Confidence: High - Stable weather pattern

Main Concerns

Loose Wet - view Avalanche Problems for detailed information.

Travel & Terrain Advice

Daytime solar input will weaken surface layers and fragile cornices. Avoid solar aspects later in the day and give cornices a wide berth above and below. As always, avoid exposure to terrain traps, as even a small avalanche could have large consequences.

Avalanche Summary

No new avalanches observed.

Avalanche Problems

Loose Wet

It will be possible to trigger solar aspects especially at treeline during the heat of the day. Natural avalanches are possible from steep rock faces. These avalanches are likely to be small in size. (Size 1).

Snowpack Summary

Up to 10cm of new snow from last week in the alpine, with lesser amounts below. All aspects below 1500m and solar aspects above have experienced daily melt freeze cycles. Crusts have been breaking down in the late morning or early afternoon. Snowpack below surface layers is well settled. Cornices in exposed ridgetop terrain have continued to grow.
