Avalanche Forecast
Regions: Glacier.
Expect the hazard to rise with daytime warming and solar radiation.
Be prepared with a conservative exit plan if freezing levels rise above forecast.

Snowpack Summary
A surface crust exists on all but northerly aspects, into the alpine. At treeline and above, a settled 30cm of snow sit on the April 7th sun crust and wind pressed surfaces. The March 18 crust is down 90cm. A very strong and dense mid and lower pack sits on up to 50cm of decomposed crusts and large facetted crystals near the ground
Avalanche Summary
A skier accidental size 2.0 occurred in the Forever Young couloir yesterday. A few small wet loose wet avalanches also occurred yesterday from very steep south facing slide paths. A cornice release size 2.0 occurred Sunday morning from the Grizzly path that faces the highway corridor.
Confidence
Timing or intensity of solar radiation is uncertain
Avalanche Problems
Wind Slabs
30cm of recent snow has settled and drifted into a slab, up to 50cm deep in places. The slab has had a few days to settle, but expect there to still be pockets reactive to human triggering in isolated locations near ridge crests.
- Use caution in lee and cross-loaded terrain near ridge crests.
- Watch for shooting cracks or stiffer feeling snow. Avoid areas that appear wind loaded.
Aspects: All aspects.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1 - 2
Loose Wet
Strong solar radiation is forecast for today. Extra caution is required on steep slopes and thin snowpack areas where the sun will have the most affect.
- Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
- Use extra caution on solar slopes or if the snow is moist or wet.
Aspects: South East, South, South West, West.
Elevations: Treeline, Below Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 2
Cornices
Natural cornice failures continue. Avoid exposure to cornices while approaching ridge tops and on ascents from below
- Extra caution needed around cornices with current conditions.
Aspects: North, North East, East, North West.
Elevations: Alpine.
Likelihood: Possible
Expected Size: 1.5 - 3
