Several reports of skier triggered wind slabs in last day. Exercise caution as you transition into open terrain at tree-line and above.
Wind slabs that exist from redistribution of recent storm snow still exist in the alpine and some tree line locations. The wind slabs are sitting on a variety of surfaces including hard slabs, SH and facets.
Recent storm snow has been redistributed by winds to create widespread wind effect, wind slabs and scoured surfaces in alpine a tree-line elevations. The Jan 30th surface hoar/sun crust layer is variable in distribution, is 40-75 cm down and is producing hard sudden planar results in snowpack tests.
Report of a skier triggered size 1.5 wind slab near Yoho Pass in the alpine. Another report of a skier triggered avalanche (size 1.5) near Vermillion Crossing at treeline. Sunshine skil hill reported several size 1 wind slabs in the alpine. Very little recent natural activity observed.
Cold weather will continue on Wednesday and then a warming trend begins on Thursday. For Wednesday valley bottom temps rising to -10 during the day and ridge-top temps rising to -15. Winds will be light from the north-west. Little to no snow forecast through end of week.
