Continually assess for wind slabs as you gain elevation.
At this time of year it only takes a short period of strong solar to increase hazard. Reduce your exposure to avalanche terrain and overhead hazard during sunny periods.

Avalanche Summary
No new avalanches were observed in the region on Sunday.
On Saturday, explosives triggered a size one wind slab avalanche. Pinwheeling was observed with daytime warming.
Snowpack Summary
5 to 10 cm of recent snow has been redistributed by northerly winds. This snow sits over a crust on steep solar slopes and previously wind affected surfaces on other aspects. The snow surface will likely become moist when the sun comes out.
A melt-freeze crust with facets above sits 50 to 120 cm deep. It has not produced any avalanches in the region in the past couple of weeks.
The mid to lower snowpack is considered well bonded at this point. Currently, we are not seeing the same basal weak layers and reactivity that many of the neighboring regions are experiencing this season.

Terrain and Travel Advice
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Wind slabs may be poorly bonded to the underlying crust.
- Avoid exposure to steep sun exposed slopes.
Problems
Wind Slabs
Winds have varied over the past few days meaning wind slabs could be found on all aspects. The most reactive wind slabs could be found on sun-exposed slopes where they may have formed over a crust.
Aspects: All aspects.
