Snow started coming down Sunday in many parts of Oregon and doesn’t look to be slowing down anytime soon. According to the latest report, there is enough cold air expected to be in place for a snowstorm to hit the heavily populated Interstate 5 corridor of Oregon as well as southwestern Washington.

Many schools are delayed or closed, and a winter weather advisory is in effect for the Portland and Vancouver areas until the early afternoon, as well as the South Willamette Valley in Oregon.

According to the National Weather Service, snow is already sticking to roads in areas above 300 to 500 feet around 5:45 a.m.


The snowstorm so far looks to be the worst between Portland and Eugene, with some areas having an excess of 6 inches. Crossing the Oregon Cascades at this time is said to be pretty much impossible, as an avalanche was reported to have closed U.S. Highway 20 west of Santiam Pass on Monday morning.

KVAL reports as of 5:30 a.m., storm impacts had also closed:

  • Oregon 38 west of Elkton between MP 29-37
  • U.S. 101 south of Bandon at Four Mile (MP 282)

Highway 58 is also said to be closed for 73 miles, going from Pleasant Hill to U.S. Highway 97 in Central Oregon.

The Oregon Coast was not left out either, as Highway 126W is said to be closed from Veneta to Mapleton.
