The transition to Spring continues. As we enter another storm cycle, continue to monitor snow amounts and winds as this will change drastically day by day.
Summary
Confidence
Avalanche Summary
Field observations from the Ghost are limited so please post what you are seeing on the MIN
Snowpack Summary
Snow below treeline and even in to treeline has mostly disappeared with the exception of in gully's and canyons (Ice climbing terrain) In the early hours this will be frozen and provide easy travel and safer avalanche conditions, as the day warms or the sun's input on the slopes the snowpack will deteriorate condition's quickly
For the week of April 29th we are just about to head into another sizable spring snowstorm. Keep this is mind and consider terrain above your head as the day goes on.
Weather Summary
Occasional convective flurries will surely bring periods of snow to the region as the transition to Spring continues. Otherwise steadily increasing temps and a steadily decreasing snowpack can be expected.
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.
- Be carefull around freshly wind loaded features.
Problems
Wind Slabs
Wind slabs 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
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.
