Avalanche Summary
No new avalanches observed or reported today.
Snowpack Summary
Crusts are found on all aspects below 2400m, and higher on solar aspects. Wind slabs are found in alpine areas along ridgelines and in lee and cross-loaded features. Below treeline has turned into a Spring snowpack with a solid crust when it is cold and moist snow on solar aspects. Be aware of wet loose avalanches on solar aspects later in the day.
An important thing to consider at this time of year is the quality of the freeze overnight. Avalanche danger can change from low in the cool mornings to high in the hot afternoons. The timing of this change is important to monitor so plan you trips with these factors in mind.
Weather Summary
Thursday morning will start off cool at -7c and then the alpine should warm up to +1c. Skies will be a mix of sun and cloud. Solar aspects can feel much warmer this time of year when the sun comes out.
Freezing levels to rise to 2200m.
More details can be found in the Mountain Weather Forecast.
Terrain and Travel Advice
- The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.
- Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
Problems
Wind Slabs
Wind slabs are most likely found in lee features and cross loaded features. You might even find them on all aspects because of the variation of the most recent wind event.
Aspects: All aspects.
Elevations: Alpine.
Likelihood
Expected Size
Deep Persistent Slabs
Facets near the base of the snowpack may be triggered from thin areas and this season there are lots of thin areas. Dont try to outsmart the snowpack and stick to conservative terrain until we get into a good spring diurnal cycle.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
The Feb crust has been the main bed surface for many avalanches this winter. Slopes and features that have not slid should be treated cautiously or just avoided. Dig and look.
Aspects: North, North East, East, West, North West.
Elevations: Alpine, Treeline.
