Avalanche Forecast

With the wet avalanche cycle from the early part of the week finished, focus has shifted to the amount and reactivity of snow that accumulated in the alpine through the midweek. Wind slabs formed with this new snow are our only real avalanche concerns over the near term.

A variable 5-25 cm of wind-redistributed recent snow can be found in the alpine in the region, with amounts tapering rapidly at treeline.

New snow that hasn't already blown away overlies a crust that is becoming thicker and more supportive by the day. In most places this crust is on the surface, gradually forming a frozen lid over the the rain-soaked upper 30-60 cm of the snowpack.

The mid and lower snowpack consists of variable layers of crusts and faceted snow, all diminishing in relevance as the surface crust strengthens.

Overall the snowpack remains unusually shallow.

Saturday night

Decreasing cloud. Northeast alpine winds, 5 - 15 km/h, increasing.

Sunday

Mainly cloudy with isolated flurries. Northeast alpine wind 5 - 15 km/h. Treeline temperature -5 °C with freezing level around 900 m.

Monday

Cloudy with isolated flurries. Less than 5 cm accumulating over the past 3 days. East or northeast alpine winds 10 - 15 km/h, easing. Treeline temperature -4 °C with freezing level around 1000 m.

Tuesday

Mainly sunny. Southwest alpine winds 5 - 15 km/h. Treeline temperature -3 °C with freezing level around 1200 m.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Wind slabs may be poorly bonded to the underlying crust.
• Be alert to conditions that change with aspect and elevation.
• Make observations and assess conditions continually as you travel.
