Points saillants

Spring conditions exist in most locations. North aspects may still hold the persistent problem, be cautious and inspect. This is the time of year to start early and finish early. Watch for warming and direct solar input when travelling through terrain. Check out Avalanche Canada's blog on Spring Conditions for some good tips.

Problèmes avalancheux

  • Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    2–3.5

    Watch for sheltered northern areas where this layer may still exist. If triggered slabs could step down into the basal layers. Solar aspects could also see full depth releases during times of intense solar radiation and daytime heating.

  • Loose Wet

    • Alpin
    • Limite forestière
    • Sous la limite forestière

    The strong April sun and daytime heating will lead to loose wet avalanches, particularly in steep terrain.

Avalanche Summary

No recent activity observed or reported.

Snowpack Summary

The snowpack is steadily transitioning to a Spring snowpack.

On north aspects in the Alpine, dry snow can still be found, and weaknesses in the lower snowpack could still be triggered, as these areas have not completely morphed into a Spring snowpack. Otherwise all other aspects and elevations consist of multiple layers of crusts and/or a well settled snowpack. These crusts will break down through the day depending on air temperatures and solar radiation. There are still many areas with basal facets/depth hoar that could awaken if the snowpack gets warm enough.

Timing is everything. As surface crusts break down during the day the avalanche hazard will begin to increase. Start early and finish early.

Weather Summary

Wednesday should be a mix of sun and cloud with light winds and no precipitation. Thursday and Friday will be warmer. Freezing levels will steadily increase each day:

Wed - 2200m

Thurs - 2600m

Friday 2800m

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Even brief periods of direct sun could produce natural avalanches.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
