Avalanches may be triggered when heavy -LSB- NUMBER@1 -RSB- loads are applied , especially on a few generally identified steep slopes .

Avalanches are unlikely except when heavy loads -LSB- NUMBER@1 -RSB- are applied on a very few extreme steep slopes . Avalanches may be triggered on many slopes even if only light loads -LSB- NUMBER@1 -RSB- are applied . Avalanches are likely to be triggered on many slopes even if only light loads -LSB- NUMBER@1 -RSB- are applied .
