SNOW AND AVALANCHE BULLETIN FOR HAUTE SAVOIE
(VALID OFF OF OPEN AND MARKED RUNS)
PREPARED ON SUNDAY MARCH 16
FOR MONDAY MARCH 17

ESTIMATE OF RISK UNTIL MONDAY EVENING:
All massive Haute-Savoie:
Higher than 1800/2000 m: marked risk (level 3)
Lower than 1800/2000 m: limited risk (level 2)

WEATHER OVERVIEW UNTIL MONDAY EVENING:
Unstable and sometimes stormy, snowfall since 1000 m, decreasing Monday
Layer expected to 2000 m: 20/40 cm blown.
Temperature to 1500 m -1 to +3 dg.

Isothermal 0 1500 m.
Wind at 2000 m: Southwest 30 to 70 km / h decreasing Monday.
Wind at 4000 m: West 70 kph turning northwest in decreasing 40 km / h.

SNOW CONDITIONS:
They are scarce in a general way lower than 2000 m above is correct.
In the high mountains, glaciers are in good condition but large cracks are already open and a few snow bridges become fragile.
Monday, we can start skis or snowshoes to toe m since 1200, but often on a layer on the ground until about 1800 meters. In the north, it will be more comfortable with the former hard layer remaining.
Quality of snow for Monday:
It will evolve over a blown snow, sometimes powder in the palm of bowls.
In the high mountains, snow corrugated compacted.

STABILITY OF SNOW COVER:
RATHER POOR ON MANY SLOPES.
In the night from Saturday to Sunday, it fell 5/10cm at 2000 m.
This layer has been tamped down a bit following the temporary light Sunday morning.
But this episode of snow (with wind and snow rolled at times), which continues to form slabs potentially avalanching that even one person can break. This will avoid all areas near the blown passes, caps, broken slopes, senior corridors. Several guidelines can be involved, knowing that in slope between East and North routes, a thicker slab of the past week could be sought (big break).
Some departures will spontaneous forms slabs by overload effect created by the wind (rather breaks on the north slope or at rimayes), some cast in the corridors.

TREND LATER RISK:
Overall stationary risk.
