Cloud cover is expected to keep temperatures low and solar input at bay. Use extra caution if the sun does come out.
Weather Forecast
Unstable southerly flow brings flurries with 5-10cm of accumulation today. Clouds keeping solar input at bay with freezing levels up to 1700m. Isolated flurries and winds in the light to moderate range tomorrow. A high pressure builds on Tuesday bringing sunny skies, light winds and a substantial warm up with freezing levels reaching over 2500m.
Snowpack Summary
A solid overnight refreeze of the surface crust at 1330m. Moist snow exists below supportive melt freeze crust. Light overnight winds. Several crusts in the top meter of the snowpack provide potential failure layers and sliding surfaces for avalanches. Glide crack slopes continue to open up with spring conditions.
Avalanche Summary
Several moist, loose snow avalanches released during peak daytime warming yesterday. A natural cornice failure triggered a sz 2.5 loose avalanche on a N aspect. Multiple buried crusts can provide a propagation surface for some loose snow avalanches, causing larger than expected slides.
Confidence
Timing of incoming weather systems is uncertain on Tuesday
Problems
Persistent Slabs
Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
