avalanche

Yesterday morning, on the Posettes section of the Vallorcine Balme ski area, a group of four skiers was surprised by a snow slide.
A 43 year old skier was caught in the avalanche. He was dragged down the slope over a hundred meters and then jumped a cliff.

Yesterday afternoon, at the intervention of the PGHM Chamonix, the man, Swedish nationality, suffered a pneumothorax and a broken back.
The man was transported by helicopter to Sallanches, then transferred to Grenoble.

A videographer at an unsanctioned snowboard freeride event captured some provocative footage last weekend of an avalanche airbag in action:

They say a picture is worth a thousand words. In this case, a one-minute video is worth nearly 250,000 views on Youtube. At an unsanctioned snowboard freeride contest in Colorado, competitor Meesh Hytner, was captured in a class 3 avalanche. She deployed her Backcoutnry Access (BCA) Float 30 avalanche airbag and remained on the surface for the duration of the slide, escaping with no injuries.

Videographer Tyler Malay was filming at the grassroots event, called the Coloradikal Backyard BBQ, and captured the entire incident. The resulting Youtube video has gone viral, gathering nearly 250,000 views as of Friday (Feb. 3).

BCA’s Float airbags have been available in North America for three years, but only recently have been approved for sale in Europe. The company introduced two new models at ISPO earlier this week: the Float 22 and the Float 32. For more info, see http://www.backcountryaccess.com/airbag .

A 54 year old piste patroller has been killed in Klosters during avalanche control work. The patroller and his colleague had loaded an avalancheur with an 8.3cm rocket. The patroller was in the process of removing 2 safety devices when the charge exploded without warning. Standing behind the device the patroller was killed by the recoil and by shrapnel from the charge. The accident follows a similar incident on the 18th December at Flégère in the Haute-Savoie. The charge exploded inside the launcher injuring two piste patrollers.

(Written Sunday, February 13)

RISK ASSESSMENT THROUGH MONDAY EVENING:
All massive Haute-Savoie: LOW_RISK (level 1).

WEATHER OUTLOOK UNTIL MONDAY EVENING:
Mostly sunny, becoming cloudy in the afternoon on Aravis and Chablais. Light Foehn in the Mont Blanc, clouds may be required by Italian collars in the interior of the mountain range. Temperatures at 2000 m: -2 to +2 DG.

Isotherm 0 DG: 1800 m.
Wind at 2000m: Southwest 20 and 30/40 km / h, Foehn trend around Mont Blanc.
Wind at 4000 m: South irregular 20 to 50 km / h.

SNOW_CONDITIONS:
The snow is very low for a mid-February. In North Slope at 1500 m: only 15 to 30 cm of snow. In southern slope, we must go beyond 1700 to 2100 m to find snow. It happens to put on skis or snowshoes around 1200 m lower in the shade and cold but beware pebbles and patches of ice.

Quality of the snow on Monday: often crusty and hard. In northern slopes, we find an extremely compact snow or loose snow zones (powdered sugar) topped with a crust. In southern slopes, the frozen snow in the morning softened up temporarily on the surface to 2400 m. In high-mountain, snow has been worked by the wind often compact, some in bare ice ridges.

STABILITY OF THE SNOWPACK:
Generally well bonded

The last snowfall dates back to January 12. No avalanches were reported last 8 days. The snowpack remains cold in shady slopes, while there is snow Spring adrets.

Risk of spontaneous slides: a few small cast surface at midday in corridors mixed rock / snow or rock bars. Only on steep slopes and very sunny. The snow being reharden afternoon in windward slopes and under the veil of cloud.

Risk of triggering an avalanche of skiers passing: low. Rare isolated patches may persist in the top of Mont Blanc, difficult to break.

Attention to the risk of falling + slip on hard snow (crampons useful even mid_elevations).

TREND FOR TUESDAY:
Risk increased with a small layer of snow expected: the appearance of slabs, small but fragile, especially in the cold slopes.

SNOW_CONDITIONS:
The snow is very low for a mid-February. The deficit in snow in places close to 1 m m 1500/2000 In North Slope at 1500 m: only 15 to 30 cm of snow. In southern slope, we must go beyond 1700 to 2100 m depending on the steepness of the slope to find snow. It happens to put on skis or snowshoes to 1100 to 1200 m lower in the shade and cold but beware pebbles and patches of ice.

Snow quality: often hard or caked with areas of old-type powdered sugar on the surface or beneath the crust. With the sun in the sunny slopes of mid_elevations, hard snow in the morning get damp during the day until around 2500/2700 m south slope. In high-mountain, the snow is often worked by the wind with snow still dusty areas.

STABILITY OF THE SNOWPACK:
With a calm day last month, the snowpack is well bonded now.

