Avalanche Forecast

High

No new avalanches were reported over the weekend and through Monday.

Prior to the weekend there were numerous reports of natural wind slab and cornice-triggered avalanches up to size 2.

Over a week ago, several large deep persistent slab avalanches were reported in the alpine, including a natural size 3 near Kispiox, a cornice-triggered size 2.5 at Hudson Bay and several explosive controlled size 2-3 near Ningunsaw.

Firm, wind affected surface snow in exposed terrain features. Old wind slabs in cross loaded and lee features. Sun crusts on steep, solar aspects. Softer snow in very sheltered terrain features.

Several other crusts, layers of facets, or surface hoar can be found in the top 150 cm of the snowpack, but have not shown any significant avalanche activity or snowpack test results recently.

The lower snowpack consists of weak, basal facets which may become active with any rapid change or shock to the snowpack, such as heavy loading or dramatic warming.

Monday night

Cold and clear as the outflow continues. Wind from the north at 20 km/h. Temperature -20ËšC.

• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Conditions may have improved, but be mindful that deep instabilities are still present.
• Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
