Conditions have improved but the nature of the snow pack still dictates concern for deeper slab releases. Best practice is to avoid rocky and thin snowpack areas in the alpine.

Terrain and Travel Advice:
    Deep PersistentSlab

    Several persistent weak facet layers exist in the mid-pack and at the bottom of the snowpack. Sporadic avalanche activity continues on these layers and the theme seems to be rocky, steep, thin snowpack areas in the alpine.

    Wind Slab

    Isolated wind-slabs exist in high alpine lee areas. Increased winds forecast for Friday may increase windslab development in the alpine.

    Avalanche Summary

    No avalanches were observed or reported on Monday or Tuesday.

    Snowpack Summary

    Suncrust on steep solar aspects. Isolated wind slabs in the alpine. 10-25 cm of facetted snow over the Feb 3 crust. Persistent weak facet layers remain present in the mid and bottom of the snowpack.

    Weather Summary

    Isolated flurries for Tuesday night and Wednesday with total accumulations less then 3 cm by end of day on Wednesday. Ridgetop winds are forecast to be light to moderate from the west. Freezing Levels will rise to 1800 m on Wednesday.

    For more information be sure to check AvCan's Mountain Weather.

    A deep persistent slab problem remains where the near-surface crust is thin or absent.
    Low-probability, high-consequence problems are best managed with conservative terrain choices.

    Terrain and Travel Advice:
    • Conditions may have improved, but be mindful that deep instabilities are still present.
    • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
    • Recent wind has varied in direction so watch for wind slabs on all aspects.
    Deep PersistentSlab

    A weak layer near the base of the snowpack is a concern where a thick, strong, near-surface crust does not exist. This could be at higher elevations in the alpine and in steep, rocky, open features at treeline,

    Wind Slab

    Wind slabs are slowly bonding, or are getting softer and less reactive due to near-surface faceting. It is still possible for the weight of a human to trigger a small wind slab avalanche.

    Avalanche Summary

    On Monday, natural loose dry avalanches were reported to size 1 in steep polar aspects.

    Over the weekend, several wind slab and loose avalanches were reported, up to size 1.5, in steep alpine terrain, some triggered by humans, and some by the sun.

    Snowpack Summary

    1 to 5 cm of snow overlies wind affected surfaces in open areas and a sun crust on solar slopes.

    In sheltered areas, 10 to 30 cm of settling snow sits over a frozen crust that formed in early February. This crust is generally supportive to the weight of a human below treeline, but becomes breakable around treeline, and disappears as you ascend higher into the alpine.

    The midpack is generally faceted.

    The bottom 15-30 cm of the snowpack consists of weak faceted grains, depth hoar, and crusts that continue to produce sporadic, large avalanches.

    Weather Summary

    Tuesday Night

    Mostly cloudy. 0 to 5 cm of snow. 10 to 25 km/h southwest ridgetop wind. Treeline temperature around -3 °C. Freezing level rising to 1200 m.

    Wednesday

    Partly cloudy. 0 to 2 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature around -2 °C. Freezing level rising to 1700 m. 

    Thursday

    A mix of sun and cloud. 20 to 30 km/h southwest ridgetop wind. Treeline temperature around -1 °C. Freezing level rising to 1700 m.

    Friday

    A mix of sun and cloud. 10 to 25 km/h west ridgetop wind. Treeline temperature around 0°C. Freezing level rising to 1900 m.

    More details can be found in the Mountain Weather Forecast.

    Confidence: moderate
    Uncertainty is due to the fact that deep persistent slabs are particularly difficult to forecast.

    Stick to polar aspects and sheltered terrain to find the best skiing.
    Expect sluffing in steep terrain and watch for exposure to cliffs and terrain traps.

    Terrain and Travel Advice:
    • Loose avalanches may start small but they can grow and push you into dangerous terrain.
    • Be cautious of buried obstacles especially below treeline.
    Dry Loose

    Incoming storm snow will be landing on a very firm sun crust on solar aspects and a variety of surfaces on polar aspects. Steep slopes will try to shed this new snow, which could gather significant mass below and be very problematic in terrain traps.

    Wind Slab

    Recent strong NE winds have created firm wind slabs in the Alpine. Though stubborn to trigger, there may be pockets of slab sitting on weak facets, waiting for the right load to set them free to flow downhill.

    Avalanche Summary

    No new natural avalanches observed along the highway corridor Tuesday.

    On Monday, a few point-release dry sluffs were noted from steep terrain on Tupper and Macdonald.

    In the past week, riders have been triggering unexpected avalanches, near ridgetop in wind effected terrain. These avalanches failed on a prominent crust down ~30-50cm. Terminal Pk & Connaught drainage

    Snowpack Summary

    5-10 cm of new snow freshly covers a spring like conditions. These include: soft snow in protected terrain on polar aspects, breakable crust on steep solar aspects, and variable wind slab in exposed terrain at ridge top.

    A strong, supportive crust (widespread below 2500m) is down 30-50cm, makes for challenging travel and a layer for avalanches to slide on.

    The mid-lower snowpack has strengthened. Isolated pockets of shallow, weak snow can be found in the high alpine.

    Weather Summary

    A weak disturbance this week will bring clouds, light snow, and freezing levels hovering around 1300 m.

    Tonight: Cloudy/flurries, 5 cm, Alp low -5°C, ridgetop winds SW light gusting to Mod.

    Wed: Cloudy/isolated flurries, Alp high -5°C, light SW winds.

    Thurs: Cloudy/isolated flurries, Alp high -6°C, mod W winds.

    Fri: Flurries, 5-10cm, Alp high -6°C, light/gusting mod SW wind.

    Confidence: moderate
