Points saillants

It's exploring season! Whatever tools you use for travel, make sure they're sharp to deal with hard surfaces in the morning. Start and finish early to avoid getting caught in isothermal snow.

    Slushy, isothermal snow conditions may emerge on directly sun-facing slopes during the heat of the day. Plan your route with this in mind to avoid getting surprised by difficult travel and rising wet loose avalanche danger.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

No new avalanches have been reported recently, and under current conditions, very little activity is expected. If you get out into the backcountry, post a MIN!

Snowpack Summary

All of the Island snowpack has now seen temperatures well above 0 °C. Clear overnights will allow surface crusts to form before daytime warming softens the surface again. Even after repeated melt-freeze cycles, travelers appear to still be finding enough boot and ski penetration for effective travel. Sharp footwear may be essential during the morning hours.

Expect surfaces to become moist during the day and even isothermal on sun-facing slopes. Wet loose avalanche danger emerges when this condition is in play, a counterpoint to slip-and-fall hazards when the surface is frozen. Outside of oscillating surface conditions, there are no layers of concern in the snowpack. We still have about 190 cm at 1450 m.
