Slippery conditions returned to the Portland metro area just in time for holiday travel with snow, sleet and freezing rain Sunday.

After wet mix of precipitation through the morning, snow began to fall just before sunset in the city.

As of 5 p.m., the National Weather Service projected 2-3 inches of snow accumulation for the Portland metro area. More was expected in parts of Southwest Washington like Camas and Battle Ground.

NWS expects precipitation to wind down around midnight Sunday, with rain starting around 3 a.m.

“We expect to see all of this precipitation transition into rain, good old-fashioned rain,” said David Bishop, a meteorologist with the NWS in Portland.

NWS, as well as state and local agencies, advise against driving as road conditions worsen.

Crash reports from slick metro area roadways streamed in throughout the day.

What’s called the “precipitation transition zone” set up across the metro area, delivering a mix of snow, sleet and freezing rain from morning into afternoon.

Winter weather advisories and winter storm warnings are also in place for the Columbia River Gorge into Pendleton.

NWS advises travelers check weather and road conditions both where they are and where they’re going.
