Heavy snow is expected to move in again along the Cascades and the Coast Range on Wednesday night, according to the National Weather Service.
A winter storm warning goes into effect in the north Oregon Cascades and the Hood River Valley at 4 p.m. Wednesday and lasts through 6 a.m. Friday. Forecasters say up to 11 inches of snow could fall as low as 1,500 feet. At 2,500 feet and above, up to 24 inches could accumulate by Friday.
Along the northern Oregon Coast Range, a winter weather advisory begins at 10 p.m. Wednesday, with up to 14 inches of snow possible at higher elevations over the next couple of nights.
Travel will likely be difficult along the coast and mountain passes through at least Friday. Another round of snow could move in Friday night through Sunday as well, reaching lower elevations.
“Snow levels stay down, generally in the 800 to 1,500 foot range,” according to the NWS forecast discussion. “If downdrafts in the showers are strong enough ... could even see some snowflakes survive down to the valley floor, but little if any accumulation would be expected.”
The Portland metro area forecast shows a return to typical, showery and cool March weather starting early next week.
