Highlights

Northwest winds increasing over the next few days. This should warm things up a little and increase the Loose Wet hazard.

    Clear skies and little wind will increase the hazard of Loose Wet avalanches on sunny aspects during the middle of the day. With cloud increasing in the forecast, this could cause a little 'Greenhouse Effect', causing the surface to soften quickly. Rollerballing is the first sign that the surface is softening.

    Be mindful if travelling uphill on steep sunny aspects during the heat of the day.

  • Wind Slabs

    With the Northwest winds forecast to increase, any snow still available to transport could begin to form Wind Slabs on Southeastern aspects and in sheltered areas. These slabs will be very dense and difficult to trigger however be cautious if seeking steep terrain on polar aspects above 1800m.

Current Snowpack Conditions

Snow coverage across the forecast area is super variable. Up to 150cm in some areas down to rime covered rocks. With many snow safety practitioners digging all over their areas and guides doing the same, this winters snowpack is becoming quite complicated. Above 1700m a thick rain crust is found closer to the ground with crystal growth observed both above and below. Although not reactive to skier traffic right now the lower snowpack will require monitoring over the next few weeks.

Mountain Weather

Friday: Cloud increasing with patchy rain, more persistent about the Divide. Northwesterly winds developing during the day. Freezing level 1600m rising to 2000m in the evening.

Saturday: Rain in the afternoon, with snow to 1500m, otherwise isolated showers. Northwest winds rising to gale. Freezing level around 2000m.

Sliding Danger

Wind stripped areas and exposed ridges will be very firm. Ice axe and Crampons are recommended if venturing out.
