Avalanche Forecast

High

• Confidence is due to a stable weather pattern with little change expected.

Debris is still visible from large avalanches that ran during the warm wet conditions early last week. In the past 3 days, avalanche activity has been limited to:

• a few cornice falls, some pulling small wind slabs on slopes below, some not

• pinwheeling and small loose wet avalanches out of steep solar aspects at alpine and treeline elevations

This type of activity is becoming less likely with cooling alpine temperatures and repeated melt-freeze cycling on solar aspects.

A widespread crust exists on all aspects, up to at least 2300 m. This crust may soften on steep south-facing slopes during the day. If any shred of dry snow exists on high alpine north aspects, it is almost certainly wind affected. Large, overhanging cornices linger.

The remainder of the snowpack is well consolidated with no concerns at this time.

Saturday Night
Clear skies. 30 km/h northwest ridgetop wind. Treeline temperature 0 °C. Above freezing layer deteriorating, freezing level dropping to valley bottom.

Sunday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1000 m.

Monday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 500 m.

Tuesday
Mostly sunny. 30 km/h northwest ridgetop wind. Treeline temperature -5 °C. Freezing level 400 m.

• Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• Be alert to conditions that change with elevation and sun exposure.
