Avalanche Forecast

On Saturday, several natural loose dry avalanches, up to size 1, were reported at treeline and above. A skier accidental size 1.5 storm slab avalanche was reported on a steep, north aspect at 1500 m.

15-30 cm of recent snow and light to moderate southerly winds have formed small wind slabs on lee features at upper elevations.

These slabs overlie hard crusts on all sunny aspects and mixture of decomposing dry snow and possible small surface hoar in isolated locations on shady aspects.

The mid and lower snowpack is generally well settled and strong.

At the bottom of the snowpack, a layer of weak facets remains present and continues to be monitored for signs of reactivity.

Sunday Night

Scattered clouds clear through the night. Light southeast ridgetop wind. Temperatures at treeline reach a low of -8 C. Freezing levels drop to valley bottom.

Monday

Mainly sunny with a few convective clouds bringing isolated localized flurries, trace accumulation. Moderate east ridgetop wind. Temperatures at treeline reach a high of -3 C. Freezing level 1500 m.

Tuesday

Sunny. Strong east ridgetop wind. Temperatures at treeline reach a high of -2 C. Freezing level 1600 m.

Wednesday

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Be carefull around freshly wind loaded features.
• Avoid exposure to slopes that have cornices overhead.
• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
