Avalanche Forecast

Issued: Mar 22nd, 2024 1:15PM

The alpine rating is moderate, the treeline rating is moderate, and the below treeline rating is low. Known problems include Wind Slabs and Deep Persistent Slabs.

Recent snow from upslope storms is increasing 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 decrease throughout the day as temperature warm up.




Avalanche Summary

Loose dry avalanches 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 affect from the wind 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 settling 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

Light snow is forecast to continue with accumulations around 5cm. Winds will continue to be light out of the NW and skies will generally be a mix of sun and cloud. Temperatures will be -12C overnight warming up to -8C by midday.

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

Terrain and Travel Advice

  • Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
  • 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.


Wind Slabs

An icon showing Wind Slabs

Variable wind directions will put slabs on all aspects, and primarily in immediate lee areas. These include settlement or storm slabs.

Aspects: All aspects.

Elevations: Alpine, Treeline.



Expected Size

1 - 2

Deep Persistent Slabs

An icon showing 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.


Unlikely - Possible

Expected Size

1.5 - 3
