All massive Haute-Savoie: limited risk (level 2)

Wind at 4000 m: Southwest 60 and 100 km / h.

SNOW CONDITIONS:
Episodes of bad weather have not been very important this winter, the snow cover is low for early March. The slopes between south and west often have very little snow until about 1500 m, and even in 1800/2000 m steep. A high-altitude glaciers are generally in good condition but with already more beautiful crevasses.

For Monday:
The conditions do not change, departures on skis or snowshoes to toe will be from 1200 m, but with just a few cm of snow on the ground in the north will be more comfortable with the former hard layer but fine. Then taking the altitude, it will evolve on a more or less snow blown. The bumps and ridges of snow was icy.

STABILITY OF SNOW COVER:
Slabs located.
The snowpack will remain throughout much stabilized. Some, however, deserve slopes vigilance because of the passage of one or more persons might break a slab and trigger an avalanche. Typically modest in size, but that should not be overlooked.
These more fragile areas will be located rather close to the caps, collars, sometimes in the corridors, in directions north and steep. At high altitudes, most diverse directions may be concerned but still localized risk.
The risks of a voluntary departure is expected to be very low, possibly a fracture slab by overloading of the transport of snow.

TREND LATER RISK:
Towards risk rising a notch.
