BULLETIN FOR ESTIMATING THE RISK OF AVALANCHES
FOR SAVOIE
Valid off marked and open trails
FOR TUESDAY 25 MARCH 2008
(Drafted Monday, March 24)
ESTIMATE OF RISK UNTIL TUESDAY EVENING:
On ALL MASS: RISK MARK - Level 3
WEATHER OVERVIEW UNTIL TUESDAY EVENING:
Overnight rather agitated with 5 to 15 cm of snow and wind. Back in the
morning warm among some cumulus sometimes threatening (sleet isolated).
Insulated 0 ° C: 400 meters. Wind at 3000 m: Northwest 80 and then 30 to 50 km/h.
SNOW CONDITIONS:
They are excellent again as in the heart of winter with a bleached soil
from 300/500 meters and a "skiability" from 1000 meters. The thickness
approaching 60 to 100 cm to 1200/1500 meters and reach 100 in 2000 to
170 cm meters locally over 250 cm as Beaufortain or above 2500 meters.
The snow surface is usually powder in the mountains (humidification
possible only under 800/1200 meters), sometimes nearly blown ridges
with accumulations.
STABILITY OF SNOW COVER:
NEW SLABS AND SOME NATURAL DEPARTURES
Again, 5 to 15 cm of snow dropped since 1500 meters below the showers Sunday is a cumulative 48 hours in 10 to 30 cm.
Nevertheless, the slowdown continues, with special "effective" below
2000 meters. However, new snowfall in progress and especially the wind
waited Northwest will promote the formation of new slabs, rather
above 1800/2000 meters in the Bauges and 2200/2400 meters on the other
mountain.
So we will find a rather superficial instability marked on most of our reliefs with 15 to 40 cm of snow often windy on the sub-layers and advanced little fragile (recognizable particles, snow rolled, etc.). The risk of rupture when overloaded even by a single skier continues to be important, particularly with exposure to South-North is sometimes Northwest. Please note that these triggers caused, in the form of slabs more or less friable, very locally can expand (warp exceeding 50 cm and important vertical). It has been reported every day at least one departure accidental above 2000 to 2500 meters, great caution is therefore required in off-piste.
In addition, it is always possible that natural departures occur during falls and with the return of clouds. They must be confined to a few small slides and avalanches even though a larger is not completely ruled out.
TREND LATER RISK:
Stationary.
