Kernpunkte

Its finally warming!!Keep an eye out on solar S-W aspects as the sun starts to bake them, You will see increased reactivity in point releases.

Lawinenprobleme

  • Loose Dry

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–1.5
    Cold temperatures continue to facet the surface snow causing it to loose cohesion. Point release activity will increase with strong solar input on steep S and W aspects at all elevations.

  • Deep Persistent Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely
    Größe
    1.5–2.5
    The basal weakness (aka depth hoar) is generally dormant; however, these may be possible to trigger in isolated shallow snowpack places.

Weather Forecast

Monday: Sunny, No new precipitation expected. Overnight low: -18 and afternoon high: -10 C. Light E windsTuesday: Sunny with cloudy periods, Low -18 high -9C, Light East ridge windsMountain weather forecast available at Avalanche Canada.

Snowpack Summary

The upper snowpack remains faceted on all aspects. Wind effect in open terrain from previous SW and now N winds. Much of the mid-pack is faceted with some strength and support on skis but not always under foot. Isolated sensitivity to Jan 18th layer at treeline and below, but not consistent to all areas. Large depth hoar on the ground, everywhere.

Avalanche Summary

A road patrol down highway 93S did not reveal much in the way of new avalanches, 1 Size 1 loose dry on steep alpine  NW aspect slope covering recent ski tracks. A bit more wind in the area is adding to the cohesion in the snow pack.

Confidence

Due to the quality of field observations
