Avoriaz and Tignes are posting the snow lying 3m (10 feet) deep on the highest slopes this morning, the deepest reported in two months.
The increased snow depth follows the first part of a major storm, which has seen resorts report up to 60cm (2 feet) of fresh snowfall in the past 48 hours, with much more to follow over the weekend.
The most intense snowfall is forecast over the north-western Alps of France, Italy and Switzerland with up to a metre more expected on higher slopes over the coming 48 hours. Most other parts of the Alps should see significant snowfall, but not quite so much.
The snowfall is arriving with strong wind gusts and higher lifts at many French areas are reportedly currently closed as a safety precaution.
Avalanche danger has also been raised to level 3 ("considerable") so far across a wide area and may rise further.
Unfortunately rain has been reported at some lower resorts and valley slopes with the snowline varying between about 1200m and 1800m. Zermatt at 1600m, reported 5cm of snowfall at resort level this morning but lower resorts like Kitzbuhel have reported rain in valleys.
