{"blocks":[{"key":"dffdd","text":"At upper elevations, 20-40 cm of recent snow has seen some wind affect and is likely undergoing continued transport as winds pick up into Sunday morning. Wind direction has been predominantly westerly but may also have southerly or northerly components, depending on elevation. Rising freezing levels on Sunday may promote settlement and slab development in the previously cold, dry snow at lower elevations. This could result in isolated reactivity where this snow sits over surface hoar.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"8r9mj","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"ln6h","text":"A couple of persistent layers exist 60-80 cm and 80-150 cm below the surface, having formed in mid-February and late January, respectively. These are composed of combinations of surface hoar, crusts and facets. The depth of these layers mean that they require very large loads to trigger, but when triggered they produce large, destructive avalanches. This has been demonstrated this weekend in Kootenay Pass. So while they are currently difficult to trigger in a recreational context under the current conditions, these layers remain on our radar.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"9vluv","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"al6b7","text":"Shallow snowpack areas in the east of the region may harbor a facetted basal snowpack as described in this MIN report.
