Snowpack Summary
Clear skies and an elevated freezing level are warming the snowpack and allowing for widespread surface hoar growth. The surface snow may become wet and loose during the heat of the day on sun-exposed slopes. Overhanging cornices may also weaken with the heat.Â
The remainder of the snowpack is well-settled. Numerous melt-freeze crusts exist in the snowpack and all reports indicate that overlying layers are bonding well to them.
The snowpack depth varies from around 200 to 250 cm at the peaks of the North Shore mountains (1400 m) and rapidly decreases with elevation to no snow below 1000 m.
Terrain and Travel
- Cornices become weak with daytime heating.
- Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet
