{"blocks":[{"key":"8ffn8","text":"Overnight, warmer temperatures and cloud cover may promote a weaker refreeze on the surface of the snowpack, particularly in the north of the region. A thin breakable crust exists on almost all aspects and elevations, while a thicker more prominent crust can be expected at lower elevations and on south-facing aspects. Warm daytime temperatures and the potential for some solar radiation, mainly in the south of the region, may cause these crusts to break down throughout the day.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"5iofu","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"80oa","text":"Strong westerly winds throughout the week have created extensive wind-effect in open areas in the alpine and treeline.
