Travel and Terrain Advice
Clear skies and sunshine will allow people to push higher and further into the backcountry today. Indications are that the snowpack has begun to settle and gain strength during this warming period however there will be a tipping point as the surface potentially loses cohesion due to solar input at lower elevations. Roller balls in steep terrain starting on southerly aspect will be an indication that this tipping point has been met. At higher elevations in the alpine winds slabs have formed on lee slopes be cautions of steep exposed entries off ridgeline and natural trigger points such as convex rolls.
Avalanche Problem
ウインドスラブ Wind slab
Isolated pockets of wind slab remain at higher elevations around ridgeline. Be wary of open exposed terrain where last week’s wind event has redistributed the lastest new snow onto lee slopes across the east.
点発生湿雪雪崩 Wet Loose snow
Clear skies in the morning and plenty of sunshine will soften the overnight surface freeze with the possibility of wet loose activity increasing at lower elevations during the heat of the day. Be mindful of what terrain traps may be below you when navigating steep southerly aspects below treeline.
概要
Avalanche
No new activity has been forecasted across the region.
Snowpack
Warm temperatures and periods of sunshine on the 20th has heated the upper snowpack resulting in the formation of a crust on the surface up to 600m. This warming will have helped to settle the upper unconsolidated snow and will have promoted bonding.
Weather
We can expect periods of sunshine across the region today with light southerly winds and warming temperatures.
