Pakistan's government has said it now believes more than 38,000 of its people were killed by the South Asian earthquake a week ago.
That is an increase of more than 13,000 on its previous estimate. The number of injured has risen to more than 60,000.
In some of the areas worst affected, heavy rain and strong winds temporarily grounded helicopter flights.
Relief agencies expressed concern about the weather's effects on the homeless - with children especially vulnerable.
Pakistan military spokesman, Maj Gen Shaukat Sultan, said the death toll in the country had been increased after confirmation of more fatalities in remote valleys and the badly-hit town of Balakot.
He added: "This number is likely to further rise."
Interior Minister Aftab Ahmad Khan Sherpao told the AFP news agency the number of homeless had now risen to around 3.3m.
At least 1,400 people are also known to have died in Indian-administered Kashmir.
Exactly one week after the 7.6 magnitude quake struck, 3,000 Muslim worshippers gathered in the country's largest mosque, in Islamabad, for special prayers.
"Oh Allah, give courage to those who survived this disaster to endure this hardship," the cleric read.
Search abandoned
The UN children's' agency, Unicef, said children in affected areas faced a potentially deadly combination of cold, malnutrition and disease.
Another organisation, Save the Children, said there were reports of children succumbing to exposure.
UK charity Oxfam said thousands of tents and blankets needed to be moved into remote areas where roads were barely passable at the best of times.
Villagers have been walking to relief camps to beg for tents.
Mohammed Qassim, who lives in Tungli village, five kilometres (three miles) from Balakot in Pakistan, told Associated Press: "We're asking for just one tent. For the sake of God, please give me one tent. Three families can live in it."
Rescue workers have now abandoned the search for survivors, although an 18-month girl was found in a remote village in North-West Frontier Province on Friday.
Heavy rains all Saturday morning stopped helicopters flying aid to remote areas, though they have now restarted.
Altuf Musani, World Health Organisation coordinator in Muzaffarabad, Pakistan-administered Kashmir, said: "In these conditions, people will freeze. They will suffer hypothermia.
"There is a small window of less than a week to get to them. Those who are critically injured have very little chance."
UN top relief co-ordinator, Jan Egeland, has said billions of dollars will be needed for the aid effort.
On Saturday, Saudi Arabia announced an aid package worth $133m for Pakistan.
The Dalai Lama expressed his sorrow at the earthquake and pledged $23,000 in aid for Pakistan and $12,000 to India.
