Snow!
Lots of it! With more forecast into next week!
Anyone holding off for that last minute deal - go book it now *. 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... |

Um, what does this last bit mean? Below that height the snow will be melting. How do you think La Plagne will be next week? Should be fine, based on that. |

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. |

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. |

Wind chill is the ability of moving air to remove heat from a cooler body. If the air temp is above freezing the snow will melt and the stronger the wind the faster it will melt. The snow below the zero isotherm is because it was formed above that height and has not melted before reaching the ground. The greater the intensity of snow (due to the latent heat of thawing, requiring more heat to melt the greater volume of snow as it falls) and colder the clouds, the lower the snow level will be. |
