Regions

Waterton Lakes.

New snow and strong winds on Friday night into Saturday will form new slabs. If venturing into avalanche terrain, carefully assess the bond of the new snow to the underlying crust.

Weather Forecast

Friday: Sun and cloud with localized flurries and strong westerly winds. Periods of snow overnight with accumulations of 15-25cm. Alpine high -6.

Saturday: Snow continuing in the morning, then clearing in the evening. Alpine high -5. Light to moderate northeast winds.

Sunday: Cloudy with Sunny periods and isolated flurries. Strong west wind.

Snowpack Summary

Strong west winds have redistributed 5cm of recent snow, and scoured most areas below 2000m down to a thick melt freeze crust. The alpine is highly wind affected, with many windward areas completely stripped of snow and lee areas containing hard wind slabs. The midpack is well settled, though weaker basal facets can be found in thin areas.

Avalanche Summary

No new avalanches observed.

Confidence

Timing of incoming weather systems is uncertain on Saturday

Problems

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.
