Kernpunkte

Pockets of wind slab, which formed on Thursday and Friday, could be triggered by backcountry travelers in steep, wind loaded terrain at the mid and upper elevations. Evaluate the snow and terrain carefully, and be cautious when entering steep terrain with wind affected snow. At the lower elevations, recent snowfall lies upon mostly bare ground and avalanches are unlikely.

    Snowfall on Thursday was accompanied by strong westerly ridgetop which created dense wind slabs at the mid and upper elevations. Strong northwesterly winds on Friday continued to transport snow from windward to lee ward aspects. These slabs lie upon a variety of old snow surfaces, which include crusts, wind pack and faceted snow. Backcountry travelers venturing into steep, wind loaded terrain above 8,500 feet could trigger these slabs to depths of 6 to 18 inches.

Avalanche Discussion

The high pressure ridge will remain over the area through Monday. Temperatures at the upper elevations have been slowly warming since early yesterday evening. This trend is expected to continue. Overnight lows will drop into the teens at the upper elevations and rise to near 30 degrees during the day. Winds will back towards the west-southwest. The general avalanche hazard is expected to be Moderate above an elevation of 8,500 to 9,000 feet and to be LOW below that elevation. At the upper elevations avalanches up to 18 inches in depth could be human triggered in steep avalanche starting zones and cliff areas.
