Avalanche Forecast

No new avalanches have been reported.

Looking forward, we expect that human-triggered windslab avalanches will be possible on Monday.

Please consider sharing photos and observations from your day on the Mountain Information Network.

With light snowfall and moderate wind continuing, expect up to 25 cm of soft snow on the surface in sheltered areas, and deeper deposits of wind slab in leeward terrain. Below this, expect to find firm wind-affected surfaces, hard crusts, or loose powder snow (primarily in sheltered north-facing terrain).

Large, fragile cornices can be found on exposed ridgelines and should be given a wide berth.

Below 1300 m the recent snow overlies a widespread melt-freeze crust.

The weather below is for White Pass and Haines Summit. Closer to Carcross, expect less cloud and less snow.

Sunday Night

Cloudy. 5 to 10 cm of snow expected. Moderate south ridgetop wind. Treeline low around -7 °C.

Monday

Mostly cloudy. 2 to 5 cm of snow expected. Moderate south ridgetop wind. Treeline high around -4 °C.

Tuesday

Mostly cloudy. 5 to 10 cm of snow expected in Haines Summit, 2 to 5 in White Pass. Moderate to strong southwest ridgetop wind. Treeline high around -4 °C.

Wednesday

Mostly cloudy. 3 to 8 cm of snow expected. Moderate southeast ridgetop wind. Treeline high around -3 °C.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
