A Winter Storm Watch is in effect from late Sunday night through Monday afternoon for the Greater Portland and Vancouver metro area, Central Willamette Valley including Salem, North Oregon Coast and Coast Range.
Heavy snow is possible. Total snow accumulations of 2 to 6 inches possible, with 3 to 8 inches of snow possible near the Coast Range. It is also possible some locations along the coast and in the Willamette Valley may receive accumulations of less than 2 inches.
Most likely period of snow will be Monday morning. Snow is expected to change to rain by Monday evening, though a few pockets of freezing rain will be possible near the Columbia Gorge and in some Coast Range valleys.
Travel could be very difficult. The hazardous conditions could impact the Monday morning commute. Impacts appear less likely for the Monday evening commute at this time. Be sure to carry chains and a winter emergency kit if you must travel Monday, and be prepared for long delays.
A Winter Storm Watch means there is potential for significant snow, sleet or ice accumulations that may impact travel. Continue to monitor the latest forecasts.
