Regions

Glacier.

The sun is packing a punch!

While hazard starts low in the morning, expect it to increase with solar radiation today.

Manage your exposure to sun exposed slopes accordingly.

Weather Forecast

A ridge of high pressure will bring mainly sunny weather to the southern half of BC today and tomorrow.

Today: a mix of sun and cloud. No precip. Fzl 1500m. Wind W-10km/h

Tonight: mainly cloudy. No precip. Fzl at valley bottom. Wind S-10km/h

Wednesday: mix sun and cloud. No precip. Fzl 1700m. Wind S-10 to 20km/h

Snowpack Summary

A surface crust exists on solar aspects and an otherwise isothermal snowpack at lower below treeline elevations. Settled dry snow is preserved on north aspects in the alpine. The mid and lower portions of the snowpack are generally strong.

Avalanche Summary

Yesterday, several natural wet loose avalanches up to size 3.0 were observed from the steep, south aspect at lower elevations of Mt. Tupper and Cheops. These avalanches started as point releases and gouged to ground in some areas with an isothermal snowpack. A few glide cracks on Mt Tupper have been observed to be on the move.

Confidence

Timing or intensity of solar radiation is uncertain

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
