Lo esencial

Monday will be another warm, sunny day in Snoqualmie Pass. Wet avalanches are possible on any aspect, along with snow shedding from above off rocks and cliffs. If the snow starts to feel mushy underfoot, or you find yourself sinking deep into the wet snow, shift to lower-angle slopes or more supportable snow.

    Wet loose avalanche activity will continue on Monday, despite slight cooling and changing cloud cover. Temperatures around the Pass haven’t dropped below freezing since April 3, and while there might be a better overnight refreeze, any surface crust will quickly soften with daytime warming. At this time of year, it doesn’t take long for surface snow to destabilize and turn easy to trigger. Fortunately, any avalanche will be confined to the upper part of the snowpack, above the burly 3/25 crust.

    In general, these avalanches are trending a bit harder to trigger, but as the warm weather continues for another day, the problem isn't gone. Snow shedding off rocks and cliffs is also possible as temperatures climb.

    Wet snow will first start to show in the warmest areas, generally the places receiving more sun, but as the day warms, even shaded, northerly areas could turn wet and sticky. Pay close attention to the snow under your feet. As it becomes soft, wet, and less supportable, move to lower-angle terrain or areas with more supportable snow.

Avalanche Discussion

Sunday turned the heat up a notch compared to the previous days. Around Alpental, temperatures at 5000' reached 50 degrees F by midafternoon. Sunny skies continued with some light cloud cover passing through. East wind kept the Pass slightly cooler than the surrounding zones. A light surface crust was present early, but the snow turned soft by late morning. Observers near Snow Lake reported active shedding off cliffs and rocks, along with small natural wet loose avalanches in rocky terrain and couloirs.

Conditions on Monday will look similar, with a slightly better overnight refreeze and some light cloud cover. A shift to westerly winds may bring warmer air into the valleys and lower elevations, along with an increase in ridgeline wind speeds.

We’re in the first week of April, and the longer days, higher sun angle, and warm temperatures are showing their teeth. This is a good time to evaluate travel plans and anticipate the avalanche danger. If you're headed into the backcountry, start early while the snow surface is still firm and supportable. As the day warms, move away from large, steep slopes to lower-angle terrain, or consider ending your day before peak heating. Keep a healthy distance from cornices, as the warmth continues to weaken them.
