Use extra caution in the alpine where rider triggerable wind slabs could still be found.

On the North Shore a diminishing snowpack will make for challenging travel.

Summary

Confidence

High

Avalanche Summary

No recent avalanches have been observed in the North Shore mountains.

Snowpack Summary

A surface crust exists on or just below the surface to the top of the North Shore mountains.

Higher elevations in other parts of the region have widespread wind-affected surfaces and the potential for wind slab over facets. The snow surface will likely become moist throughout the day at lower elevations.

Conditions remain rugged at lower elevations.

Terrain and Travel Advice
