White Christmas thaws, expected to re-freeze

Temperatures head into the mid 20s tonight

KOIN 6 News Staff - PORTLAND, Ore. (KOIN) -- It is very rare when the Portland metro area actually sees a White Christmas, but for a few hours on Monday morning, it happened!

Roads in the metro area thawed to slush mid-day but roads above 500 feet remained icy. Officials cautioned roads and sidewalks will re-freeze Monday night as temperatures dip below freezing again.

Tuesday's commute will be icy and likely treacherous.

Some roads were closed in Multnomah County, and the Portland Bureau of Transportation said they were still working to clear some streets at higher elevations. Most main roads and bridges had been de-iced and are in good shape.

Snow totals

Three inches of snow fell in Scappoose, St. Helens and Salmon Creek, while Mount Tabor saw an inch. At the National Weather Service office in Portland, 7-tenths of an inch was measured by 11 p.m. Sunday. A good portion of Clark County got more than an inch of snow.

 How the storm unfolded

The National Weather Service said the chance of accumulating snow north and east of Portland increased, with the freezing rain/snow line right across the metro. Shortly before 11 a.m. Sunday, they tweeted: "Do not travel unless absolutely necessary..."

Around 12:25 p.m., the NWS tweeted: "Temperatures will stay below freezing, so do not expect much improvement in road conditions for areas north of Wilsonville. Accumulation of freezing rain and snow will begin again by late afternoon as this next round moves in."

Then about 12:30 p.m., NWS tweeted: "While we have your attention, A similar system to this one moves into the area on Tuesday night and Wednesday. More icy weather possible for the PDX metro area."

Whenever freezing rain hits, it affects the MAX trains and buses. At this time, there are no weather-related delays, but it's always a good idea to check the TriMet Service Alerts for the latest details


The Portland Bureau of Transportation is planning for the the possibility of ice or snow. On Wednesday they laid down 7,000 gallons of de-icer around Portland streets. The de-icer works well, unless it rains, like it did on Friday night.

"Rain will wash it away," Rivera said. "If it dries up this weekend, we'll apply it again in advance of the icy conditions expected."

ODOT advised those traveling the central and eastern Columbia Gorge along I-84 to be on the look out for black ice conditions.PDX

It's one of the busiest weeks of the year at airports around the country, including PDX.

About 60,000 people will come and go through PDX each day over the next week or so, with about 1 million travelers in all making their way through PDX this holiday season.

As always it's a good idea to check your flight's status before leaving for the airport, and get there early to help ease the crush of passengers going through security.

Record number of travelers

Between now and January 1, AAA forecasts 107.3 million Americans will travel, either by planes, trains or automoblies. It is predicted to be the busiest travel season on record, and the 9th straight year travel has increased during the holidays.

According to the National Weather Service, Saturday is the best day to do your holiday traveling. While the forecast is still up in the air, NWS predicts ice or snow will affect Cascade passes and the Columbia River Gorge.
