Recent storm snow arrived with significant wind.

Be careful transitioning into wind-affected areas.

Moderate

• We are uncertain due to a highly variable snowpack.
• We are uncertain due to variable freezing levels.

On Tuesday, explosive work produced several size 2 cornice avalanches. We will be keeping a close eye on cornices as the weather warms later this week.

Up to 15 cm of new snow has been redistributed by strong southerly winds into deeper deposits in wind-loaded areas. This new snow overlies a melt-freeze crust on solar aspects and lower elevations, wind-affected surfaces at higher elevations, and facetted snow or patchy surface hoar in sheltered, shaded areas.

A crust from early February can be found down 60 to 120 cm and has shown no recent reactivity.

The remaining snowpack appears to be well settled and bonded.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
• Even brief periods of direct sun could produce natural avalanches.
