Kernpunkte

Your chances of triggering a wet avalanche will increase as rain intensifies through the day. Heavy, dense snow will accumulate on the uppermost peaks around Snoqualmie Pass. If the snow underfoot starts to feel slushy and wet, or you sink more than a few inches deep, consider moving to terrain below 35 degrees.

    As the rain picks up, expect wet avalanche activity to increase alongside it. If the surface snow loses strength, it will likely fail on the nearest firm layer about six inches down. That should keep most avalanches on the smaller side, but still large enough to push you into consequential terrain like a creek or dense trees. Rain may also knock loose any lingering snow hanging in rocks and cliffs, so don’t linger beneath steep, craggy features.

    Let the snow under your feet guide your decisions. Pay attention to how supportable it feels as you travel. If you’re punching deep into wet, squishy snow, it’s probably time to step back from steep slopes.

Avalanche Discussion

Friday was another warm and sunny day in Snoqualmie Pass. Ridgeline wind shifted southwest, while Pass level wind persisted from the east. Valley inversions lifted, allowing for lower and middle elevations to warm a bit more than previous days. And finally, the low stratus pushed easterly, exiting much of the Crest.

Unsettled weather has returned to the region, but unfortunately, this first round will bring mostly rain to the Pass. You'll have to climb well into the upper elevations to find fresh snow on Saturday. For the lower and middle elevations, expect steady rain starting mid-morning.

The snowpack is in pretty rough shape out there. The last couple nights of radiative refreeze slowed the daytime warming, but overall, there's a net loss in snow coverage. Northerly aspects have had minimal softening in the last couple of days, with southerly aspects offering the best travel. As of now, the upper snow consists of various large grain meltforms on top of a thick, supportable crust layer. It's not exactly clear how the impending rain will impact the already saturated, beaten-up snowpack. Nevertheless, when rain falls on snow, there's also a chance of wet avalanche activity.
