The best skiing and riding will be at and below treeline in sheltered locations. Be cognizant of large avalanches having the potential to run full path.
Weather Forecast
A mix of sun and cloud this morning, giving way to flurries this afternoon with accumulations of 2-4cm. Freezing levels should remain at valley bottom, with light to moderate winds out of the south. Tomorrow we're forecasted to receive another 15cm and 11cm for Thursday, with gradually rising freezing levels and strong winds.
Snowpack Summary
Over the last 2 weeks, we've seen consistent snowfalls totaling 135cm at TL with significant winds. Another 14cm fell last night with relatively cooler temps and lighter winds. Expect wind slabs and wind effect in the Alpine and exposed areas at TL. The Dec 15 layer is now buried over 1m, Jan 4th is down ~65cm and the Jan 16th is down ~50cm.
Avalanche Summary
Yesterday's artillery control produced avalanches to size 3.5 and naturals to size 3, running full path to valley bottom out of steep extreme terrain. We're expecting natural activity to taper off today, but it will be still possible for isolated large natural avalanches to fail. Human triggered avalanches are probable on specific terrain features.
Confidence
Due to the number of field observations
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
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.
