Observations indicate that most natural dry snow slab avalanches release during storms as a result of rapid loading from snowfall... Observations also indicate that avalanche activity usually increases within a few minutes of the onset of rain-on-snow. These avalanches typically release as slabs several hours before liquid water has penetrated to the sliding layer... The mechanism of release of these immediate-type avalanches has been a puzzle; it is not clear how the snow at the shear plane at depth knows that it is raining at the surface... these avalanches release much sooner than would be expected if loading and/or lubrication caused the failure.  1, record 1, English, - immediate%2Dtype%20avalanche

Lorsqu'une chute de pluie suit une chute de neige [...] dès le début de la pluie [...] on observe quelques avalanches avec départ en plaque, le plus souvent de faible épaisseur [...] et concernant la neige récente : on parle d'avalanche immédiate; au bout de quelques heures [...] on observe des avalanches plus importantes, avec départ en plaque et pouvant concerner des couches de neige anciennes : on parle d'avalanche retardée.  1, record 1, French, - avalanche%20imm%C3%A9diate

Observation is the key to safe travel in avalanche terrain. Observation not only of the mountain scenery but of the multitude of clues indicating snow conditions visible to the perceptive traveller. Some of the things you should look for are as follows: Evidence of Avalanching. ... Wind Direction. Aspect. The aspect of a slope to both sun and wind is most important. ... The Snow Surface. ...  2, record 2, English, - field%20observation

Travelers in the backcountry usually make mental notes of the observed factors and draw immediate conclusions about snow stability. Snow safety operations, however, usually retain written records of the observations. The records are needed for future analysis, for application in forecasting models, and for communication with other operations and agencies.... Observations should be carried out accurately, reliably, and according to standards(when standards for data collection exist).... Every observation should be relevant to snow stability.... Observation should be carried out in places where weather and snow conditions simulate avalanche starting zones as closely as possible...  3, record 2, English, - field%20observation

La prévention et gestion du risque (spatial) d'avalanches sur un site. [...] Une étude locale du site : Trois analyses sont engagées simultanément à ce premier stade de l'expertise : (i) l'étude des critères physiques du site avalancheux [...] (ii) l'étude de ses conditions climatiques hivernales [...] (iii) enfin, l'étude des avalanches historiques [...] Ces trois enquêtes consistent à rassembler les données de base nécessaires à l'étape suivante [soit, la description de scénarios d'avalanches majeures], mais constituent déjà des expertises en elles-mêmes. Il y a intérêt à les mener conjointement car elles reposent évidemment en grande partie sur le résultat des observations de terrain à effectuer sur le site.  2, record 2, French, - observation%20de%20terrain
