BULLETIN FOR ESTIMATING THE RISK OF AVALANCHES
FOR SAVOIE
Valid off marked and open trails
FOR WEDNESDAY 9 APRIL 2008
(Written Tuesday, April 8)

ESTIMATE OF RISK UNTIL WEDNESDAY EVENING:
On all except the Bauges massive lack of information:
-- Above 2200/2400 m: RISK MARK - Level 3
-- Below 2200/2400 m: LIMIT RISK - Level 2

WEATHER OVERVIEW UNTIL WEDNESDAY EVENING:
Clearing night and morning. Precipitation from the middle of the day. Limit rain-2500 m. We expect less than 10-2700 m. Foehn and Lombarde near the border.
Isothermal 0 2200 2700 m.
Wind General 3000 meters: Southwest to South 20/40 and 40/60 km / h.

SNOW CONDITIONS:
They are good, with layers of snow on the ground often higher than the averages in early April, locally near or below. There is at 1500 m: 0 to 60 cm to 100 cm locally Beaufortain, 2000 m: 50 to 180 cm by 280 cm locally Beaufortain. The lower limit of skiable snow falls between 1000 and 1900 m.
On the surface, in the morning, a little snow recently, sometimes windy, snow covers a crust by regel below 1800 m in northern steep slopes undergoing somewhat the effect of solar radiation, and higher elsewhere, until very high altitude in South steep slopes sunny, then it becomes damp during the day. In other sectors suffering somewhat the effect of solar radiation, the recent snow is thicker, more or less packed when it is not cardboard or cured by the wind. On Wednesday morning, it will be wet by rain and regelée below 2000 m, covered with a bit of snow earlier.

STABILITY OF SNOW COVER:
A LITTLE NATURAL ACTIVITY and some SUPERFICIAL SLABS
Snowfall and wind expected will form some new superficial slabs, especially over 2500/2700 m and in various sectors especially near the border. Other superficial slabs, formed recently by winds north and then west to south-west with Foehn / Lombarde remain above 2200/2400 m. Their adherence to the crust or snow more or less recent (or angular) is not assured. Some artificial and accidental releases to be reported this morning, friable plaque or hard sometimes thick above 2200 m above all on display Northeast.
With the wind, sun, then redoux rainfall, few natural attrition will occur sufficiently steep slopes, a few in all exhibitions. The cast of wet snow surface more or less onerous occur mostly below 2500/2700 m. The Avalanche substantive wet snow can also occur in steep grassy, especially below 2000/2200 m and exhibitions South East to South-West, particularly in the Bauges. Above 2500/2700 m, the surface prevail cast of snow or more dry patches more or less friable. A fortiori, such overloading the passage of one or more skiers can promote the initiation of these flows or avalanches.
In particular, a single skier can stall a surface slab lasts more or less then that can cause the breakdown of another slab more or less buried. Overloading more or less strong as the passage of several skiers can stall a slab sometimes quite thick. This risk remains stronger accidental above 2200/2400 m in the morning and then a little higher in the afternoon, and the slopes undergoing somewhat the effect of solar radiation exposure including Northwest North East even East to southeast.

TREND LATER RISK:
Stationary or rising slightly Thursday.

ON MONDAY 7 APRIL 2008
(Drafted Sunday, April 6)

ESTIMATE OF RISK FOR MONDAY:
For all the massive Savoie
Above 2400 m: RISK MARK - Level 3
More than 2400 m below: LIMIT RISK - Level 2

WEATHER HIGHLIGHTS:
Precipitation low, moderate temporarily, in the night of Sunday to Monday accompanied by violent gusts of wind. Improving Monday with cloudy. It expects 10 to 25 cm of snow with a maximum rain / snow below 1000 meters.

Isothermal 0 300 2300 m.
Wind at 3000 meters west 30 to 80 km / h and then southwest 40 km / h Monday afternoon.

