Less Snow?Probably true, BUT I find that the reporting seems more accurate here at Les Arcs than my experience in the States.
Quite a few times here, I thought they got more snow (at least in spots) than they reported. This is in contrast to Tahoe where you often see reports like 48'' to 60'' (inches) or even 72''-96'' after a huge storm- yes they got dumped on, but I could never seem to find the snow drift that they did the measurement.
The fact that these often round off to even feet (4 to 6 & 6 to 8) made me suspect that someone just made a guess at how deep the deepest snow drift was.
Snow also tends to be a bit denser here than say Utah, so a foot (30 cm) here may pack down to the same amount as 2 feet (60 cm) of Utah powder. With that said, I was skiing some very light powder yesterday morning (but which skied much more like Sierra cement today after the wind had a chance to work on it).
Bottom line is it is a great chance for you to broaden your horizons and experience some fantastic skiing even if certain aspects (like the amount of light powder) don't compare to epic days in the States.
