The climbers, who had dug a snow hole, had been in touch with the rescue services in Chamonix via mobile phone, but the rescuers was unable to reach them due to poor weather and high winds.
One of the climbers reported that his partner had died on Friday.
A brief lull in the weather on Sunday allowed a helicopter to pass near to the route and the rescue team sighted the second climber outside of the snow hole and hanging on a rope. They were unable to reach the couloir but were convinced that both climbers had passed away.
The rescue services will attempt to retrieve the bodies when the weather clears.
