Avalanche Forecast
Regions: Ghost.
Up to 40cm of recent snow and moderate variable direction winds have created new windslabs in alpine terrain and isolated areas at treeline.
Confidence
Low
Avalanche Summary
Field observations from the Ghost are limited so please post what you are seeing on the MIN
Snowpack Summary
At treeline and above a winter snowpack remains. Recent upslope storms have deposited up to 40cm of new snow in alpine areas that has been redistributed by variable moderate winds. Think about the aspect you are on/under and the time of they day you are in these areas. A cakey, drummy feeling is a good indication of new windslabs forming and being reactive to light loads such as a climber.
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
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.
Avalanche Problems
Wind Slabs
Windslabs in open alpine areas near the tops of some routes. Lots of uncertainty with regards to this problem and how it is bonding to the underlying surface.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 2
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.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2.5
