Valid Until: further notice

**NEW** Area closures for avalanche control are in effect intermittently from November to May. If not described in the bulletin headline below, the area is open. For more information and maps, click the link below under "Resources".

Reports are showing a transition to a supportive summer snowpack in most areas. Expect hard snow conditions on cold mornings and increasing avalanche hazard in steep snowy terrain on hot days. [IJ]

Low
  • Generally safe avalanche conditions. Watch for unstable snow on isolated terrain features.
  • Natural and human-triggered avalanches unlikely.
  • Small avalanches in isolated areas or extreme terrain.
Moderate
  • Heightened avalanche conditions on specific terrain features. Evaluate snow and terrain carefully; identify features of concern.
  • Natural avalanches unlikely; human-triggered avalanches possible.
  • Small avalanches in specific areas; or large avalanches in isolated areas.
Considerable
  • Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding and conservative decision-making essential.
  • Natural avalanches possible; human-triggered avalanches likely.
  • Small avalanches in many areas; or large avalanches in specific areas; or very large avalanches in isolated areas.
High
  • Very dangerous avalanche conditions. Travel in avalanche terrain not recommended.
  • Natural avalanches likely; human-triggered avalanches very likely.
  • Large avalanches in many areas; or very large avalanches in specific areas.
Extreme
  • Avoid all avalanche terrain.
  • Natural and human-triggered avalanches certain.
  • Large to very large avalanches in many areas.

Weather Forecast

Avalanche Canada's Mountain Weather Forecast is a great resource for regional weather.

SPOTWX is a resource for weather forecasts at a local scale.

Snowpack Discussion

There is more residual snowpack at upper elevations than normal for this time of year. Expect to find seasonal snow patches extending to lower elevations than typical. These can make for good travel if frozen and supportive but can be a source of avalanches and rockfall on warm days.
