More than a foot of snow is forecast at elevations above 2,500 feet, meaning locations like Marion Forks and Government Camp could see white, while travel over the Cascade Range passes could become dangerous.

The forecast calls for as much as 15 inches at pass levels, most likely impacting Highway 20 at Santiam and Tombstone Passes, Highway 58 at Willamette Pass, Mount Hood area and the Highway 62/138/230 area near Diamond Lake and Crater Lake .

“Travel can be very difficult,” NWS wrote in the alert. Winterize your vehicle and have a winter emergency kit on hand if you plan to drive over the Cascade passes. Make sure your emergency kit includes the following items: flashlights, batteries, blankets, a shovel, water, non-perishable food, tire chains, etc.”
