BULLETIN FOR ESTIMATING THE RISK OF AVALANCHES
FOR SAVOIE
Valid off marked and open trails
FOR FRIDAY 4 APRIL 2008
(Drafted Thursday, April 3)

ESTIMATE OF RISK UNTIL FRIDAY EVENING:
On ALL MASS: LIMIT RISK - Level 2.

WEATHER OVERVIEW UNTIL FRIDAY EVENING:
Increasingly prevalent breaks despite some cumulus clouds on the hills. North wind weakening.

Insulated 0 ° C between 1500 and 1700 meters.
Wind at 3000 m: NORTH NORTHEAST to decreasing 30 km/h.

SNOW CONDITIONS:
They are still comfortable for an early April with heights of 30 to 150 cm from 1200 to 1600 meters and 150 to more than 200 cm to 2,000 meters and beyond.
The maximum snow skiing is located at about 1200 meters North and South 1400/1600 m.
On the surface, there are now about everything, spring conditions with crusts then subjected humidification especially below 2000/2500 meters, a little snow crusts overcoming oldest or a fund drive earlier or even snow or cardboard more or less hardened by the wind.

STABILITY OF SNOW COVER:
SOME SUPERFICIAL SLABS AND A LITTLE NATURAL ACTIVITY

There is this morning, around 1600/1800 meters, 1 to 10 cm of snow, locally 10 to 20 cm on Beaufortain and Northern Haute Tarentaise (or at high altitude).
If the snowpack is rather in a phase of stabilization (compaction and density layers), the first centimeters (5 to 30 cm), sometimes a few instabilities related to transport by wind. First there were the winds from the South with Foehn / Lombard Sunday and then to North West from Wednesday. Some slabs were therefore trained and n'adhérent not quite on a few sub-layers of snow slightly evolved (or snow particles recognizable rolled). The risk therefore remains localized accidental present with the possibility of rupture of a slab a little thick, brittle, when overloaded even by a single skier.
It must remain prudent in exhibitions in North-South is especially above 2200 meters in 2400 and particularly in Haute Maurienne and South-Vanoise. Distrust also in the event of adverse topographical configurations (corridors, steep slope failure, caps, etc. ..).

Furthermore, after a good night regel, humidification, which includes day may cause some wet snow slides in the sunniest slopes, as well as local small avalanches plate (Haute Maurienne) or snow recent (and Beaufortain Haute Tarentaise ).

TREND LATER RISK:
Stationary until Saturday with little change weather patterns.
