Snow at L.L. Stub Stewart State Park in Oregon's Tualatin Valley

Winter Weather Advisory


Winter Weather Advisory

A Winter Storm Watch has been issued for the weekend. Snow is in the forecast the Tualatin Valley and the Portland Region, with accumulation up to several inches possible. However, because weather in northwestern Oregon can be unpredictable, there is no guarantee that snow will accumulate in the valley.

During inclement, snowy weather, chains or traction devices are required on some roads in Tualatin Valley. See alerts >>>

While temperatures in the Tualatin Valley are usually mild in the winter, occasionally a winter storm may pass through, which makes for hazardous driving conditions. Winter storms may also affect public transportation and business hours.