The low risk of avalanches Sunday summarize a few surface flows in wet snow in a steep slope more or less south warmed by the sun in the afternoon, where there is enough snow course. These possible avalanches will be small.
As for the risk to a skier could trigger a slab avalanche in dry snow, it could possibly be present only in high_elevations the Mont Blanc. These possible slabs formed by the wind will be rare.

EVOLUTION OF THE AVALANCHE RISK:
Stationary for Monday.

RISK ASSESSMENT THROUGH MONDAY EVENING:
All ranges of Haute-Savoie: Risk 2 (limited)

WEATHER OUTLOOK UNTIL MONDAY EVENING:
Starry Night, but little or refreezing of snow slopes mid_elevations, minimum temperatures in the slopes around 1500 m 8 dg,
Big beautiful Monday, very soft in the sun mid_elevations. In high_elevations, unn little windy atmosphere, the temperature at the Aiguille du Midi -7/-5 dg.

Isotherm 0 DG: 3300/3100 m. Isotherm -10 DG: 4500 m.
Wind at 2000 m: low on Sunday evening then southwest 20 / 30 km / h.
Wind at 4000m: Northwest 20 early night and 20/40 km / h.
Mt Blanc summit: West 30/50 km / h.

SNOW_CONDITIONS:
The snow is very low for early February. In North Slope at 1500 m: only 20 to 30 cm of snow. In southern slope, we must go beyond 1600 to 2000 m depending on the steepness of the slope to find snow. It happens to put on skis or snowshoes around 1200 m lower in shady and cool but watch out for rocks. Caution on the lower parts of the glaciers with snow bridges over crevasses sometimes fragile.
Snow quality: often crusty and hard with few areas of old-type powdered sugar on the surface or beneath the crust. With the sun in the southwestern slopes to the west until about 3000/3500 m, hard snow (crampons recommended steep in parts) gets wet.
In high-mountain snow has recently been heavily worked by the wind.

STABILITY OF THE SNOWPACK:
risk localized wet snow slides, slabs high_elevations.
For over twenty days with almost no snowfall, the snowpack is generally well bonded.
With the softness marked the day, a few wet snow slides may occur in the corridors and steep slopes. Either by attrition or triggered by hikers and downhill. Therefore caution in steep passages on wet snow.
The departure of a bottom plate is also possible (any time).
In high_elevations, the risk of triggering an avalanche is limited, rare presence of wind slabs formed by the blast last Wednesday at high altitudes, which may break under the weight of the skier (s) / climber (s).

EVOLUTION OF THE AVALANCHE RISK:
Little changed on Tuesday and Wednesday, the risk of wind slab will decrease high_elevations and we will keep a small risk of wet snow avalanches.

Mont Blanc mountain range above 3000 m: limited risk (level 2).

WEATHER OUTLOOK THROUGH SUNDAY EVENING:
Always the beautiful sunny weather, with a big thaw during the day.

Isotherm 0 DG: 2800 m and 3300 m.
Isotherm -10 DG: around 4500 m.
Wind at 2000 m: low.
Wind at 4000m: Northwest, 40 and 30 km / h.

SNOW_CONDITIONS:
The snow is very low for early February. In North Slope at 1500 m: only 20 to 30 cm of snow. In southern slope, we must go beyond 1600 to 2000 m depending on the steepness of the slope to find snow. It happens to put on skis or snowshoes around 1200 m lower in shady and cool but watch out for rocks.

Quality of snow for Sunday: often crusty and hard with areas of old-type powdered sugar on the surface or beneath the crust of frost. With the thaw in the hills south-east to south-west or west, up to 3000/3500 m, the snow becomes wet and soften the surface in the afternoon (spring snow conditions). In high-mountain snow has recently been heavily worked by winds from the northeast.

STABILITY OF THE SNOWPACK:
Risk limited high_elevations well as isolated patches, and a few small streams and wet snow avalanches in the southern slopes in the afternoon until around 3000/3500 m.

For over twenty days with almost no snowfall, the snowpack is generally well bonded.
In high_elevations, the avalanche risk will be limited Sunday with few wind slabs formed by the blast last Wednesday at high altitudes, which may break under the weight of the skier (s).
In addition, given the mild weather during the day Sunday, we can also observe a few small natural avalanches cast or surface in the steep slopes south-east, south and southwest to 3000/3500 m. These flows, few will be likely to trigger more naturally in the afternoon, once the crust has disappeared and refreezing snow moistened by the sun.

Attention also to the risk of slipping in the areas very hard snow and ice.

EVOLUTION OF THE AVALANCHE RISK:
Little change for Monday / Tuesday / Wednesday next, the risk of wind slab will decrease high_elevations and we will keep a small risk of wet snow avalanches every afternoon in the hills south-west is not served until high_elevations .

