Off-Piste snow report for December 13, 2019 for the Northern French alps – Henry’s Avalanche Talk

Lots of snow falling now, but warmer temperatures for the week ahead
Big snow has started falling. This will set us up for the season, but it will bring high avalanche danger too.

It has been a great week for off-piste skiing, with regular top-ups of 10 to 20 cm fresh snow virtually every other day. Weather alternated between flat light conditions and snowfall one day and clear blue skies with fantastic powder the next.

On Tuesday there was a blue-sky powder day and there were a few avalanches triggered by skiers. This is evidence that the greatest risks are wind slab on leeward slopes.

Current situation in the Northern French Alps:

At the time of writing (13th Dec) the avalanche risk is 4/5 (High). Over the week covered in this extended forecast, however, the danger rating will stay high or at least considerable (3/5). A huge amount of snowfall is expected in the N French Alps and surrounding area. Will we get a 5/5? That would be unusual.

The outlook is unsettled. The first storm will bring cold weather, but then it will warm up across the N French Alps. It will be coldest on the French /Italian border. But 0C could rise to 2700m. This will humidify the snow lower down and damage the quality of the powder.

The biggest storm is forecast for Friday/Saturday, when we may receive a metre of fresh snow in cold weather.

This fresh snowfall will be accompanied by high winds, causing accumulations of snow through drifting. This process is known as ‘wind loading’.

Areas of risk to look out for:

The snow accumulations will make the risk of accidental avalanches, i.e. those triggered by people, very high.
The best advice during this time is to stay on and around slopes of less than 30° steepness.

The areas at greatest risk are wind loaded slopes so E and NE look the most dangerous. However, the bulletin is highlighting high risk (danger rating 4) on all slopes due to the considerable snowfall.

The dangerous slopes will become evident during and after the snowstorms that are predicted. This will be indicated in the daily avalanche bulletins. Also look out for recent avalanche activity, which is likely to be on those leeward slopes that have been loaded with snow drifting by the wind.

Due to the wind during the storms, the biggest danger will be on slopes where the snow has drifted in and built up. These slopes are generally on leeward sides of the mountain and other areas that are sheltered from the wind. This is where you are more prone to trigger a slab avalanche. Be careful because it’s more tempting to ski in these places because there’s more snow!

The danger is increased dramatically if there are ‘terrain traps’ below. In fact, the clearest answer to where there is the biggest risk is on slopes above dangerous terrain – features like cliffs, trees, holes and narrow valley bottoms.

This will be indicated in the daily avalanche bulletins. Also look out for recent avalanche activity, which is likely to be on those leeward slopes that have been loaded with snow drifting by the wind.
