Regions: Kananaskis.

Daytime heating and timing are the key to success in the spring.  Good trip planning means setting realistic objectives and alpine starts to get ahead of the heat before the snowpack destabilizes.

Weather Forecast

Cloudy with sunny periods.  Light precipitation amounts.  Alpine temperature at 4.0 C for Monday.  Winds will be westerly light moderate.  Freeze levels 2700 meters.

Avalanche Summary

Yesterday in the Rockies saw a mix of wet slabs, loose wet and cornice failures up to size 2.5 with daytime heating and direct solar radiation.

Snowpack Summary

Last night the temperatures dropped and some light precipitation fell as dry snow.  The snowpack is in typical spring shape with conditions ranging from frozen crusts with light dusting over top to moist and wet surfaces by early to mid morning.  The name of the game is to get up early, pay attention to temperatures and complete your objectives well before things fall apart.

Avalanche Problems

Deep Persistent Slabs

Increased caution in shallow snowpack areas with daytime heating.
Travel early on frozen crusts before the heat of the day.>Be aware of the potential for full depth avalanches due to deeply buried weak layers.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 3 - 6

Cornices

Cornice activity will increase with stressors of any daytime warming and/or solar inputs.
Cornices become weak with daytime heating. >Do not travel on slopes that are exposed to cornices overhead.>

Aspects: North, North East, East, South East, South, South West.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 2 - 5
