With snow levels staying stubbornly low, the Cascades are under a snow advisory and snow is even likely as low as about 900 feet for the second day in a row, according to meteorologists.

Snow fell in the Oregon coast range on Tuesday and in Sandy, Corbett and Hockinson, Wash., among other places, on Monday, said KGW Meteorologist Dave Salesky.

In the Portland area, temperatures were in the high 30s early Tuesday morning.

Meanwhile, the National Weather Service said the snow advisory for the Northern Oregon and Southern Washington Cascades remains in effect until 5 p.m. Tuesday.

Cities affected include Government Camp, Detroit, Santiam Pass and Mount St. Helens.

The Weather Service says to expect from 4 to 8 inches of snow Tuesday. As of 1 a.m. Monday, 2 to 6 inches had already fallen. The higher amounts will be at the ski resort levels.

The snow is the result of showers pushing up against the mountain slopes and will decrease Tuesday night and Wednesday as showers diminish in coverage.

However, more snow is expected to coat the Cascades again later in the week as rain returns to the valley, Salesky said.

Meteorologists urge motorists to be prepared for snow covered roads.
