Beautiful January days

Watch for surface facetting that may chase you down steep features as the cooler temps weaken the surface snow

Weather Forecast

The weather pattern continues

Overnight lows around -16

Daytime highs around -9

Winds will continue to be light to non existent through out the forecast area

A small weather change is expected on Wednesday

Snowpack Summary

Surface faceting continues with cooler temperatures. Previous strong to extreme winds have stripped snow from all exposed terrain creating a lot of hard wind slabs and wind affected snow in open terrain below treeline to the alpine. The midpack is supportive. Decomposing surface hoar is found down 40cm to 80cm in isolated sheltered locations.

Avalanche Summary

Field teams out in the Maligne range (Proposal peak) today reported a faceted snowpack to ground.

Confidence

The weather pattern is stable

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.
