Terrace and Kitimat are under a considerable avalanche danger rating as conditions are expected to worsen through the day, according to Avalanche Canada.
Accumulations of storm snow are expected to occur, leading to larger and more susceptible avalanches. It has been advised that backcountry travelers limit their use of steep terrain, keeping an eye out for instabilities, so they can relocate to safer terrain if needed.
Avalanche Canada said the sensitivity of slabs in storm snow is increasing, especially in steep, rocky and wind-blown areas, which are most at risk for dangerous slab avalanches.
Weak snow layers deep within the snowpack have also been brought to attention due to the potential consequences. Although the possibility of triggering them is low it is still possible that a large load could cause them to fail.
Recent activity in the region highlights the risk. On Sunday, north of Stewart, two avalanches occurred, with one being triggered by a vehicle while the other was naturally caused. Previously, a size three persistent slab avalanche was remotely triggered on a steep, rocky, north-facing slope.
Wet loose avalanches have been taking place as a result of the current warm weather and sunshine. However, according to forecasts, there may be some slight reduction in such occurrences as cooler and cloudy weather prevails.
Avalanche Canada is advising anyone heading into the backcountry around Terrace and Kitimat to use extra caution, avoid high-risk terrain, and stay alert to changing conditions throughout the day.