SNOW CONDITIONS:
The snow is often reduced below 1300 to 1500 meters, it is normal for the season above 1800 meters. The thickness of snow reached 80 to 180 cm at 2000 m and even locally over 2 meters.
The maximum snow skiing is about 1200 m in northern and 1600 m in the south.
Monday, a small layer of snow will cover the snow often spring up to 2200 m in northern and 2700 m in the south. Further up, the snow is lighter but sometimes cardboard or cured by the wind.

STABILITY OF SNOW COVER:
SOME VERSANT SHADING SLABS IN HIGH ALTITUDE

The snowpack stabilizes generally fast enough between the disturbances, snow and recent cup is rapidly becoming more dense. But at high altitudes, especially in areas somewhat sunny, the cohesion is slower and the snowpack remains fragile.

It essentially is where the risk of inadvertent. It must therefore remain particularly suspicious over 2400 metres in a wide area north (between north-east and north-west), especially near the peak or changes slope. Especially as the south-westerly wind will form new surface slabs in these areas. Elsewhere the risk is reduced but some very dangerous areas persist locally particularly in the slopes is to the south-east and in some corridors very steep mountain in various slopes.

In addition, the layer of snow may cause a few drips or small avalanches particularly during the light during the day.

TREND OF RISK FOR TUESDAY:
Stationary or rising slightly with a weak disturbance flow southwest.

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.

HIGH-MAURIENNE BEAUFORTAIN AND:
Above 2200/2400 m: RISK MARK - Level 3
Below 2200/2400 m: LIMIT RISK - Level 2.

WEATHER OVERVIEW UNTIL WEDNESDAY EVENING:
Beautiful in the morning and then covering. Isothermal 0 ° C: 1600. Wind at 3000 m: North / Northwest 60 to 100 km / h.

SNOW CONDITIONS:
The conditions are wintery with snow heights above the average and end of March. In Bauges, Beaufortain, the snow begins around 1100 through the North and there are 200 to 250cm to 350cm at 2000m and 2500m. In Tarentaise, beginning in 1300 skiing in North heights approaching 150 to 200cm at 2000m. In Maurienne heights are a little lower with 80 to 120cm to 170cm and 2000m altitude. The powdery snow becomes less and more blown aloft with the north wind. In the high-mountain glaciers remain well plugged, faces some northern portions are steep ice.

STABILITY OF SNOW COVER:
SOME SURFACE SLABS IN SOUTH VERSANTS

Snow totals are 48 hours from 5 to 10cm in general but 20/30cm in Haute-Maurienne and Beaufortain. There have been several reports avalanches in Haute Maurienne (natural surface flows in the south and a few slabs in North 2000/2200m above).

Recent cuts show a wintery snowpack and cold with snow in March thick enough (more than 1m) in the course of settling. Sub-resistant layers sometimes less fragile and locally are buried. The first 10/20 cm may instability if snow or if the wind picks up.

In the Bauges, small slabs near the peaks and southern corridors.

In Beaufortain, Bise rises tonight, distrust Wednesday morning in the bowls charged by the wind, including Southwest to West. Above 2200/2400m, sometimes thicker slabs (20/30cm).

In Haute-Maurienne, the winds of North should carry the recent snow and light. New thick accumulations sometimes above 2200/2400m (30/40cm) should present a risk to the skier. The slopes at SOUTH SOUTH-EAST must be avoided.

In other massive below 2200/2400 meters, good regel and snow becomes very little. The risk of avalanches is low. Above 2200/2400 meters, the wind carries North snow remained light and it is feared the formation of small surface slabs (10cm), including by SUD. In the high-mountain, a final approach by paying SUD, with a portion exposed in the event of a fall (rock bars for example), can be very delicate locally (small slab causing the fall).

TREND LATER RISK:
Up with the snowfall provided Wednesday evening.

WEATHER OVERVIEW UNTIL TUESDAY EVENING:
The sky emerges this night, good weather Tuesday. Isothermal 0 ° C up to 2200m in the afternoon. Wind at 3000 m: calm and then north to north-east 20/30 km / h.

