Thick-to-thin trigger points and areas where the mid-March crust is not supportive to boots or skis are suspect.Avoid overhead hazards in the afternoon as the sun is starting to pack a punch these days.

Summary

Confidence

Moderate

Avalanche Summary

Small solar triggered sluffs reported by the public on Friday.Maligne area field patrol observed no new natural avalanche activity today .

Snowpack Summary

Thin sun crust present on steep solar slopes at all elevations. Elsewhere, about 10cm of soft snow on top of 2-10cm melt freeze crust on Wednesday. The Feb 3rd crust interface is down 35-60cm. Basal depth hoar makes up the bottom third of the snowpack. HS ranges from 50 to 150cm.

  • Avoid steep slopes when air temperatures are warm, or solar radiation is strong.

Problems

Persistent Slabs

An icon showing Persistent Slabs

Thick to thin trigger points and areas where mid March crust is not supportive to boots or skis are a suspect. This problem layer is the crust and facets created by early February's warm spell. It is down 30-90 cm in the snowpack and is a 1-10 cm thick crust with a layer of weak facets above.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible

Expected Size

2 - 3.5

Deep Persistent Slabs

An icon showing Deep Persistent Slabs

Basal depth hoar makes up the bottom of the snowpack. This is a low probability but high consequence problem. Stay away from weak, rocky, shallow location where triggering this layer is more likely.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1.5 - 3.5
