{"blocks":[{"key":"40guj","text":"20-30 cm of new snow with strong to extreme southwest winds on Monday night will mean that fresh storm slabs will be widespread, and likely very reactive on Tuesday. The snow and wind is expected to continue throughout the day on Tuesday, with an additional 10-20 cm expected by the end of the day. This new snow is sitting on a weak layer of surface hoar in many areas.
