A slight bump in the alpine danger ratings due to the forecasted snow and winds, inspect the presence of wind effect on your chosen line.

Avalanche Summary

No new avalanches observed or reported today.

Snowpack Summary

Surface wind slabs vary in density from soft (4 finger) slabs at treeline to denser and thicker slabs in the alpine. These slabs vary in depth from 80cm in the alpine to 40cm at 2100m. There was some isolated cracking within these slabs on the Mar 24th crust. Speaking of the Mar24th, it is everywhere, and thick. Today it was found as high as 2450m (our high point) where it was about 5cm thick and very firm. Lower down at 2100m it was down about 40cm and wasn't bonding especially well to the new snow. This will be the layer to watch as spring moves on.

Weather Summary

Sunday evening, Up to 14 cm overnight with a low of -12°c

Monday: A mix of sun and cloud, A day time high of -13 Ridge winds will be 20-30km/h from the Northwest.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

Carefully evaluate steep lines for wind slabs.
Be careful as you transition into wind-affected terrain.
Be alert to conditions that change with elevation and sun exposure.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
