South Coast Inland

Avalanche hazard is low, though a widespread surface crust may soften at times.

Keep overhead hazards in mind, reduce exposure to slopes threatened by cornices.

Moderate

• We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

On Thursday, several small size 1 to 1.5 explosive triggered slab avalanches were reported in the Duffey Lake area. These occurred in shallow, rocky terrain features.

Daytime warming and solar inputs may heat up rocks initiating wet loose avalanches in steep terrain.

In the alpine, strong winds have stripped windward terrain and snow is wind affected in lee terrain features. Below 2000 m a crust has formed over a saturated upper snowpack, that may break down on steep, solar aspects during the day.

An older crust with properties that are aspect and elevation dependent is down roughly 40 cm and combined with facets.

The mid to lower snowpack is generally well settled and strong. Snowpack depth ranges from 150 to 250 cm at treeline elevations.

Cornices are reported to be large and looming. Be mindful of them overhead and when travelling on ridge tops.

Thursday Night
Clear skies. 40 km/h south ridgetop wind. Treeline temperature 5 °C. Freezing level 3100 m.

Friday
Sunny. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2400 m.

Saturday
Mostly cloudy. 4 to 5 cm of snow at treeline. 70 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1800 m.

Sunday
Mix of sun and clouds. 1 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C.

• 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.
• Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
