The last few days, however, have seen heavy snowfall, and this - combined with strong winds - has resulted in avalanches in Colorado, USA, and in the Alps.
What locals described as a "massive avalanche" and one of the biggest avalanches they'd seen, pushed two cars off a mountain pass in the US state of Colorado and buried them with their occupants inside. Fortunately, all of them were rescued. Click on the picture for the story from CNN.
The story from the Alps is less happy - at least eight people, including two experienced French skiers, have been killed in a series of avalanches. The picture below, showing rescuers in the resort of Val d'Isere, will take you to the BBC news coverage.
