Avalanche Forecast
Issued: Apr 5th, 2022 4:00PM
The alpine rating is Wind Slabs, Loose Wet and Cornices.
, the treeline rating is , and the below treeline rating is Known problems includeTimothy Johnson,
Strong winds have created fresh wind slabs in the alpine. On Wednesday watch out if the sun comes out - wet loose avalanche down low and cornices up high could wake up.
Summary
Weather Forecast
Wednesday
A mix of sun and cloud.
Precipitation: Nil.
Alpine temperature: High -8 C.
Ridge wind west: 10-25 km/h.
Freezing level: 1400 metres.
Thursday
A mix of sun and cloud.
Precipitation: Nil.
Alpine temperature: Low -8 C, High -3 C.
Ridge wind southwest: 15 km/h.
Freezing level: 2000 metres.
Snowpack Summary
Strong SW winds are redistributing the recent snow into lee features in the alpine and down into treeline. The freezing level is around 2200m. There is a sun crust high into the alpine on solar aspects and and melt freeze crust up to 2200m. There is a well settled mid-pack.
Avalanche Summary
A few small, size 1 wind slabs have been observed in higher elevation leeward features.
Confidence
Problems
Wind Slabs
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.
- Use caution in lee areas. Recent wind loading has created wind slabs.
- Watch for stiffer feeling snow. Avoid areas that appear wind loaded.
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 and solar input.
- Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.
- Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.
Aspects: South East, South, South West, West.
Elevations: Below Treeline.
Likelihood
Expected Size
Cornices
Fresh cornices might become reactive with strong solar input
- Cornices become weak with daytime heating, so travel early on exposed slopes.
Aspects: North, North East, East, North West.
Elevations: Alpine.
