25 to 35 cm of new snow will accumulate over the course of the day, reaching, at times, a rate of several centimetres per hour. These major new accumulations will be affected by strong to extreme winds, which could create a wide variety of surfaces, ranging from hard slabs to scoured down to the crust in the alpine, and lighter density snow or soft slabs in sheltered areas, or below treeline. This will sit on the few accumulations of the last couple of days, and the January 18th ice formation crust, which is decomposing in some places. In open areas below the treeline, this new snow will overly a thin layer of surface hoar, which was mainly observed on the SW, S, SE, E aspects.

Below the January 18th crust is a generally well settled 15 to 20 cm of snow, resting on the facet from the decomposition of the January 2nd melt freeze crust. This interface sits on a mix of laminated crusts and facets.

• Loose avalanches may start small but they can grow and push you into dangerous terrain.
• Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
• Watch for fresh storm slabs building throughout the day.
• Storm slab size and sensitivity to triggering will likely increase through the day.
