Recent storm snow may take a bit more time to stabilize.

Summary

Confidence

Moderate

Avalanche Summary

We did not receive any new reports of avalanches on Monday. A few small to large (size 1 to 2) avalanches were triggered over the weekend within the storm snow.

Snowpack Summary

Around 30 to 60 cm of snow since Saturday overlies a hard melt-freeze crust and perhaps isolated surface hoar crystals in wind-sheltered treeline terrain. The snow may be deeper and touchier in wind-exposed lee features.

A weak layer of surface hoar and/or faceted grains buried mid-February is around 50 to 100 cm deep.

The lower snowpack is well-settled.

Weather Summary

Terrain and Travel Advice

Continue to make conservative terrain choices while the storm snow settles and stabilizes.
Be careful as you transition into wind-affected terrain.
Be aware of the potential for large avalanches due to buried weak layers.
Make observations and continually assess conditions as you travel.
Storm slabs in motion may step down to deeper layers resulting in large avalanches.

Problems

Storm Slabs

All the recent snow may take a bit more time to stabilize. This is particularly true where it overlies weak surface hoar crystals and in wind-exposed lee features.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

1.5 - 2.5

Persistent Slabs

It remains possible that riders could trigger surface hoar and/or faceted grains that were buried mid-February, especially at high elevations where a thick crust doesn't exist above it.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

2 - 3
