Several small (size 1-1.5) skier triggered slab avalanches were reported on Sunday. These avalanches were 20-60 cm thick and released on a wide variety of elevations and aspects. The pattern of triggering wind slabs on north and east facing slopes at higher elevations continued. However, there were also a few reports of slab avalanches in sheltered terrain including some small slabs triggered above the rain crust at low elevations in steep gully features, and some small slabs failing on a sun crusts (on southeast treeline slope) and surface hoar (on a west aspect in the trees). Although these avalanches have been small, they highlight the potential to trigger slabs on a wide variety of terrain.

30-60 cm of recent snow is beginning to settle and there is uncertainty about whether it will gain or loose strength in the coming days. There have been a few reports of this snow showing reactivity in isolated sheltered terrain features such as openings at and below treeline (where it sits above small surface hoar or sun crusts) and steep gully features where the snow may be poorly bonded to the early February rain crust. The lower snowpack is generally well settled and strong.

• Start on smaller terrain features and gather information before committing to bigger terrain.
• Be carefull around freshly wind loaded features.
• Minimize exposure to sun-exposed slopes when the solar radiation is strong.
