SNOW AND AVALANCHE BULLETIN FOR HAUTE SAVOIE
(VALID OFF OF OPEN AND MARKED RUNS)
PREPARED ON MONDAY 31 MARCH
FOR TUESDAY APRIL 1
ESTIMATE OF RISK UNTIL TUESDAY EVENING:
All massive Haute-Savoie: limited risk (level 2) that evolves marked risk (level 3) with the sun

WEATHER OVERVIEW UNTIL TUESDAY EVENING:
Cloudy tonight, the sky brightened especially at high altitudes. Rather cloudy Tuesday with cumulus clouds on average mountain

Isothermal 0 1700 2200 m.
Wind around 2000 m: north-east, 30 km / h.
Wind around 4000 m: low turning north in the afternoon.

SNOW CONDITIONS:
It's good for early April, skis or snowshoes can be put on from 1200/1300 m in the north.
At 1500 meters, measuring 20 cm to more than 1 m of snow depending on sun exposure.

Quality of snow for Tuesday:
There is a layer of fresh snow powder in altitude above 2200 m often based on snow or hard crust. Below 2000 m, fresh snow is much heavier and wetter mate at low altitude, it is based on a sub-layer wet well, barely regelée.
During the day on Tuesday, snow s'humidifiera well and will increase on average in the mountain sunny slopes, sometimes even rotten in places. Towards areas prone to kiss the snow is a little blown.

STABILITY OF SNOW COVER: Avalanche activity in the sun

On Monday, 10/20 cm of snow on average fell over 2000 m, 30 cm locally as the Aravis.

The risk of an avalanche with the passage of a skier is not very important and will be limited to a few departures well located on steep slopes. These potential avalanches are not very large in general, with the recent rolling under snow skis. It will be possible guard slabs formed by wind kiss rather towards the peaks above sea level.

By day Tuesday, it is to be expected fairly quickly in the morning to normal attrition avalanches and heavy wet snow on average in the steep mountain slopes warmed by the sun, directed primarily East, South and West. These avalanches generally prevail that the recent snow, but below 2000 m, a possible avalanche could take more volume in scraping snow underlying much wetter. A skier could also encourage the departure of such avalanches and heavy wet cutting a steep slope.

TREND LATER RISK: slight decline.
