Tereza Turecka,
While looking for some nice spring turns, aim for above 2000 m and search for sheltered northerly slopes.As the winds are picking up and changing directions, you may be finding wind slabs in more unusual places.
Summary
Weather Forecast
Tuesday: Cloudy with sunny periods and isolated flurries. Precipitation: Trace. Alpine temperature: High -8 °C. Ridge wind west: 25-35 km/h. Freezing level: 1500 metres.
Wednesday: A mix of sun and cloud. Precipitation: Nil. Alpine temperature: Low -15 °C, High -8 °C. Ridge wind west: 20 km/h. Freezing level at valley bottom.
Snowpack Summary
As of Monday morning, up to 15 cm of new snow sits over a sun crust on solar aspects to Mountain top. A Melt Freeze crust exist's on northerly aspects up to 2200m with dry, well settled snow on true north slopes above that elevation. Moderate wind effect in the ALP.
Avalanche Summary
Monday patrol in the Icefields area reported no new natural avalanche activity. A few small, size 1 wind slabs have been observed in higher elevation leeward features.
Confidence
Freezing levels are uncertain
Problems
Wind Slabs
Moderate to Strong SW winds created fresh wind slabs. These new wind slabs sit over a variety of firm surfaces including wind effected snow and sun/temperature crusts. Expect the reactivity to increase as temperatures increase during the day.
- Watch for stiffer feeling snow. Avoid areas that appear wind loaded.
- Use caution in lee areas. Recent wind loading has created wind slabs.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
Main concern during the heat of the day. Watch for light cloud coverage which can promote warming of the surface snow through green house effect.
Aspects: All aspects.
Elevations: Below Treeline.
Likelihood
Expected Size
Loose Dry
Wind sheltered terrain will have 10-15 cm of dry snow sitting over pervious firm surfaces. Expect small, loose dry avalanches in steep sheltered terrain.
- Be careful of loose dry sluffing in steep, confined or exposed terrain.
Aspects: All aspects.
Elevations: Alpine.
