The slight cooling trend is generally favorable, but local verification of conditions remains essential on Sunday.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

One natural cornice fall, size 2, was reported in the alpine high above Crowfoot Glades. No slab was associated with it. Otherwise, no avalanches were observed or reported on Saturday.

Snowpack Summary

Recent warm temperatures have produced crusts or moist snow on solar aspects to treeline and in some steep solar alpine terrain. With a cooling trend underway, these surfaces are likely refreezing. North aspects remain mostly dry and cool. A 10–30 cm slab overlies the Jan 24 interface of surface hoar, crust, and/or previously wind-affected snow.

Widespread previous wind effect in alpine and open exposed areas at treeline.

Weather Summary

Cooling trend through Sunday: valley bottoms hovering near 0 with ridgetops closer to -10. SW winds ease through Sunday into the moderate/light range. A weak precipitation pulse late Sunday/overnight may bring trace to 5 cm (max), but amount/timing is uncertain in the models.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
