{"blocks":[{"key":"3huoa","text":"An intense storm is taking aim at the region, bringing extreme southwest winds and 40-80 cm of new snow by Saturday afternoon. During the heaviest snowfall midday on Saturday, freezing levels are forecast to rise to 1000 m, creating denser snow over lighter snow and potentially forming a mid-storm crust layer. Freezing levels may reach 1300 m in areas closer to the coast. Extreme southwest wind will likely be a major contributor to the size and likelihood of Saturday's storm slab problem. Even open steep slopes below treeline should be treated as suspect on Saturday.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"c36m3","text":"The new snow is falling on a mix of previous snow surfaces, including harder, wind-packed surfaces, a melt-freeze crust that may have formed on steep south-facing slopes during Thursday's sunny skies, or cold soft snow in sheltered areas.
