Lo esencial

Small avalanches in isolated areas remain possible under low danger ratings.

Continue to verify conditions and use normal caution in avalanche terrain

Problemas de aludes

  • Wind Slabs

    Small, isolated wind slabs may remain triggerable on steep, upper elevation wind-loaded features.

  • Loose Wet

    Sunny, warmer periods can make wet loose avalanches more likely on steep slopes. Use appropriate sluff management techniques and avoid being under cornices or steep sunny features during the warmest parts of the day.

Confidence

Moderate

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

Tuesday’s storm produced some natural avalanches observed by the field team, see photo below. No other recent avalanches have been reported, however observations are very limited this time of year.

Looking ahead, small, isolated wind slabs may remain triggerable on lee alpine slopes. Some wet loose activity may be possible during the warmest parts of the day.

Snowpack Summary

Up to 30 cm of storm snow from earlier in the week has largely bonded with an underlying hard crust. Small, isolated wind slabs may still exist at upper elevations on shady northerly slopes.

Sun-affected slopes have a variable surface crust, which will likely melt and soften with daytime warming, improving the riding quality.

The remaining snowpack has no current layers of concern, having already undergone multiple melt-freeze cycles. Lower elevations may have wet or isothermal snow to ground.

This MIN post describes recent conditions at Mt. Cokely.

Terrain and Travel Advice

  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
