Snow report April 18

Snow report April 18, 2008

Last week I said that our experience off-piste has been, “great despite totally unpredictable weather and days that you would think aren’t going to be good.. but then they turn out to be great!” This trend of passing storms then sun, then passing storms then sun…. has continued over the last week and will continue this coming week too – but with warmer temperatures forecasted at least over the weekend. The weather pattern that has brought us ‘winter in spring’ since the first week of March has provided us with some of the most phenomenal skiing I’ve ever experienced here in the French Alps. For me, reporting from the higher Alpine resorts where the skiing is mostly above 2000 metres, the best skiing has been almost exclusively ‘winter snow skiing’ (on snow that has not been through melting & freezing cycles). Last week was again characterized mainly by winter conditions - although when the sun comes out, you feel it’s spring (well it is mid-April after all!). As a result of the strong solar radiation that is often been present even when cloudy, we have been going ‘high and north’ to take advantage of the cooler, shaded areas where the snow gets the least amount of incoming solar radiation/heat. See photos of touring and skiing this past week on www.henrysavalanchetalk.com > Free Stuff > Photo Albums > Skiing with HAT (www.hat.skioffpiste.co.uk/photos/hatskiing/index.html ). The trick still seems to be getting out early (despite wind, bad visibility etc.), going as high as possible (above 2500 metres) and looking for slopes that are sheltered from the wind [winds seem to have been coming out of the Southwest to East in much of the Northern French Alps and this is supposed to continue well into the week of April 21]. Below 2500 metres there has been quite q bit of melting and freezing (spring snow) which is pretty nice if it is smooth but awful where there are old frozen tracks, frozen avalanche debris or if the melt-freeze crust is not thick enough to hold your weight (breakable curst is not nice)!

Snowpack Quality & Stability

It looks like the successive storms and clearing will continue with a significant increases in temperatures, especially from 18-20 April, which means we have to watch out for big wet snow avalanches on slopes that are going to get the sun, are at lower altitudes and therefore are going to subject to rapid warming (I’ve already heard of a number of avalanches coming down onto pistes that were closed due to avalanche danger). For Sunday to Wednesday, the rain snow limit is forecast to stay around 2000 metres which is not all that high for this time of year, and that means more great skiing!

Otherwise, the light/moderate snowfalls and wind have continued to form surface slabs, mostly above 2500/2700 m. The wind, the sun, warming and precipitation will encourage some instability and avalanche activity on sufficiently steep slopes, a little at all altitudes. Below 2500/2700 a relatively small surface slab may turn into a larger wet snow avalanches; above that, they could lead to bigger slab avalanches too in the form of dry/cold snow slabs. The risk of these types of slabs is most prevalent on Northeast to Northwest facing slopes (the ones that we are skiing on most). So I will be especially careful if we get 20 cm or more in one storm - or in a short amount of time like 48 hours, especially if there is a good amount of wind, which can lead to twice the amount of snow that came out of the sky on these sheltered slopes (again these are the slopes that will have the best skiing). I’ll be limiting the risk mainly be avoiding steep slopes that have cliffs and/or narrow valley bottoms below them. A person was killed on the 15th due to a relatively small avalanche that took him over some cliffs: see www.pistehors.com

Tip of the week:
I’ve been long-winded enough this week; so I’ll leave it to you to…. ‘Ride Hard ! Ride Safe’

Henry & Andreas (HAT & Alpine Experience)

SPECIAL THIS WEEK:
Andreas’s special skiing summary from the Espace Killy (Val d’Isère & Tignes): “We keep getting some fresh snow to work with every other day and just the right amount to cover old tracks and give a new nice base but not so much so that it gets dramatically unstable so that we can’t move around safely. So this has meant great skiing lately with of course respect for new snow and also a lot of attention to timings and following temperatures etc! Our worst days now are when we get days with a few clouds and bad visibility but not any new snow, which means that we can neither ski powder comfortably, nor do we get a good spring snow transformation. So, we are touring a bit at the moment and we had a great mini tour with a night in the Col des Fourshut last weekend, 13-14 April, and despite Henry’s snoring which kept us all awake, we had a great time!!! So let’s hope the conditions stays good until the end and personally with the great base we have now, we should have lots more good skiing until the end of the season.”

PS We’re STILL doing lots of transceiver training at the moment in Val d’Isère: 35 euros for saisonaires for a full afternoon of coaching, timed searches, basic rescue procedures & a waterproof reference card (wow!). Call Jamie on 06 23 05 75 09

Another Great Day

HATadventures course team: Michael, Morten & Soeren. This photo sums it all up (see below for vids). Got 10-15 cm last night, sun today and it's snowing again!!

 

Snowpack Update

What an amazing couple of weeks. Rarely have I seen so much snow and such a stable snowpack at the same time.

The snows that are coming now (end of week of March 24) are supposed to be fairly light, in terms of accumulations and in consistency, throughout the Northern French Alps and surrounding areas.

Current Stability

There have been quite a few accidental slab releases over the last few days (Météo France has reported several each day) most without consequence probably because the slabs have not been all that big and/or the people were able to ride out or weren’t taken too far. I have seen and heard of a few slabs triggered at distances of 10 metres or so on slopes facing North East to East – which makes sense since the winds have been mostly coming out of the West & North West and this will continue through the weekend. The winds aren’t supposed to be as strong for this weekend and that is a relief!

Tip of the week:

Watch out for slab instability (& releases) as a direct result of very recent wind loading on slopes and in general areas that were/are protected from wind in recent storms (these are very often East’ish’ slopes, but not always!!). Some of the very recent slab releases have had fractures at the top (or crown walls) of up to 70 cm. So, despite the exceptional stability of all this new snow, I’m still being very careful as I enter into steep areas of nice smooth fresh white snow.

‘Ride Hard Ride Safe’!

Slabs Triggered from a distance...

there were quite a few slabs triggered from a 10 metre distance observed by colleagues and me today. Also, natural, artificial & other accidental in Savoie & Haute Savoie mainly small for the moment. This slope under the Mt Blanc chair in Val d'Isère is facing North East. The wind has been mostly coming out of the North West (although is supposed to change to South briefly tomorrow then back to North West through West for Thursday on through the weekend). This slab, a direct result of very recent wind loading, exemplifies what is in store for the next few days (and so does the distance triggering). Only I think the instability will grow with the continued wind loading and new snow accumulations. The avalanche activity has been relatively calm over the last 10 days or so, but I think the instability could pick up with all this new snow and wind over the next few days. The slab in this photo and the way it was triggered is telling us something.

snowing again!

in fact it is dumping. 60cm of light snow in the last 12 hours! If you don't believe it, check these vids out (photos coming soon Mike!)

Epic Day

.... with HAT & Dan Egan's X-Team Ski Clinics

Here's Richard True setting a good example as usual. For more photos see 'Skiing with HAT & Ski Clinics' (you may have to scroll down a bit to find the right date on the photos!). For Vids see below

 

Waist Deep!

Skiing with Dan Egan's X-Team Ski Clinics It's been snowing pretty much non stop for two days now. Here's Cathy making a few turns... and disappearing!

It's dumping!

Snowed 25 cm last night and cleared for a good part of the day today. Then it started snowing again this pm. 30-40 cm for tomorrow! I'll try to get some photos and vid but still too busy having fun. This week with Dan Egan and Ski Clinics

Winds coming out of west & n.west some slabs but seemed be holding pretty stable in espace killy today... but tomorrow things will be more unstable tomorrow with the new accumulations. we'll all be alert tomorrow for wind slabs and people cutting slopes above us
