Chinook conditions the next couple of days will result in considerable redistribution of snow and contribute to slab development. If wind values reach forecasted levels we may see an increase to CONSIDERABLE at treeline so watch for wind effects.
Weather Forecast
A strong chinook flow is expected by Tuesday/Wednesday with winds westerly at 65-75km/h gusting to 90-100km/h at times. Temperatures will rise well above seasonal levels and no new precipitation is expected.
Avalanche Summary
Limited minor sluffing in steep rocky terrain. One Size 1 soft slab release triggered by goats on an E aspect at treeline in steep rocky terrain. Ran 75m by 10m wide. Approx depth of 20cm. No tracks or other sign indicating goats were caught!
Snowpack Summary
Storm snow settling slowly. Strong-extreme winds forecast for the day have not manifested themselves in the core of the forecast area but were prevalent only a few km away at the north end of the Spray valley.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
