Avalanche Canada
Rapid loading from rain or snow may trigger natural avalanches to occur. Solar radiation can also be intense and make the snowpack loose and wet and prone to natural avalanches. Think about what you are under. Even a small avalanche can have large consequences in terrain such as gullies that are commonly travelled by ice climbers.

Avalanche Summary
Field observations from the Ghost are limited so please post what you are seeing on the MIN
Snowpack Summary
Recent rain and warm temps have eliminated the snowpack in many valley bottom areas. At treeline and above a winter snowpack remains. The snowpack in this region is generally very thin and solar radiation will weaken it and make it more likely to slide. Rain will also rapidly overload the snowpack and may trigger natural avalanches. Think about the aspect you are on/under and the time of they day you are in these areas. Creeks can also rise quickly on a warm day stranding some climbers behind the rising water.
Weather Summary
The weather is becoming more consistently "Spring" like with warm day time temperatures and cool mornings. Occasional snow storms will cross the region creating elevated hazards at they pass. Other weather elements that will increase the hazard are rain and or intense sun. Many areas at lower elevations have lost there snow cover but treeline and above is still fairly winter like.
More details can be found in the Mountain Weather Forecast.
Terrain and Travel Advice
- The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
Problems
Loose Wet
Watch for wet loose avalanche due to rain or rise in temperatures from the sun.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Deep Persistent Slabs
Facets near the base of the snowpack may be triggered from thin areas. On the solar aspects, full depth avalanches are possible as slopes heat up through the day. Low probability -high consequence avalanches should be in your mind.
Aspects: All aspects.
Elevations: Alpine.
