Moderate

Thursday, small loose wet avalanches were observed on steep south-easterly alpine slopes on Mont Albert. Old evidence of larger loose wet avalanches (up to size 2) was also observed in the same vicinity.

The warm weather, rain, and lack of significant refreeze at night have greatly affected snow conditions on all aspects and at all elevations. Wet snow can be found at the surface (and up to 30 cm deep), making travel conditions rather sticky and slow (mashed potatoes snow), especially at treeline and below. In the alpine, a slight melt-freeze cycle occurred, generating corn snow conditions even on northern slopes. Melting is happening fast and the height of snow varies from 50 cm (valley) to 130 cm (mid-mountain).

• The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
• A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
• Be alert to conditions that change with elevation and sun exposure.
• Cornices become weak with daytime heating or solar exposure.
