More than 2,400 people are missing and at least 586 have been killed after a wall of water gouged a path through the border region between Nepal and Tibet, sweeping away entire villages.
Here are the latest developments after Wednesday's disaster:
The number of people missing in Nepal and China leaped to 2,478 -- a rise of more than 1,000 from Thursday's figures.
Nepal's disaster agency increased the total toll of people missing on its side of the border to 1,924.
China's Xinhua news agency reported the number of missing in Tibet was now 554.
Nepal's disaster agency said at least 579 people had been confirmed killed and China reported seven.
Canada will provide CAN$5 million (US$ 3.6 million) in "humanitarian assistance to support emergency relief efforts in Nepal", Randeep Sarai, Canada's secretary of state for international development, told reporters.
The European Union on Friday promised two million euros ($2.3 mn) in aid.
European Commission chief Ursula von der Leyen wrote on X that the "immediate humanitarian aid" would help "deliver life-saving assistance to families and communities hit hardest".
The level of trauma cascading from the Nepal flash floods is "enormous", the Red Cross said Friday, with early estimates suggesting 93,000 people may have been affected and that the death toll will continue to rise.
"Due to roads and bridges having been washed out and both cell coverage and electricity cuts, we have not yet been able to access some of the hardest-hit areas," said David Fisher, International Federation of Red Cross and Red Crescent Societies head of delegation for Nepal.
"The trauma of this event is enormous."
Rescuers in the autonomous Chinese region of Tibet have reached the main area wiped out by the devastating mudslide, Chinese state media reported.
"At approximately 4:30 pm (0830 GMT) on 28 August, six members of the first response team from the Fire and Rescue Corps of Tibet and 15 members and one dog from the first response team of the Fire and Rescue Corps of Sichuan arrived at the border area... They are the first professional teams to reach the core rescue site," Xinhua news agency reported.
Nepal issued a warning to move to higher ground after a dam in Tibet was reported to have burst.
China also halted rescue efforts, state media saying a lake formed by immense piles of debris had begun overflowing. State media later said the risk from that lake was "decreasing" and rescue operations were proceeding.
It was not immediately clear if the lake was the same as the dam that Nepalese authorities warned had burst.
Nepal appealed Friday for international financial assistance, but said it was coping without foreign rescue teams.
"It is not that we will not need help, but our security network is capable and working effectively right now," foreign ministry spokesman Lok Bahadur Chhetri told AFP. "If Nepal needs any specialised help or expertise, then we will request it."
Chinese President Xi Jinping offered Beijing's help Friday.
The Nepali military has located people trapped in the tunnel of Trishuli 3A hydropower project, where they were working to bring out survivors.
Army spokesman Raja Ram Basnet told AFP some 350 workers and residents have been brought to safety from the site but there were more than 100 people trapped in the same area.
