Winter storm bears down on Oregon, SW Washington

PORTLAND, Ore. (AP) - Light snow began falling before the morning commute in the Portland metropolitan area, a preview of the heavier precipitation that's expected during the drive home from work and into the evening.

The National Weather Service says a winter storm warning is in effect from the Portland metro area north into Southwest Washington, with potential snow accumulations of 3 to 8 inches.

Snow is also projected to fall in Salem, Corvallis and other parts of Oregon, with the weather service warning that the Interstate 5 passes between Roseburg and Grants Pass could be treacherous.

Those who must drive are advised to slow down, carry tire chains and wear warm clothes.

Portland Community College canceled classes Tuesday and some school districts did the same.