SNOW CONDITIONS:
The conditions are still winter with Snow Depth very important and superior to the average and end of March on all our mass. In Bauges, Beaufortain, the snow begins around 1000 through the North and there are 200 to 250cm to 350cm at 2000m and 2500m. In Tarentaise, early skiing at 1200m in North heights approaching 150 to 200cm at 2000m. In Maurienne heights are a little lower with 80 to 120cm to 170cm in 2000m and alttude. Snow is good skiing with 10 to 30cm deep powder at 2000m according to the mass. In the high-mountain glaciers remain well plugged with the month of March good snow. However, some north facing portions are steep ice.

STABILITY OF SNOW COVER:
SOME SURFACE SLABS IN NORTH VERSANTS

It snowed since Sunday evening, 10 to 20cm in Bauges, Beaufortain and Haute-Maurienne and less than 5cm elsewhere. South winds measured at 50 to 100 km/h accompanied the snowfall. On Monday, he still low and snow fell 5cm on average, 10cm near the border in the Maurienne. The avalanche activity is declining with 10 cast generally observed over 2200m with either Departures Ski exhibitions in North and natural flows rather South.

The recent cuts of snow show a snowpack winter, cold with snow in March, fairly thick (more than 1m) and ongoing slowdown, placed on the sub-layers may be less resilient and fragile locally (flat) or on Hard crusts.

In the Bauges, a few patches of surface were formed near the peak, particularly in the hills north to north-east and can come with the passage of skier. With redoux, some cast in southern slopes are likely in the afternoon.

In Haute-Maurienne and Beaufortain, the slabs recently formed on the surface might be a little thicker (20/30cm). Beware especially exhibitions in North Northwest a little more responsible. Old largest accumulations are present locally in North-East as well. In the afternoon, wet snow avalanches are possible in the South.

On the other mountain, it snowed less the risk of surface slabs are lower. It remains old accumulations (20/30cm) generally in the high mountains (above 2200/2400m) and especially in North-East with a sub-layer may be less fragile buried near peaks. A little natural casting is possible in the afternoon.

TREND LATER RISK:
Up with the north wind that rises.

ESTIMATE OF RISK UNTIL MONDAY EVENING:
In any massive Savoie:
-- Above 1800/2000 m: RISK MARK - Level 3
-- Below 1800/2000 m: LIMIT RISK - Level 2.

WEATHER OVERVIEW UNTIL MONDAY EVENING:
Many clouds and precipitation. Limit rain-2000 to 1000/1300 m. The strong winds aloft South falters in the morning and then turns to the east. Foehn and Lombarde fade in the early morning and then steadily during the day. It expects 10 25 2000 m.
Isothermal 0 ° C to 2400 and 1400 meters.
Wind General to 3000 m: South to the South-East 50/80 and 20/40 night kph, South south-east then east, then north-north-westerly during the day 20/40, then 20/40 and 10/20 km / h.

SNOW CONDITIONS:
They remain good, with layers of snow on the ground that are closer to averages for the end of March but still mostly higher. There are 10 to 90 cm at 1500 m and 120 cm in Bauges and Beaufortain, 60 to 180 cm at 2000 m and 260 cm in Beaufortain. The lower limit of snow skiing ranges between 1000 and 1800 m.
The snow surface became wet and hardened by the regel morning below 1800/2000 m North steep slopes and until very high altitude, steep southern slopes, softens during the day and then extends humidification higher altitudes. The recent lighter snow remains essentially on slopes Northwest to north-east when it is not hardened by the wind mostly near the border. Monday, she coats of snow to-1500 m.

