According to a hazardous weather outlook and a winter advisory issued by the National Weather Service, snow showers will bring an additional 1 to 3 inches of snow throughout the day. Additional snow is possible throughout Wednesday and Thursday morning. As of Monday morning, about 11.5 inches of snow had accumulated in the Portland area.

The snowstorm is being referred to as the most severe in Oregon since the January 1969 deluge, in which two to three feet of snow fell in most areas of the state over six days. Hundreds of farm buildings and several large industrial buildings collapsed under the weight of the heavy wet snow, and there were significant losses in livestock, according to the National Weather Advisory. Total Oregon losses from the snowstorm were estimated between $3 million and $4 million.
