Snowpack Summary

Forecasted temperatures, above 0C at higher elevations, means a pause in the spring diurnal cycle and increasingly wet snow on the surface. Polar slopes, which have been less impacted by the sun in the last few days, could offer more of the coarse salt condition that we are looking for in the spring, while polar slopes should slowly move towards soaked, sticky, slow moving snow. (Mashed potato snow). At and below treeline, thawing has been rapid on all slopes. The snowpack is saturated with water and the snow conditions are rather sticky and slow. With no overnight recovery, the snowpack will become progressively more fragile, wetter and cohesive. Melting is fast, and the snowpack varies from 50 cm (valley) to 130 cm (mid-mountain).

Terrain and Travel Advice

  • Be alert to conditions that change with elevation and sun exposure.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Cornices become weak with daytime heating or solar exposure.

Problems

Loose Wet

An icon showing Loose Wet

Warm temperatures and no overnight refreeze could weaken the surface snow and create small wet loose snow avalanches, especially on steep terrain. Keep in mind that wet avalanches can easily push you into undesirable obstacles or terrain traps.

Aspects: All aspects.

Elevations: All elevations.

Likelihood

Unlikely

Expected Size

1 - 2

Cornices

An icon showing Cornices

Spring weather is favorable to cornices falls. Even a small cornice can be destructive and harmful. As they are unpredictable, be sure to stay well away from them at all times.

Aspects: All aspects.

Elevations: Alpine.

Likelihood

Unlikely

Expected Size
