UPDATE 9:00 a.m.:
Five survivors are being pulled from the snow, according to the Republican Company for Alps Security.
An avalanche at a French ski resort killed at least four people on Monday, and five are still missing.
The group of nine people at a ski resort in Tignes were swept away from the resort's designated ski areas at an altitude of roughly 6,900 feet.
"Five people are still buried under a huge mass of snow," a rescue official said.
This is the worst avalanche since France's ski season began, the BBC reported.
Here's another look from a witness.
The victims' nationalities are not yet clear.
