In sintesi

Assess for stiff, cohesive slabs on the surface. The recent storm snow may still need time to bond to the underlying layers.

    Moderate to light southerly winds have redistributed 30 to 50 cm of new snow into deep pockets at higher elevations. Where snow remained dry expect to find pockets of storm slabs that are reactive to human-triggering. Be especially cautious transitioning into wind-loaded terrain, more reactive deposits lurk in leeward features.

Avalanche Summary

No recent avalanche activity has been reported.

Please continue to post your observations and photos to the Mountain Information Network.

Snowpack Summary

Variable southerly winds have redistributed 30 to 50 cm of recent snow at higher elevations. Just below the new snow, a layer of moist snow exists at lower elevations, while it has frozen into a thick melt-freeze crust in higher elevations. The mid and lower snowpack is generally well settled and bonding.

Snowpack depths reach 140-180 cm at treeline and higher.

Terrain and Travel Advice

  • Investigate the bond of the recent snow before committing to your line.
