In sintesi

Snow amounts will have a direct impact on the sensitivity of new windslabs. Weather models indicate anywhere from 10 - 30cm in the next 48 hours.

    New snow is reverse loading on weak surface facets or surface hoar. These new slabs will bond poorly. Last week's slab from M to S winds are still suspect. Big open features and cross-loaded gulleys should be avoided until storm passes.

    Faceted snow on ledges and above ice climbs can be easily triggered and can grow quickly by entraining surrounding snow especially in gulley features.

Weather Forecast

Light snow is expected to continue through the weekend with moderate NE winds and cold temperatures. We could possibly get 15 cm by Monday.

Snowpack Summary

New snow on the way will be reverse loading lee slopes with moderate NE winds. Surface faceting and surface hoar will be buried creating a second weak interface in the upper snowpack. Poor bonding between these layers is expected. This new snow sits on a weak and faceted mid-pack with depth hoar to ground.

Avalanche Summary

No new avalanche observations or reports today.

Confidence

Intensity of incoming weather systems is uncertain
