Police official Bir Bahadur Budhamagar said villagers who on Saturday reached the site at the base camp of Mount Gurja, a 7,913 metre-high peak, spotted seven bodies on the mountain slopes.
Five South Korean climbers and four Nepali guides were swept off a cliff by strong winds as they waited for fairer weather before starting their ascent of Mount Gurja, a mountain of 23,599ft in west Nepal.
The helicopter team hopes to return on Sunday, if weather clears up.
Police reports say the storm struck while the group were at their base camp, which was destroyed.
The area lies about 216 km (135 miles) northwest of Nepal's capital, Kathmandu.
The climbers had been waiting for a window of good weather so they could reach the summit, when the storm hit Friday.

De la même manière, limiter le réchauffement à 1,5°C aboutira à ce que l'Arctique ne soit libre des glaces qu'une fois par siècle. Un coût qu'il faut mettre en regard avec le coût, bien plus élevé, de l'inaction, soulignent les scientifiques.
Team leader Kim was the first South Korean national to summit 14 peaks above 8,000 metres without using supplemental oxygen.
Wangchu Sherpa, managing director of Trekking Camp Nepal, who organised the expedition, said they raised the alarm after they had not heard from the team for almost 24 hours.
A police rescue team is now making its way on foot to the site while the helicopter team hopes to return to the camp on Sunday, if weather conditions improve.
According to the Himalayan Database, no-one has stood on Gurja's summit since 1996.
The South Korean team were planning to scale the mountain via a never-climbed route, the Korean Alpine Federation said.
Mount Gurja, also called Gurja Himal, while not famous as one of Nepal's most challenging peaks, is part of the Dhaulagiri range, which is topped by Dhaulagiri I, the seventh-highest mountain in the world.
