DEF

An avalanche consisting of snow which contains liquid water.

CONT

Wet snow avalanches develop in the same manner as dry snow avalanches but have no powder cloud. The moving snow is dense ... Wet snow avalanches tend to flow in channels and are easily deflected by irregularities in the terrain. After wet flowing motion stops, deposited debris commonly has channels and ridges on the surface. Because of their high density, wet avalanches are much more difficult to fight against than dry avalanches.

CONT

Avalanches can also be characterized as being either "wet" or "dry" based on the amount of free water in the snow. Free water is liquid water, from melting or rain, that is present between the frozen crystals of a snow layer. Wet avalanches occur when the temperature of the snow is above freezing and there is free water present in the snowpack.

CONT

Wet-snow avalanches are expected this afternoon as the day warms up. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

wet-snow avalanche: term officially approved by the Avalanche Bulletin Terminology Standardization Committee.

CONT

L'avalanche de neige mouillée s'écoule généralement plus lentement qu'une avalanche de neige sèche, et s'arrête par conséquent sur une distance plus courte. Toutefois, à cause de sa grande densité, elle exerce une importante force sur les obstacles. Parfois désignée comme «avalanche de printemps».

CONT

Des avalanches de neige mouillée sont prévues cet après-midi alors que les températures se réchaufferont. [Exemple entériné par le Comité d'uniformisation de la terminologie des bulletins d'avalanche.]

OBS

avalanche de neige mouillée : terme uniformisé par le Comité d'uniformisation de la terminologie des bulletins d'avalanche.
