Snoqualmie Pass

A very thin early season snowpack at Pass level, continues to make accessing middle and upper elevations a huge challenge. However, the snowpack increases dramatically as you ascend. The most likely avalanche issue would be isolated to small wind drifts in very steep, rocky terrain.

The snowpack looks quite impressive for late November, but it’s still early season. Probably two of the most important pieces of information are the numerous (and potentially hazardous) obstacles and the significant change in snow depth as you gain elevation. It’s not surprising that open creeks, downed logs, bushes, trees, and rocks make travel much more tenuous than normal. Give yourself some extra time to deal with these early-season challenges. 

On Friday, any avalanche issues should be limited to very isolated pockets of wind-drifted snow at upper elevations, or maybe a small loose avalanche releasing from rocky terrain. A disturbance passing well to the north could cause winds to increase a bit. Don’t be surprised if you see some blowing snow or fresh drifting. However, these shallow new slabs won’t be much of a hazard unless you’re in very steep and rocky terrain. If you see a firm pillow-like pocket, make sure it won’t carry you over a cliff or into rocks if it knocks you off your feet. 

The snowpack at Pass level is pretty thin (0-12 inches, 0-30cm). However, you’ll find much more snow above 4000 ft (3ft, 90cm) and even more still above 5000 ft (4-5 ft, 120-150cm). Information about the snowpack is still very limited, but our few observations don’t indicate any layers of concern. 

Given the recent weather, you’ll likely find variable snow conditions. Firm and crusty snow is most prevalent at lower elevations and on sunny slopes. Your best chance at finding soft snow will be in more sheltered and shaded terrain.