SNOW_CONDITIONS:
The snow is very low to the heart of winter. In North Slope at 1500 m: only 20 to 30 cm very hard. In the South, we must go beyond 1600 to 2000 m depending on the steepness of the slope to find snow.
It happens to fit the lowest around 1200 m in the shady and cool.

Quality of snow for Saturday: often crusty and hard with areas of old-type powdered sugar on the surface or beneath the crust of frost. With the thaw in the southern slopes more or less, up to 3000 m, the snow becomes wet and soft surface in the afternoon. In high-mountain snow was heavily worked by the wind from the northeast.

STABILITY OF THE SNOWPACK:
Risk well high_elevations limited and the southern slopes of mid_elevations.

With this time desperately quiet for more than twenty days, the snowpack is generally well bonded.
The avalanche risk is limited to rare Saturday windslabs in high_elevations formed by the blast last Wednesday.
With the mild weather during the day Saturday, we can also observe a few small natural avalanches cast or surface in the steep slopes south-east, south and southwest up to 2800 meters. These flows will be low once the crust has disappeared and refreezing snow moistened by the sun, rather then in the afternoon.

Attention also to the risk of slipping in the areas very hard snow and ice.

EVOLUTION OF THE AVALANCHE RISK:
Little change for Sunday and the following days, the risk of slab high_elevations wind will decrease and we will keep a small risk of wet snow avalanches in the southern slopes of mid_elevations afternoon.

Mont Blanc:
- Higher than 3000 m: limited risk (level 2).
- Lower than 3000 m: LOW_RISK (level 1).
Aravis and Chablais: LOW_RISK (level 1).

WEATHER OUTLOOK UNTIL FRIDAY EVENING:
A few clouds to 1500/2000 m the morning, especially on Aravis / Chablais. Then sun dominant barely veiled. Temperature at 2000 m: -4, then a CEO.

Isotherm 0 DG: 1500 and 2000 m.
Isotherm -10 DG: 3800 m.
Wind at 2000 m: West 10 km / h.
Wind at 4000m: Northwest 40, then 60 km / h.

SNOW_CONDITIONS:
The snow is very low for early February. In North Slope at 1500 m: 20-30 cm in total. In the South, should exceed 1600 m to find a snow acceptable, or even 2000 m in steep slopes. We can put on skis and snowshoes between 1200 and 1700 m depending on orientation.

Quality of the snow on Friday: generally hard or crusty. Some cold slopes remain snow old furniture, crusty irregularly. Slight softening in the South on Friday afternoon up to 2000 m. In high-mountain snow was heavily worked by the wind from the northeast.

STABILITY OF THE SNOWPACK:
Few wind slabs formed high_elevations Wednesday.

No avalanches were reported over the past 15 days.

Risk of triggering an avalanche: the strong Bise Wednesday brought a few slab in the high mountains. They are generally fragile and not very thick but enough to unbalance a skier. Please note, if you fall steeply, it is difficult to stop on this very hard snow.
On the other hand, in North Eastern slopes, buried the old slab are now very rare and quite solid.

Probability of slides or avalanches: very low.

Finally, attention also at risk of slipping in the areas in very hard snow and ice.

TREND FOR THE WEEKEND:
Risk in a stationary spring atmosphere.

- Lower than 3000 m: LOW_RISK (level 1).
Aravis and Chablais: LOW_RISK (level 1).

WEATHER OUTLOOK THROUGH THURSDAY EVENING:
Beautiful weather veiling then covering the second part of the afternoon.

Isotherm 0 DG: 1800 m.
Wind at 2000 m: North-East 30, then 20 km / h.
Wind at 4000m: Northwest 40, then northwest 20 km / h.

SNOW_CONDITIONS:
The snow is very low for early February. In northern slopes at 1500 m, there are only 20 to 30 cm in total. In the south, must exceed 1600 m to find a snow acceptable, or even 2000 m in steep slopes. We can put on skis and snowshoes between 1200 and 1700 m depending on orientation.

Quality of snow for Thursday: It is generally hard and crusty in places an “old” powder. In south orientation, moisten a little snow in the sun at midday, especially on steep slopes.

STABILITY OF THE SNOWPACK:
Few wind slabs formed high_elevations Wednesday.

No avalanches were reported over the past 15 days.

Risk of triggering an avalanche can still be wary in cold slopes, mainly in the high mountains where the strong wind has probably formed a few slabs on Wednesday. These new slab high_elevations can be triggered by the passage of one person but are generally small. Moreover, very few slab are rather sensitive to large overloads (from several hikers grouped).

Probability of slides or avalanches: very low.

Finally, attention also at risk of slipping in the areas in very hard snow and ice.

EVOLUTION OF THE AVALANCHE RISK:
Friday, Saturday and Sunday will be slightly lower risk.
