Avalanche Forecast

Moderate

No new avalanches were reported in the last 24h. Numerous wet loose avalanches (size 1.5 to 2) were naturally triggered by the sun on steep sun-exposed terrain at treeline and alpine throughout the region earlier this week.

If you are going out in the backcountry, please consider filling out a Mountain Information Network (MIN) report.

A weak melt-freeze crust has likely formed at the snow surface with overnight cooling which may soften during the day.

Alpine slopes are wind-affected, scoured, or faceted snow on northerly slopes. At treeline, a widespread layer of large weak surface hoar crystals was observed at the snow surface on sheltered terrain. Steep slopes are still holding moist snow at mid and lower elevations.

The mid and lower snowpack is generally well settled and bonded.

Snow depths at treeline vary across the region. Currently, 100 cm is reported near Whistler and 65 cm near Blowdown Mountain.

Thursday Night

• A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
• Make observations and continually assess conditions as you travel.
