|
LOW |
The snowpack is generally well bonded and stable. |
Natural avalanches highly unlikely. Human triggered avalanches unlikely. |
Travel is generally safe. Normal caution advised. |
|
MODERATE |
The snowpack is moderately well bonded on some steep slopes, otherwise generally well bonded. |
Natural avalanches unlikely. Human triggered avalanches possible. |
Generally favourable conditions. Routes should be selected with care especially on steep slopes. |
|
CONSIDERABLE |
The snowpack is moderately to weakly bonded in most places. |
Natural avalanches possible. Human triggered avalanches probable. |
Backcountry skiing and travel should only be carried out by experienced persons able to evaluate avalanche hazards. Steep slopes of the aspect and altitude indicated should be avoided. |
|
HIGH |
The snowpack is weakly bonded in most places. |
Natural and human triggered avalanches likely. |
Backcountry skiing and travel should be restricted to low angled slopes; areas at the bottom of slopes may be hazardous. |
|
EXTREME |
The snowpack is generally weakly bonded and largely unstable. |
Widespread natural or human triggered avalanches certain. |
No backcountry skiing or travel should be undertaken |
