Weather officials: Ice storm brings life-threatening road conditions

EUGENE, Ore. -- Most of Oregon's roads are coated with a thick layer of slush and ice, creating what the National Weather Service is calling life-threatening driving conditions through Sunday morning.

Drivers should stay off the roads unless absolutely necessary, officials said.

An ice storm is hitting the South Willamette Valley through Saturday coupled with winter storm warnings from the Coast Range to the Cascades adds to the already dangerous conditions.

Oregon State Police are requiring drivers to use chains on Interstate 5 from milepost 209 (the Harrisburg exit) north to the Washington State border.

Chains are also required at all Cascade Passes and along Highway 22E in the Detroit area.

From National Weather Service:

Moisture will be increasing across the region this morning. With cold air still locked over the interior, expect significant ice and snow accumulations.

Ice accumulations of 0.25 to 0.75 inch are expected to south of Salem, with 4 to 10 inches of snow to the north of Salem. Distance from Salem will determine which precipitation type is more dominant.

Farther south, more it will be just freezing rain, while farther to the north, more that precipitation type will be just snow.
