Snowpack Summary
30cm of new snow in 48hrs with strong S winds fell on top of the April 7th sun crusts, wind pressed surfaces and melt freeze crusts at low elevations. The March 18 crust is down 90cm. A very strong dense mid and lower pack sits on up to 50cm of decomposed crusts and large facetted crystals near the ground
Avalanche Summary
Several sz 1 ski cuts and natural avalanches have been reactive on small features on all aspects this week. A sz 2.5 natural was observed from MacDonald Gully 5 on Friday and a new cornice release sz 2.0 was seen this morning from Grizzly path. Glide slabs are still releasing unpredictably, a sz 3 and a sz 4 this week on the S side of Mt Tupper.

Avalanche Problems
Storm Slabs
30cm of recent snow has settled and drifted into a reactive slab on all aspects, up to 50cm deep in places. Solar input today may be enough to trigger this naturally in steep solar features where it sits over a crust
- Use caution in lee areas in the alpine and treeline. Storm snow is forming touchy slabs.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 2.5
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
