The National Weather Service has issued winter storm warnings and weather advisories for much of high-elevation Oregon.
Deadman's Pass, near Pendleton.
Winter storm warnings are in effect until Tuesday night or early Wednesday in the Blue Mountains, the east slopes of the Cascades, the Ochoco-John Day Highlands, John Day Basin, Wallowa County, the Grande Ronde Valley and northern Oregon Cascades. A National Weather Service warning means that weather conditions are extreme and people should take care to protect themselves and their property.
A winter weather advisory, which is less extreme, is in effect in the Siskyou Mountains and the Cascades in Lane County and southern and south-central Oregon.
A flood advisory was issued earlier in the day for Clackamas and Multnomah counties. It was scheduled to expire at noon.
