Regions: Ghost.

Recent snow from upslope storms has increased the avalanche danger in the normally dry region. If you plan on climbing in this area, think about overhead terrain and recent snow. The sun has lots of strength right now so beware that stability will decrease throughout the day as temperature warm up. Share what you are seeing including conditions on the MIN !

Confidence

Low

Avalanche Summary

Loose dry avalanches have been observed from steep rocky faces. Field observations from the Ghost are limited so please post what you are seeing on the MIN

Snowpack Summary

30-50cm of recent low density snow has fallen under the influence of the up slope and convective storms moving through the Ghost region. This snow has seen isolated wind effect, but a few storm/wind slabs were noted in treeline wind affected features failing down 50cm. This new snow is overlying the March Temperature crust that is found on all aspects except high pure north alpine areas. So far, the bond with the new snow and the underlying crust is good. Deeper in the snowpack the February 3rd crust still exists but avalanche activity on this layer has decreased since the warm temps last week have settled out the snowpack. The Ghost region this year has more snow than normal and avalanches should be at the forefront of climbers minds in this region. Steep thin rocky areas will warm up fast under the influence of solar radiation and can trigger deep avalanches

Weather Summary

A mixed bag of weather over the next several days will bring everything from light flurries to sunny skies. Temperatures should be seasonal. Winds will be mainly light to moderate from the SW..

Be aware that when the sun does come out it packs a punch at this time of year and snow stability will quickly deteriorate on the solar aspects. Thin cloud can also lead to a "Greenhouse Effect" that can make the upper snowpack moist and unstable. Lots going on in Spring!

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.
  • Ice climbers should be equipped with avalanche safety gear.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.

Avalanche Problems

Wind Slabs

Variable wind directions will put slabs on all aspects, and primarily in immediate lee areas.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Deep Persistent Slabs

Facets near the base of the snowpack may be trigerred from thin areas. Low probability -high consequence avalanches should be in your mind.

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3
