One person was evacuated to a hospital in Grenoble, France, in "extremely serious condition," according to the official, who spoke on behalf of Hautes-Alpes prosecutor Raphael Balland.
The avalanche happened around 3 p.m. (9 a.m. ET) around France's Ecrins National Park
near the village of Pelvoux, which is about 40 kilometers (25 miles) west of the Italian border and 120 kilometers north of where Germanwings Flight 9525 went down last week.
It struck a group of about 10 hikers and a guide, the prosecutor's office said.
A large-scale search is underway for those still missing.
The search party includes at least 27 police officers and dogs out of Briancon, Isere and Modane and 30 firefighters, according to the official in the prosecutor's office in Hautes-Alpes province. Four helicopters flew over the scene as well.
Weather forecasts called for temperatures around or below freezing Wednesday night.
