Avalanche Summary
A snowstudy flight today was unfortunately obscured mostly by cloud. However there was some visibility and a wide spread avalanche cycle appears to have happened along the spray. Most crowns were mostly filled in from the recent strong to extreme winds.
Travel in avalanche terrain requires cautious route-finding and conservative decision making.
Snowpack Summary
This last storm has deposited between 10-25cm snow (10cm to the North of the Spray and 25cm near the Dogleg area). Expect another 5-10cm by Tuesday morning. The milder temperatures along with strong winds have settled most of this snow into some sort of slab at all elevations. Recent strong/extreme winds in the Alpine have most likely left some widespread wind slabs, especially in lee features and cross loaded gullies. All of this is sitting on top of the Jan 30 interface (mostly a denser layer) and then below this is all facets. The forecasters do not trust the snowpack at the moment and are staying clear of avalanche terrain.

Terrain and Travel Advice
- Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
- Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.
- Wind slabs are most reactive during their formation.
- Be careful as you transition into wind-affected terrain.
