{"blocks":[{"key":"eoa6v","text":"30-60 cm snow that fell earlier in the week has been blown by moderate to strong winds in exposed treeline and above since then.  Much of this wind was west / southwest but variable winds have been reported across the region - including northerly winds.  Winds are forecast to shift to northwest overnight and into Monday.  Wind slabs will likely remain reactive to human triggers, and are the most reactive during periods of moderate to strong winds.  Cornice development may be found along ridgecrests and deep windslabs on lee slopes.

This potential avalanche problem remains on our radar. This layer produced very large and destructive avalanches in shallower snowpacks within one of our nearest neighbours in the recent storm, highlighting the need to remain cautious of it in shallow, rocky alpine snowpacks.  The most likely spot to trigger it would be on thin and rocky slopes or,  like above, from step down avalanches or a cornice collapse.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"fo2dj","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"2ul44","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}}],"entityMap":{"0":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary?q=lee#cornices"}},"1":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary?q=leeward#leeward"}},"2":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary?q=crust#crusts"}},"3":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary?q=persistent+weak+laye#persistent-weak-layer"}},"4":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary?q=facet#facetcrust-layer"}},"5":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary#surface-hoar"}},"6":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/glossary?q=step+down#step-down-avalanche"}}}}
