Terror police are on standby in the Alps
The anti-terror operation swung into action as part of Operation Sentinel which sees armed officers patrolling airports.
But it was extended amid fears that ISIS madmen want to blow up people in local bars and restaurants during their skiing holidays.
Terror expert Will Geddes who runs the International Corporate Protection Agency said: “The military and police presence has been flooded right across France.”
He added they were particularly concerned about any location where there is a “large group of international visitors gathered”.
“There is a real risk of a terror attack being a double threat with avalanches,” Mr Geddes added.
Ski resorts have stepped up security amid fears that jihadis are keeping watch, ready to strike, according to the Daily Star on Sunday.

Eyewitnesses said security personel at bar 360 in Val Thorens beefed up security and searched patrons’ backpacks for weapons.
Armed police with machine guns have also been seen patrolling Chambery Airport in France, which is located close to the Alpine resorts.
It comes after intelligence sources suggest an attack on the slopes could be deadly as just a gunshot could trigger an avalanche.

Security officials fear a lone wolf attacker could cost many lives and the anti-terror police want to prevent a tragedy before it happens.
Over one million British holidaymakers travelled to ski resorts last year, figures showed.
France is on high alert in the wake of a series of terror attacks – including the Bastille Day killings in Nice by terrorist Mohamed Lahouaiej-Bouhel last year.
And the Paris attacks in November 2015, which left 130 dead (89 at the Bataclan theatre) and 368 people injured.
