Regions

Waterton Lakes, Waterton.

Winter Returns!! Snow is expected on Friday through the day followed by a few days of cold temperatures.

There will be good skiing to be had, but uncertainty lies with how well the new snow will bond to the old crust.

Confidence

Low

Avalanche Summary

No new avalanches were observed this week.

Snowpack Summary

Up to 20cm of windslab overlies Mid January Crust and Christmas Crust which both exists to 2400m. Alpine and Treeline midpack is well settled and overlies basal facets and depth hoar especially in thin areas. Below treeline the crusts are consolidated and overlie facests and depth hoar to ground.

Weather Summary

Friday

Overcast with snow all day. Precip amounts 20-30cm. Temps will hover around -5 in the alpine. Moderate N'erly winds.

Saturday

Broken skies with moderate NE winds. Temps will fall to -26 during the day. No significant precip.

Sunday

Broken skies with moderate NE winds. Temps remain near -26 during the day. No significant precip.

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.

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
