These included natural avalanches on south aspects that were the direct result of reverse loading. Based on this pattern, we can expect to find reactive wind slabs in unusual locations over the upcoming days.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"f0chs","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"1nhqn","text":"Cold temperatures may have made cornices facetted and weak, highlighting the importance of avoiding overhead hazard and giving them a wide berth when travelling at ridge crest.
