After a fourth day of searches, 384 people have been rescued from the Annapurna trail, 216 of them foreigners, in the country's worst-ever trekking disaster.
Helicopters have been searching parts of the trail high as 5,790m (19,000ft) for survivors.
The government said the priority was to rescue 22 stranded hikers.
The trekkers are stranded at Thorung La pass, and face a shortage of food and water. Army helicopters tried to rescue them but failed after being unable to land.
The BBC's Andrew North in Nepal says that it is still unclear which climbers have been accounted for and which are still missing.
The task of the authorities is made more complicated because there are thousands of climbers in Nepal at this time of the year.
Army helicopters tried unsuccessfully to rescue them on Saturday between the Mustang and Dolpa districts, government rescue coordinator Suresh Acharya said.
Twenty bodies have been recovered but 19 bodies are still in the snow and a rescue team will be deployed on Sunday to dig them out and retrieve them by air, he said.
One of the main trekking routes - the Thorung La pass, the high point of the Annapurna Circuit - is now  "relatively safe" after the army cleared snow, he said earlier.
Rescuers have only limited resources and most of the missing and dead are believed to be at the maximum heights that helicopters can reach.
Nepalese, Japanese, Israeli, Canadian, Indian, Slovak, Vietnamese and Polish trekkers are said to be among the dead.
Many survivors have been left with severe frostbite and will have to have limbs amputated.
Nepal earns huge revenues from the tens of thousands of trekkers and climbers who flock to the Himalayas every year.
However, it remains a very poor country and the authorities here have struggled to cope with the scale of this disaster, our correspondent says.
This has been a particularly deadly year for Nepal's trekking and mountaineering industry.
An avalanche on Mount Everest in April killed 16 Sherpa guides and resulted in a significant drop in the number of expeditions to the world's highest peak.
The latest disaster comes at the height of the trekking period.
Nepal blizzards: Survival guide

Philando Castile was shot in his car in St Paul, Minnesota, on Wednesday as he reached for his driving licence, his girlfriend said in a Facebook Live video taken during the aftermath.
His death follows that of Alton Sterling, who was shot dead by police during an incident in Baton Rouge, Louisiana, on Tuesday.
What do we know about the two victims?
The 32-year-old had worked in the canteen of a school in St Paul for more than 10 years, his uncle Clarence told media in Minnesota. The JJ Hill Montessori Magnet School in the city listed Mr Castile as a cafeteria supervisor on its website.
On his Facebook page, Clarence later re-posted comments by a Minnesota bishop, Divar Kemp, calling Philando Castile "an a1 genuine man who was killed because he obeyed what the officer asked him".
Mr Castile's cousin, Antonio Johnson, told the Star Tribune newspaper his cousin had graduated with honours from St Paul Central High School.
Mr Castile was "a black individual driving in Falcon Heights who was immediately criminally profiled and he lost his life over it tonight", he said.
He added that Mr Castile was "very non-confrontational" and "a real upstanding citizen".
The Star Tribune said Mr Castile had only minor offences on his criminal record.
Little is publicly known about Mr Sterling, 37.
The father of five sold CDs and DVDs in the car park in which he died, family members told media in Louisiana.
"If you asked Alton for the shirt off his back, he'd give it to you," his aunt, Lorna, told The Advocate newspaper. "Alton would give you the world."
One broadcaster, 9News, said Mr Sterling had a long criminal record, that included several battery, drug, and burglary charges. It said he was also arrested in 2009 for resisting an officer and illegally carrying a weapon.
But Lorna Sterling said her brother had sought to earn a living after his last conviction in 2011.
Snowstorms and avalanches have killed 39 trekkers on a popular hiking route in the Himalayas, Nepali officials say.
