No new avalanche reports in this region since last weekend. In the neighboring South Coast Inland large wet slabs were reported from southerly aspects up to size 3.5 and ongoing wet loose avalanches have occurred up to size 2. 

Last weekend, multiple large to very large wet slab avalanches were observed near Whistler, size 2-4. Many of these involved the full depth of the snowpack, running to the valley bottom.

As the weather pattern changes and the temperatures drop, I suspect a decrease in natural avalanche activity. However, solar slopes remain suspect when the sun is shining. It can really pack a punch this time of year, even for short periods of time. 

A solid melt-freeze crust exists to the mountain top on solar slopes and up to 2000 m on polar slopes. Above 2000 m on North facing terrain, you may find dry snow and a generally well-settled snowpack. Below treeline elevations, the snowpack has been isothermal but will likely lock up as freezing levels drop. 

Cornices are large and looming along ridgelines. They are weak and very unpredictable. 

Overnight Wednesday: Mostly cloudy. Light northeast wind and freezing levels dropping to the valley bottom. 

Thursday: Mix of sun and cloud. Ridgetop wind light from the northeast. Alpine temperatures near -1 and freezing levels 1500 m. 

Friday: A mix of sun and cloud. Light winds from the East. Alpine temperatures near -2 and freezing levels 1500 m.

Saturday: Snow 10-20 cm. Alpine temperatures near -4 and freezing levels 1400 m. 

On Tuesday, natural wet loose avalanches up to size 1.5 were spotted from steep solar terrain and explosive control work initiated a size 3.5 wet slab from a large South facing avalanche path.

On Monday, wets slabs and glide slabs up to size 3 were reported. Natural wet loose avalanche activity up to size 2 continues with these warm days.

Last weekend, widespread loose wet and cornice activity was still ongoing. The Coquihalla zone also saw glide slabs and wet slabs up to size 3.

A melt-freeze crust exists to the mountain top on solar slopes and up to 2200 m on polar slopes. Above 2200 m on North facing terrain, you may find dry snow and a generally well-settled snowpack. Below treeline elevations, the snowpack has been isothermal but will likely lock up as freezing levels drop. 

Cornices are large and looming along ridgelines. They are weak and very unpredictable. 

Overnight Wednesday: Mostly clear with some upper-level cloud entering the region. Light northwest wind and freezing levels dropping to 600 m. 

Thursday: Mix of sun and cloud. Ridgetop wind light from the northeast. Alpine temperatures near -2 and freezing levels 1700 m. 

Friday: A mix of sun and cloud. Light winds from the East. Alpine temperatures near -2 and freezing levels 1600 m.

Saturday: Snow up to 6 cm. Alpine temperatures near -4 and freezing levels 1600 m. 

No recent avalanche observations have been submitted from this region.

In the neighboring Sea to Sky region and the South Coast Inland, multiple wet slab avalanches were observed over the weekend and as of Monday, size 2-4. Many of these involved the full depth of the snowpack, running to the valley bottom. We suspect similar activity to have occurred in the South Coast region as well.

High overnight freezing levels continue, meaning that the snow surface remains moist or wet. In places where the surface forms a crust overnight, it should quickly soften during the day with sunshine and warm temperatures, but in most places below treeline, I suspect mostly isothermal conditions exist and the snowpack is diminishing quickly. The highest elevation north aspects (above 2200 m) may still hold some dry snow.

Cornices are large and looming along ridgelines. They are weak and very unpredictable.

Overnight Wednesday: Clear with cloudy periods. Light northeast wind. Alpine temperatures +5 and freezing levels 2000 m. 

Thursday: Mix of sun and cloud. Ridgetop wind light from the northeast. Alpine temperatures near +7 and freezing level 1900 m. 

Friday: A mix of sun and cloud. Light winds from the South. Alpine temperatures near -2 and freezing levels 1600 m.

Saturday: Precipitation 10-20 mm. Alpine temperatures near +1 and freezing levels 1200 m.
