Avalanche Forecast

On Sunday, northeast of Stewart, a large (size 2) helicopter triggered avalanche was reported on a wind-loaded northwest facing slope around tree line.

If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network).

By the end of the day on Monday, expect 30-60 cm of soft snow on the surface in sheltered terrain. This covers 30 cm of settling snow that sits on a widespread crust in all but sheltered, north-facing slopes where isolated pockets of surface hoar and/or faceted grains may exist below the recent snow.

Moderate to strong south or southwest winds will likely be forming deeper, more reactive deposits of snow in leeward terrain.

Previously problematic layers deeper in the snowpack appear to have bonded and strengthened, however, there is a small chance that they could remain a risk in steep, north-facing, high alpine terrain.

Sunday Night

Cloudy. 10 to 15 cm of snow expected above 500 m. Moderate to strong southwest ridgetop wind. Treeline low around -6 °C.

Monday

Mostly cloudy. 10 to 20 cm of snow expected above 750 m. Moderate to strong southwest ridgetop wind. Treeline high around -3 °C.

Tuesday

Partly cloudy. 5 to 15 cm of snow expected above 750 m. Moderate to strong southwest ridgetop wind. Treeline high around -3 °C.

Wednesday

Mostly cloudy. Spotty 5-10 cm of snow possible above 1000 m. Moderate to strong south ridgetop wind. Treeline high around -2 °C.

• Make observations and assess conditions continually as you travel.
• Watch for changing conditions today, storm slabs may become increasingly reactive.
• Avoid areas where the snow feels stiff and/or slabby.
• Be careful to keep storm day fever from luring you out into bigger terrain features.
