Tereza Turecka,
Conditions are changing!!!Strong winds, uncertain amounts of precipitation and rising freezing levels should be taken into consideration when heading out.
Summary
Weather Forecast
Saturday: Cloudy with scattered flurries. Accumulation: 4 cm. Alpine temperature: High -4 °C. Ridge wind southwest: 25 km/h gusting to 65 km/h. Freezing level: 1800 metres. Sunday: Snow. Accumulation: 19 cm. Alpine temperature: Low -6 °C, High -4 °C. Ridge wind southwest: 20 km/h gusting to 55 km/h. Freezing level: 1600 metres.
Snowpack Summary
Up to 30cm of new snow with convective flurries and moderate W-SW winds have redistributed the low density, new snow over previous surfaces such as hard windslab and changeable crusts at TL/ALP elevations. The snow pack varies throughout the region from strong supportive snow in deeper areas to weak facetted snow in the shallow areas.
Avalanche Summary
Two large slides occurred on Thursday night in Marmot backcountry, yet a good reminder to beware of low probability, high consequence scenario. Few loose dry avalanches have been observed in the last couple days, mostly off steep alpine terrain and large enough to bury or injure a skier.
Confidence
Problems
Wind Slabs
Recently formed wind slabs can be found in lee features near ridge crests, and in cross-loaded gullies.
- Be careful with wind loaded pockets, especially in steep confined alpine terrain.
- Be alert to conditions that change with elevation.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Dry
Enough new snow has fallen over the past few days to produce Loose Dry avalanches in steep terrain. Use caution in exposed or confined features where small avalanches can have high consequences.
- Be alert to conditions that change with elevation.
- Be careful of loose dry power sluffing in steep, confined or exposed terrain.
Aspects: All aspects.
Elevations: Alpine.