STABILITY OF SNOW COVER:
NATURAL ACTIVITY AND SOME WIND SLABS
The strong wind that blows from the South currently senior Bauges massive internal and generates a strong wind and Foehn Lombarde across the border until Vanoise and lower valleys form, with the recent snow still not consolidated, a few superficial new slabs more or less a little harsh at all altitudes and in a wide variety of exhibits (especially near the border). The snowplow moderate to strong East to South to the North and West is sometimes seen in all mass.
Other small surface slabs formed recently by strong winds from west to Northwest remain mostly peaks of the Bauges senior massive internal and on the edge of Piedmont. The adhesion of these slabs is not assured. Some have décrochées spontaneously in southern slopes in recent days, while others have been triggered accidentally or artificially at 2200 m.
The snow will still be expected mainly windy during the night. The slabs will be gradually covered with snow lighter.

Some natural attrition will occur over the precipitation.
Under 1500/1800 m, rain will encourage some cast and sometimes wet snow avalanches more or less onerous, sometimes taking entire snowpack in place. In sunny areas shortly (as in exposed slopes in the Northwest in the north-east), some may spill over roads. And such an overload the passage of one or more persons on skis, snowboards or snowshoes can promote their outbreak.
Above 1500/1800 m, it is superficial flows and avalanches rather mean drier snow (powder or slab more or less friable), which will occur in sufficiently steep slopes. A fortiori, a small surcharge as the passage of a single skier can be enough to trigger a surface slab more or less friable, or sometimes a buried slab but little thicker. A higher surcharge as the passage of several skiers sometimes can lead a fairly large amount of snow especially in the high mountains.

Of all the mass of Savoy:
-- Above 1800/2200 m: RISK MARK - Level 3
-- Below 1800/2200 m: LIMIT RISK - Level 2 evolves day RISK MARK - Level 3.

WEATHER OVERVIEW UNTIL SATURDAY EVENING:
Passages of clouds at night with very weak precipitation (less than 5 cm of snow). Then sunny day. The wind from west-northwest wind fort at night in high mountains, but also temporarily lower especially at the edge of Piedmont and on the tops of the Bauges.
Isothermal 0 ° C to 2000, then 1400, then 2400 meters.
Wind General to 3000 m: West and Northwest night 20/40 locally 50/70 km / h on the edge of Piedmont, Northwest and West 20/50 and 10/20 day km / h.

SNOW CONDITIONS:
They are excellent, with layers of snow on the ground in most cases higher than the averages for the end of March, very close to or lower than locally. There are 20 to 100 cm at 1500 m and 140 cm in Bauges and Beaufortain, 70 to 190 cm at 2000 m and 280 cm in Beaufortain. The lower limit of snow skiing ranges between 900 and 1500 m.
The snow surface is crusty in the morning below 1000/1500 m. In the slopes most exposed to the effects of solar radiation, the crust is superficial until 1500/1800 m then covered with a little snow recently until at least 2300 m. Elsewhere, the recent snow cover is more or less packed, there is still little consolidated from 15 to 35 cm at 2000 m, or cardboard or cured by the wind mostly in the high mountains. Saturday morning, the surface crust may be present earlier.

STABILITY OF SNOW COVER:
SOME SLABS AT ALTITUDE and SOME NATURAL DEPARTURES
The snow continues its recent decline especially in the sun.
The very low expected snow does not alter the snowpack stability. However, the winds expected in the night to train with the recent snow, some new accumulations and superficial slabs especially in the high mountains, but also notably lower at the edge of Piedmont and on the tops of the Bauges.
Other slabs more or less trained hard recently by the strong wind of Northwest remain mostly above 1800/2200 m. The attrition of smal hard surface slabs are still reported today in the hills south-2200 m. Others have been triggered artificially wide variety of exhibits.

The accidental risk therefore remains marked, especially over 1800/2200 m depending on the mass. A small surcharge as the passage of a single skier can be enough to trigger a surface slab more or less harsh, especially in the low slopes suffering the effect of solar radiation but also in other exhibitions as East to South-East to 'sheltered from the wind. A higher surcharge as the passage of several skiers or snowboarders or raquettistes can trigger a slab avalanche more or less thick mobilizing sometimes a fairly large amount of snow.

