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.

Summary

Weather Forecast

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

An icon showing Loose Wet

A diurnal cycle is developing on steep solar slopes treeline and below, with the most reactivity seen at lower elevations.

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

Aspects: South East, South, South West, West.
