Small avalanches can still have serious consequences in extreme terrain. Carefully evaluate your line before you commit to it.
Until we get more snow or warming temperatures, avalanche hazard will result from wind redistributing surface snow. Check for reactive pockets in open and exposed locations where you find cold, dry snow.
No new avalanches have been reported.
Last weekend, several cornice falls were observed and triggered large avalanches on the slopes below. Give cornices a wide birth, and expect large and looming cornices to remain fragile, especially with daytime warming.
A skiff of fresh snow covers a widespread crust that exists up to roughly 1300 m. This crust may soften with daytime warming at lower elevations.
At upper elevations, snow is likely to be wind-affected. Increasing winds may form fresh, reactive pockets of dry snow. Large, fragile cornices can be found on exposed ridgelines and should be given a wide berth. Soft, dry snow may still be found on north-facing alpine slopes.
In some areas, particularly in the Haines Summit, a weak layer of facets or surface hoar is buried 50-80 cm. This layer is unlikely to trigger from the weight of a rider, but concern exists with very large loads like cornice falls.
