Dvonk,
Avalanche Canada
More snow fell in some locations along the spray road then forecasted originally. The skiing was excellent in sheltered locations today. Watch for fresh and buried wind slabs if you enter more exposed terrain.
Summary
Confidence
Weather Forecast
Sunday is calling for an additional 6-10cm of snow.
Temps are pretty mild (Day time highs of -5)
The wind is calming down to 10km/h out of the SW
Avalanche Summary
A loose dry cycle to Sz 1.5 was observed off all steep unskiable alpine faces today with the storm snow sluffing off. Some of these were running in to ski terrain. Be alert of the overhead you are traveling in. No signs of slab activity today.
Snowpack Summary
Forecasters were in the Black prince area today in the alpine bowls and were happy to find an unexpected 30cm of storm snow! This snow is settling out very fast with the warm temps. A couple pits were dug at TL and found Moderate shears down 35cm and 80cm. These were both on small facets and did not propagate in extended column test. Otherwise the bond to previous layers is improving with the warmth.
Terrain and Travel
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Be alert to conditions that change with elevation and wind exposure.
- Wind slabs may be poorly bonded to the underlying crust.
- Minimize exposure to sun-exposed slopes when the solar radiation is strong.
Problems
Wind Slabs
Continuing snow and warm temps will continue to build wind slabs where exposed to the wind. You can expect to find these on lee and cross loaded features in the Alpine and NW-SE aspects in open tree line.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
Carefully evaluate the bond with the Feb 19th crust down 40 to 60cm. Recent wind loading will make this problem more reactive, as will periods of intense solar input.
Aspects: South East, South, South West, West.
Elevations: Alpine, Treeline.
