Weather Forecast

Mountain Weather Forecasts are available here at avalanche.ca/weatherSPOTWX (http://spotwx.com) is a good resource for local scale weather forecasts.Remember weather forecasts are usually more accurate in the short term (1-2 days) than in the longer term (3 days or more).More details can be found on the Mountain Weather Forecast.

Avalanche Summary

Avalanche danger will rise during and immediately after a snow storm. If the temperature rises during or after a storm, or if there is rain, avalanche danger is likely to rise further. Avalanches are more likely if local reports include observations of weak layers.

Snowpack Summary

If there's enough snow to ride, there's enough snow to slide.Winter-like wind and storm slabs form readily in alpine bowls and around ridgelines and are often poorly bonded to the layers below. Its worth remembering that on smooth terrain (like glaciers, summer snow, grass, shale slopes and rock slabs) as little as 30cm of snow is enough to create avalanches.In some areas, early season weak layers may form. The most common scenario is a layer of sugary snow (facets) that can grow near the ground when temperatures get cold and there isn't much snow cover. Sugary facets may also be found on glaciers at the bottom of this seasons snowfall.
