The Canadian Avalanche Centre took what it says was the unusual step of issuing an alert for the Maritimes after a small avalanche in northern Nova Scotia on the weekend.
The centre says someone who was backcountry skiing on Saturday in the Wentworth Valley dropped in on a slope, triggering an avalanche about 15 metres wide and 30 centimetres deep.
The skier was carried to the bottom of the ravine but was not injured.
Another skier triggered a second slide but was able to avoid it.
"It was relatively small on the overall scale, but certainly even a small avalanche like that could produce serious consequences if people are in the wrong kind of terrain," said Karl Klassen of the Canadian Avalanche Centre in Revelstoke, B.C.
The centre is urging people to avoid steep slopes, gullies and other places where sliding snow could push them into a creek or lake.
"Any slope that's more than 20 or 25 degrees of incline is suspect right now," Klassen said. "And this includes relatively small pieces of terrain like kid's tobogganing hills, which could produce an avalanche large enough to bury a child or even an adult if the terrain features are wrong."
Klassen, a public avalanche warning service manager with the centre, said avalanches aren't common in Eastern Canada but can happen when the conditions allow for it.
"We've worked extensively with our partners in Newfoundland in the past and have issues alerts, but I think this is the first time we've done something like this in Nova Scotia."
Klassen said conditions should return to normal within a week as long as there isn't a significant snowfall.
