive yet another windstorm Tuesday night through Wednesday morning, and the coast range is also under a winter weather advisory.
Snow will develop on Wednesday and continue through into Thursday for the mountains. Snow levels will dip below 1,000 feet for northern part of central Oregon before rising back up to 2,000 feet later on Wednesday and Thursday. An accumulation of two to four inches of snow is expected for that area, creating hazardous and icy driving conditions.
For the Cascade mountains of Oregon, snow accumulation will likely reach four to eight inches, while the southern Washington Cascades can expect five to 10 inches of new snow.
“A winter weather advisory for snow means that periods of snow will cause primarily travel difficulties,” the NWS said in a bulletin. “Be prepared for snow covered roads and limited visibilities, and use caution while driving.”
For the Portland metro area, Wednesday will see more rain and highs near 46, with wind gusts as high as 20 mph. Rainfall may reach a tenth of an inch to a quarter of an inch.
On Thursday, the forecast is similar, though with lesser winds (around 13 mph) and more rain – as much as half an inch.
