Avalanche Summary

No recent avalanches have been reported in the region. ExpectÂ thin loose wet avalanches in the alpine and tree line elevation bands in the coming days.

Snowpack Summary

Last weekend's storm delivered 20-30 cm of wet snow in alpine terrain and rain elsewhere. The wet snow has frozen and stabilized the snowpack in all but the highest terrain where isolated storm and or wind slabs may sit above a rain crust. High freezing level and continued precipitation over the coming days will start to break down the recent crust formation.

Problems

Loose Wet

With rain to 1900m expected for Tuesday expect to see loose wet avalanches at all elevations. The expected size of avalanches will increase with elevation; the largest size range being higher in the alpine elevation band.

Watch for terrain traps where small amounts of snow will acumulate into deep deposits.Be alert to conditions that change with elevation.

Aspects: All aspects.

Elevations: Alpine, Treeline.
