Snow!

What I CAN tell you though is that it's still dumping with snow at 2100m even though the air temperature appears to be 3 degrees. It's melting on the road, but it's settling on the other snow. Apparently it's raining in Les Boisses (1800m). The temperature is due to drop again this afternoon and I expect the roads will get covered again. Meteo Bourg are forecasting up to 60cm tonight which is frankly unbelievable. Matt |

I hope at least some stays until Easter. |

With more forecast into next week! * - zero isotherm's going to be around 1400-1800M in the Savoie, so choose wisely... Um, what does this last bit mean? Below that height the snow will be melting. Or: Below that line the snow will be... rain :-( Not strictly speaking. The rain/snow limit is often quite diffreent from the zero-degree mark. Usually much lower, so one can still get significant accumulation of snow very much lower than the 0 degree line. It is not even a fixed or necessarily positive difference. I have seen snow at 4 degrees (let's ignore hail in the summer), whhich normally is a 600m difference. Nauturally it tends not to last once the storm has passed. Proof of our old friend the Wind-Chill Factor having its effect? First time I went to Tremblant (Quebec) the mountain-top temp was -25C, to which they had to factor in a further wind-chill of -20C. As a result of which I can tell you that -45C feels a bit nippy... Indeed, been there, done that, etc. Between the wind and the cold, I've seen myself having to use my poles to get started on McCulloch and Kandahar |

I think there's a lot of fun to be had over the next fortnight, as long as the wind doesn't blow all the powder into Italy. Matt * - zero isotherm's going to be around 1400-1800M in the Savoie, so choose wisely... Well, heck - I was taking the forecast with a pinch of salt, but the last 60 hours have brought maybe another 50cm, possibly more. It was still a bit cloudy at 9am which seemed to keep some people in doors, so we had an hour of deserted pistes and powder everywhere. Then the sun came out and so did the crowds, but it still doesn't feel very busy - not much in the way of lift queues. Best conditions of the season here so far I'd say, and all the forecasters seem to be agreeing for once that Thu/Fri/Sat will bring another 50 to 70 cms coinciding with a big drop in temperature (freezing at sea-level). Whoop! Matt |

I'd guess at an average level of 50cm new snow in Engelberg over the last three days too. That's on top of the new stuff that had fallen earlier last week, so in sheltered areas there really is a metre or more of fresh snow. At times on Sunday it was difficult to breathe through the snow. Oddly the official reports often show much less new snow than I've personally seen, but they seem to be taken at village level, 1000m, which is pretty irrelevant to what's fallen between 1800m and 3000m, where most of the skiing is. When I left the hill yesterday afternoon around three it was snowing heavily as low as 1200m, with heavy rain at the village level and all the way back to Basel later on. It was still a bit cloudy at 9am which seemed to keep some people in doors, so we had an hour of deserted pistes and powder everywhere. Then the sun came out and so did the crowds, but it still doesn't feel very busy - not much in the way of lift queues. Best skiing of my (long) weekend was probably on Sunday, when poor visibility kept the day trippers away, but we got lucky and skiied in the clear bits, with the poorer visibility mostly when we were having lunch. Started the day with a run down the Laub, which had been good, then even better, the two times we'd done it the day before. Even our high expectations were exceeded, with deep soft powder for much of its 1200m drop, and only a half-dozen sets of tracks (despite our 0930 start) spread out across the mountain. Tree-skiing (well between the bushes really) towards the bottom made the most of the snow down there, again cutting fresh tracks in new snow, with very little in the way of sun- or wind-affected crustiness. Later we did more in the Jochpass area and down to Engstlialp, which was equally nice. Best conditions of the season here so far I'd say, and all the forecasters seem to be agreeing for once that Thu/Fri/Sat will bring another 50 to 70 cms coinciding with a big drop in temperature (freezing at sea-level). Whoop! More forecast for Engelberg too, which is good as we've got a group of friends coming over for the whole of next week. Freezing levels of ~700m should keep all the new stuff in great nick, we hope. |

We have friends out in Les Arcs at the moment and they are reporting the best skiing of their lives. The forecast for the next few days looks bad (we are driving down over night this evening). I will double check the snow chains! From what I hear I may have to swap my ice skis (actually racing skis) for a pair of soft things. John |

Whoop! Matt It just gets better and better. They were right about the new snow - it's fully dumping outside and due to get heavier as the day and night go on. How I'm going to get my parents to the Eurostar tomorrow morning is anyone's guess. Chains, 4x4, an early start and a bit of luck I expect. As for conditions this week, I think the quote from 'Chippie' (Tignes legend and recent 'star' of the new Ski Sunday) says it all - "That's as good as it gets." Me thinks that if it's sunny at all next week, he may have to revise that statement. Matt |
