Hazard LevelAvalanche Probability
Very High

Avalanche Hazard

Widespread natural avalanches will occur, often continually. Frequent, medium to large sized avalanches, with long run outs, will occur on most aspects; the snowpack is weakly bonded in these locations. Rare extreme conditions.

Travel Advice

Widespread natural avalanches will occur. Human triggered avalanches will occur with single person loading on most slopes. Experience in avalanche hazard evaluation essential. Good visibility and very good route finding in mountain terrain essential. Awareness and avoidance of runout zones at low altitudes essential. Good group management and safe travel using mountain features essential.(eg: Ridges, protected slopes)

Travel Advice

Natural avalanches will occur. Human triggered avalanches will occur with single person loading. Experience in avalanche hazard evaluation essential. Good visibility and very good route finding in mountain terrain essential. Awareness and avoidance of runout zones at low altitudes essential. Good group management and safe travel using mountain features essential.(eg Ridges, protected slopes)

Natural and Human triggered avalanches will occur.
Considerable

Avalanche Hazard

Medium to large sized natural avalanches possible. In locations indicated in the reports, human triggered avalanches are likely; The snowpack is poor to weakly bonded in these locations.

Travel Advice

Natural avalanches possible. Human triggered avalanches likely with single person loading. Experience in avalanche hazard evaluation important. Good visibility and very good route finding in mountain terrain is necessary. Good group management and safe travel using mountain features necessary.(eg Ridges, protected slopes)

Natural Avalanches possible.
Human triggered avalanches are likely.
Moderate

Avalanche Hazard

Large natural avalanches unlikely. Avalanches in steep locations are possible. Human triggered avalanches possible. The snowpack is only moderately well bonded on some steep slopes, or moderate to poorly bonded, in isolated steep locations as indicated in the reports. Elsewhere generally well bonded.

Travel Advice

Human triggered avalanches possible. Experience in avalanche hazard evaluation important. Good visibility and good route selection required, especially in steep locations as indicated in the reports. Good spacing between persons is necessary to reduce loading on slopes. Good group management and use of safe travel mountain features important. (eg Ridges, protected slopes)

Natural Avalanches unlikely.
Human triggered avalanches possible.
Low

Avalanche Hazard

Natural avalanches unlikely but in some conditions small avalanches in steep locations are possible. Human triggered avalanches not likely. Generally the snowpack is well bonded and stable.

Travel Advice

Human triggered avalanches not likely, generally safe travel conditions

Natural Avalanches very unlikely.
Human triggered avalanches not likely.

The SAIS forecaster team would like to thank you for your support over the past winter and wish you a good summer.

Forecasted Snow Stability and Avalanche Hazard

Avalanche hazard considerations should always be part of any winter hill goers daily plans and we would recommend that when currently venturing into the hills, continue to note any snow and weather conditions in respect of any potential hazard. Be prepared to modify your plans accordingly. Cornices remain a hazard on many slopes, these are unpredictable and prone to collapse.
