BULLETIN FOR ESTIMATING THE RISK OF AVALANCHES
FOR MASSIVE SAVOIE
Valid off marked and open trails
THE FRIDAY 21 MARCH 2008
(Drafted Thursday, March 20)

ESTIMATE OF RISK FOR FRIDAY:
For Bauges and Beaufortain:
RISK MARK - Level 3 evolves HIGH RISK - Level 4
For Maurienne Vanoise, Haute Maurienne and Haute Tarentaise:
RISK MARK - Level 3

Wind General to 3000 m: west-northwest 60 to 100 km/h.

SNOW CONDITIONS:

The snow started at best around 1200 meters in the north, but sometimes not until 1800 meters in the south.
On the surface, the current snowpack Friday will be covered by a thick layer of snow locally windy.

STABILITY OF SNOW COVER:
NET DEGRADATION OF THE STABILITY WITH HIGH FALLS OF SNOW AND A LOT OF WIND

With heavy snowfall accompanied by violent gusts from the west to northwest, the situation will rapidly deteriorate. The risk will increase over time. It is expected normal attrition in all sufficiently steep slopes in various forms of heavy snow avalanches below 1800 meters in altitude powder, departures spontaneous slabs in the slopes loaded by the wind. Some of these avalanches may be a result of volume.

Of course the risk of inadvertent will also grow rapidly for skiers especially in the mass where the snowfall will be most intense. It should be confined to those areas known little steeper, located at altitudes modest and avoid guidance from a broad sector of the North (northwest to north-east) to East and South-East.
