This adds to the existing wind slab problems brought on by powerful east and northeast winds that have been redistributing loose snow into wind slabs.

The images in this MIN from Rainbow show the extensive wind effected snow.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":330,"length":8,"key":0}],"data":{}},{"key":"cmq3e","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"a8il8","text":"Monday's snow adds to the 15 cm of older low density snow that can be found in shaded, sheltered areas and to more widespread wind-affected snow.

On solar aspects, a thin sun crust may be found near the new snow interface or beneath recently wind transported snow. Both of these interface types are contributing to the reactivity of new wind slabs.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"7o6te","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"frisf","text":"Below the evolving surface, 50-100 cm of settled storm snow sits on a persistent weak layer from late January that consists of facets at upper elevations, surface hoar in sheltered areas, a melt-freeze crust below 1900 m, and a sun crust on south-facing slopes.
