Limited risk (level 2).

Isothermal 0 2000 m.

Quality of snow for Monday:
A thin layer of snow and improperly filed becoming wet in the sun on a hard or brittle average mountains, sometimes on an old coat powder remained in the north higher than 2000 meters. In high mountain snow often wavy, powdery housed in the corners of high winds.

STABILITY OF SNOW COVER:
SOME SLABS WITH WORK AND NATURAL NO TRIVIAL.
The new slabs from the layer of the night, are expected to locate near the passes and peaks, and be modest in size but can be broken by the mere passage of a person. Some slabs, the oldest and coarse, are still in place higher than 2500 m in slope rather geared more towards the north and bars seracs in portions of corridors.
On Monday, castings and small avalanches of snow will trigger s'humidifiant (natural or caused by one person) in steep, moreover mixed. Activity probably more intense around mid-day. These flows remain modest in size but in certain situations topographic (corridor bottleneck, rock) the consequences could be amplified. Of therefore take into account the ground.

TREND LATER RISK:
Tuesday, windy and variable time, a level of risk stationary.
