Up to two more metres of snow is forecast for Europe, only adding to the mountains of fresh powder caving in roofs, cutting off towns, causing  traffic gridlock and triggering deadly avalanches.

The massive storm has claimed 21 lives across Europe in the past 10 days, including that of a Sydney teenager who was buried under two metres of snow after an avalanche in Austria.

The school sent an email to parents saying Max Meyer’s (pictured) life had been “tragically cut short”.

The family issued an emergency call for help after being unable to get down the mountain trapped in deep snow. An avalanche hit them while waiting for rescuers to arrive, burying the mother and her teenage son, Max Meyer.

Police said the boy’s mother freed herself and was uninjured but her son was “completely buried and trapped for 20 minutes, according to the ABC. He could not be revived.

And now, Europe is bracing itself for more, with a fresh system sweeping south from the North Sea, across France and moving into the alpine regions of Europe with “significant” amounts of snow.

Snowfalls are forecast even for parts of Greece and Turkey in coming days.

“There are still a number of active weather systems in a number of these locations, with more significant weather to come into the heart of Europe over the next 48 hours or so,” BBC weather forecaster Philip Avery said on Saturday.

A seven-year-old child was killed by a falling tree weighed down by snow in Aying, near Munich, and further concerns about snow forced the cancellation of 120 flights at Frankfurt airport and 90 flights at Munich airport, German news agency DPA reported.

Six German teenagers are lucky to be alive after emerging from an avalanche that engulfed them at the Wildkogel resort in Austria’s Salzburg province.

In Salzburg, all parks, public gardens, play areas and cemeteries were closed on Friday because of the danger of trees falling under the weight of snow.

Jet fighter disappears during Swiss border snowstorm

Meanwhile, French military authorities have said a pilot and a navigator were killed when a fighter jet disappeared during a training flight while flying in a snowstorm near the Swiss border.

More than 100 rescuers, police officers and others searched icy mountains for the Mirage 2000D and the two-person crew after it disappeared from radar on Wednesday local time.

The French air force said on Thursday night that the pair had died and identified them as Captain Baptiste Chirie, a combat pilot with 24 war missions and Lieutenant Audrey Michelon, an arms systems navigator who participated in 97 war missions.

The air force did not detail the cause of the accident.
