Avalanche Forecast Sea to Sky
Tuesday 5th February 2019
Wind slabs have formed on a variety of aspects due to shifting winds. Natural avalanche activity has tapered off but human triggered avalanches remain possible.
High - The weather pattern is stable
The arctic ridge will continue to bring cold, outflow winds and dry weather to the coast tomorrow. Thursday will see a slight change when the low slides south bringing some precipitation. Wednesday: Sunny with some cloudy periods. Treeline temperatures near -8 with light ridgetop winds from the North.Thursday: Cloudy with sunny periods. Treeline temperatures near -6 with light ridgetop winds from the North.Friday: A mix of sun and cloud with isolated flurries. Treeline temperatures near -5 with light ridgetop winds from the northeast.
On Monday, numerous wind slabs were easily triggered by the weight of a person up to size 1.5. With continued outflow winds and cold air natural avalanche activity will taper off but human triggered wind slabs remain possible through Wednesday.
40-50 cm of new snow from last weekend has been redistributed by strong southwesterly winds initially and now northerly winds. This sits on a crust on all aspects except north and possibly a mixture of weak feathery surface hoar or sugary facets in isolated sheltered terrain at treeline and below. The remainder of the snowpack is generally well-settled.

Expect to find wind slabs on a variety of aspects as winds shift from predominantly the southwest to the North.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Be cautious as you transition into wind affected terrain.Watch for signs of instability such as whumpfing, or cracking.
Aspects: All aspects.
