Alpine: LOW caution on solar aspects
Treeline: LOW
Below Treeline: LOW
Travel Advisory: There are areas of hard slab in lee alpine start zones. These slabs are between 10-60 cm deep. For the most part it has taken a large trigger such as a cornice drop to trigger this slab though there have been reports of skier triggered avalanches to size 2.5. Cornices remain tender with the daily temperature swings and use caution on solar aspects.
Avalanche Activity: The slabs that we saw running on Saturday are tightening, reports of avalanches over the past two days has slowed down. There are still hard slabs in lee alpine start zones that may be able to be triggered by the weight of a skier.
Snowpack: There is a variety of snow surfaces in the alpine from dry hard slabs, melt-freeze crusts and areas of wind scoured. These various layers of snow are all sitting over a very hard crust from April 9th. The melt-freeze cycle has left us with several crusts in the upper snowpack as well leaving many areas with rough refrozen surfaces. The snowpack below treeline has become isothermic. Above 1100m this is all now covered with a dusting of new snow.
Weather: A weak low pressure system will give us unsettled conditions through Thursday.
