Observations Summary
Conditions yesterday remained unchanged. There is a supportive snowpack with a surface crust making for mixed ski conditions. Good turns were found on easterly aspects. Still important to note are the wind slabs in the alpine. These were formed by NW winds, are sitting on a crust and continue to fail in compression tests.
Alpine Conditions
Sub-Alpine Conditions
Mountain environments can be categorised as above or below the tree line, thus Alpine and Subalpine respectively. Find out more about how these types of terrain can create or mitigate backcountry hazards here.
Travel & Terrain advice:
The weather is forecast to change today. Clouds in the afternoon may decrease visibility. Expect good visibility in the morning and possiblty poor visibility in the later afternoon.
The localised ice hazard is a concern particularly on windward slopes where snow has been stripped away. Also, solar aspects will have refrozen overnight so expect them to be icy to start the day. Beware of slide risk on steep slopes.
Field tests are still showing that the most recent wind slabs in the alpine are not bonding well to the previous surface (crust). These wind slabs are predominantly on SE slopes.
Avoid steep convex slopes in the alpine and investigate this interface before committing to steeper lines.
Advisory Confidence: MODERATE - unsure of timing of weather change
We need your eyes too. If you’ve been touring in the Alpine National Park we’d love to know what you have seen. Every little bit helps.
Weather Summary
