A five-member South Korean expedition team and four Nepali guides were at the base camp of Mount Gurja when the storm struck, police said on Saturday, BBC wrote.
A rescue helicopter at the scene confirmed seeing eight bodies in the ruins of the camp, but was unable to stay due to bad weather conditions.
The ninth climber has yet to be found but is feared dead.
"Five South Korean climbers are dead, three Nepalese nationals are also dead. One Nepali guide is missing," the police spokesman, Sailesh Thapa, told the BBC.
Local media report that South Korean climber Kim Chang-ho, the fastest person to summit the world's 14 highest mountains without using supplemental oxygen, is among the dead.
"The camp was completely destroyed," the BBC heard from a Myagdi District official, Liladhar Adhikari.
"[A recovery team] could see the bodies of the climbers scattered near the camp."
He said another recovery team would be sent on Sunday, weather conditions permitting.
Expedition organizers raised the alarm after losing contact with the group, which set off on October 7, for nearly 24 hours.
The climbers had been waiting for a window of good weather so they could reach the summit, when the storm hit on Friday.
The base camp, which is at least one-day's trek from the nearest village, is at 3,500 meters (11,483 feet), on the 7,193-meter-high mountain.
The rarely-climbed Mount Gurja sits in Nepal's Annapurna region, next to avalanche-prone Dhaulagiri, the world's seventh highest mountain.
According to the Himalayan Database, no one has stood on Gurja's summit since 1996.
Only 30 people have successfully climbed to its peak compared with more the than 8,000 people who have reached the summit of the world's highest mountain, Everest.
