Sunshine and lollipops... almost!

Use caution transitioning into wind affected terrain, as newly formed slabs may require more time to bond to old layers.

Confidence

Moderate

Avalanche Summary

A few very small (<sz 1) loose dry avalanches were observed today.

Friday, a few natural avalanches up to sz 3 were observed from steep, wind exposed alpine terrain within the hwy corridor. On Thursday, a natural avalanche cycle was observed up to sz 2.5.

Snowpack Summary

Copious amounts of new snow fell last week with mod-strong SW winds. This storm snow has settled to ~40-60cm deep and sits on a reactive layer of stellars (large new snow particles).

The mid snowpack is generally strong, however the deep persistent weakness of rounding facets and a decomposing crust remains.

Weather Summary

A stagnant weather pattern is forecast for the next few days as Arctic air dries outs the atmosphere.

Sun: Mix of sun & cloud, light SE winds, Alp high -13*C, freezing level 400m

Mon: Mix of sun & cloud, light SE winds, Alp high -13*C, freezing level 900m

Tues: Sunny with cloudy periods, trace of precip. Light SW winds, alp high -10*C

Terrain and Travel Advice

Continue to make conservative terrain choices while the storm snow settles and stabilizes.
Start with conservative lines and watch for clues of instability.
Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.

Avalanche Problems

Storm Slabs

Last week's snow fell with moderate to strong SW winds, increasing the potential for large avalanches especially in wind exposed areas. Practice good travel habits and minimize your exposure while these slabs bond.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2.5