Some natural attrition will occur through the night wind and then the sun and softness in the day. Some superficial casts and sometimes snow avalanches more or less recent wet or brittle slabs will occur just all altitudes during the day but mostly below 2500 m in exposed sunny slopes to the east and then to the South, then to the West. We can not exclude an avalanche substantive steep grassy or rocky slabs. A surcharge greater or lesser degree can promote their outbreak.

WEATHER HIGHLIGHTS:
Beautiful light subjected to a good night and day with fresh high clouds in the afternoon.

Isothermal 0 ° C up to 1400 and 2200 meters.
Wind at 3000 m: dominant northwest 30 km/h.

SNOW CONDITIONS:
They are again excellent. The thickness of snow on the ground ranges from 30 to 100 cm at 1500 m and 140 cm in the Bauges and Beaufortain. A 2000 m it reaches 80 to 200 cm. The soil is bleached from 800 meters and can skier since 1000 to 1400 meters.
The snow surface is a little crusty below 2300 m in sunny slope. It is sometimes blown aloft, especially in the Haute Maurienne.

STABILITY OF SNOW COVER:
RARE SLABS AT ALTITUDE BUT NATURAL DEPARTURES

The recent snow fell since Sunday (20 to 50 cm) cup fairly quickly and improve its cohesion. In the high mountains, however, this improvement is a little slower beneath 2200 2500 m. Slabs formed by the wind northwest persist locally, often covered with a little snow most recent generally little windy.
Some patches may still be sensitive to surcharges. Caution remains rigorous off-piste especially above 2200 m to 2500, particularly in exhibitions in North East and South-East.
The redoux and the sun will be aggravating factors, weakening the anchorages snowpack. Slabs can even be detached naturally during the day, from early morning to East and South-East, a little later in the South and West.
Some small avalanches and casting surface of wet snow will also start spontaneously at altitudes more modest during sunny periods. But some areas between 1500 and 2000 meters are covered with snow and avalanches can result in a locally volume of snow Therefore,

ESTIMATE OF RISK UNTIL WEDNESDAY EVENING:

WEATHER OVERVIEW UNTIL WEDNESDAY EVENING:
Alternating between cloudy passages (few flakes), and with light moments of sunshine during the day. New cloud degradation Wednesday evening.

Isothermal 0 ° C on the rise between 1000 and 1500 meters.
Wind at 3000 m: NORTHWEST 50 km / h and then WEST-SOUTHWEST 10 to 30 km/h.

SNOW CONDITIONS:
They are excellent again as in the heart of winter with a bleached soil from 300/500 meters and a "skiabilité" from 1000 meters. The thickness approaching 80 to 120 cm at 1200/1500 meters and reaching 140 to 200 cm meters near 2000m locally over 270 cm as Beaufortain or above 2500 meters.
The snow surface is still light and cold (humidification possible only above 1000/1500 meters), or as nearly blown ridges with accumulations.

STABILITY OF SNOW COVER:
MANY SLABS AND SOME NATURAL DEPARTURES

5 to 25 cm of snow fell since 1200 meters with the disruption of Monday evening is a cumulative 48 hours of 15 to 45 cm.
Nevertheless, the slowdown continues, with special "effective" below 2000 meters. However, the winds of Northwest currently has fostered the development of slabs and those from west to south-west provided will doubtless form new, generally above 1600/1800 meters in 2000 and Bauges / 2200 meters on the other mountain.

So we will return to superficial instability marked on most of our reliefs with 20 to 50 cm of snow often windy on the sub-strata still backward and sometimes fragile (recognizable particles, snow rolled, etc.). The risk of rupture when overloaded even by a single skier continues to be important, particularly with exposure of South-North and sometimes Northwest. Please note that these triggers caused, in the form of slabs more or less friable, very locally can expand (warp exceeding 70 cm and important vertical). It has been reported every day at least one accidental departure above 2000 to 2500 meters, great caution is therefore required in off-piste.

In addition, we can expect further attrition, particularly with clearing. They are limited to frequent but also cast a few small to medium avalanches although a more important is not completely ruled out.

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:
