FROM AVALANCHE CANADA-SEA TO SKY:

We've concluded our daily avalanche forecasting season. However, avalanche hazards continue well into spring. The Spring Conditions page provides guidance for mountain travel over the coming weeks.

Enjoy the long days of spring! We'll see you in the fall when the snow returns.

Early Season: Fri, 29 Apr

The avalanche danger is variable and can range from Low to High. Travelling early in the day is recommended, as conditions can change rapidly in short periods of time due to daytime warming. Pay careful attention to the integrity of the surface crusts formed overnight and rising air temperatures during the day. Dry slab avalanche danger may also exist during spring snow storms. Field Observations for your area may be available at the Association of Canadian Mountain Guides (ACMG) Mountain Conditions Report Website: http://www.mountainconditions.com.
