In sintesi

A warm wet storm in the kananaskis region right now. Snow at higher elevations and a mix of rain and snow at highway elevations. We have low confidence in the freezing levels. A good time to allow the snowpack to adjust to the change and keep your mindset conservative.

    Thin areas are locations where it is more likely to trigger this weakness.

Confidence

Moderate

  • Uncertainty is due to rapidly fluctuating freezing levels.

Avalanche Summary

A reported Skier accidental size 1 wind slab on easterly aspect below treeline on a steep convex roll.

Limited visibility today, A road patrol down the spray noted about 15cm of new snow South of burstall pass today.

Snowpack Summary

Warm temps are creeping in to the region. Rain in Canmore and just below freezing temps along the spray with continuous precip falling, luckily as snow, but just barely. The snowpack is settling faster than the new snow is accumulating at most weather stations.

Up to 10cm of new snow has fallen in the past 12 hours, This new snow is not bonding well to previous surfaces. This continues to be transported at treeline and above by strong to extreme westerly winds creating windslabs 40-60cm thick in lee features. . As you transition into these areas be looking for these problems. These windslabs are overlying a generally well settled snowpack.

The deep persistent weakness is buried deep in the snowpack down 150-170cm. This layer was active as recently as last week being triggered from a thin shallow snowpack area. Always be curious about snowpack depths and be thinking how the snow has been moved around creating thin areas.

Below 2100m a layer of surface hoar (spotty distribution) is down 40cm and may be a concern as the snowpack settles with the incoming warmer temps.

Weather Summary

Monday pm: Varying forecasts have a snow fall spread of 8cm-25cm. A low temperature of -5. Winds will be strong out of the west

Tuesday: Cloudy with some sunny periods. A day time high of 0° with winds at 40km/h out of the west.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.
