Many more people still believed trapped in snow in the Himalayas in central Nepal, officials say.
Trekkers were trapped in “freak” heavy snowfall as they returned from the Thorung La mountain pass on the Annapurna Circuit, in Mustang district.
Meanwhile five more climbers are presumed dead after an avalanche in nearby Manang district.
Rescue officials said the death toll could rise as dozens of other foreigners and locals who had been trekking were out of contact and could have been caught in blizzards.
Authorities are still trying to make contact with at least 100 other hikers who were thought to be in the area.
Of those killed in the Annapurna region, only four bodies have so far been recovered, of two Poles, an Israeli and a Nepali.
“There has been heavy snowfall in the area, up to three feet (91 cm),” police official Ganesh Rai said.
BBC South Asia Editor Charles Haviland says it is one the deadliest spells of bad weather ever seen in the region.
Thousands of trekkers visit the region at this time of year when weather conditions are usually favourable for hiking trips.
Nepal’s tourism industry is still recovering from the aftershocks of an ice avalanche that struck the lower reaches of Mount Everest in April, killing 16 sherpa guides in the worst disaster in the history of the world’s highest peak.
More than a tenth of the nearly 800,000 tourists who visited Nepal in 2013 went hiking or mountain climbing, providing a key revenue stream for the aid-dependent nation.
