One woman in Wales is waiting to hear news of a missing man she considers family, who was working in a hydropower station in Nepal when the floods hit.
Jyoti Upadhyay, who is from Nepal but has lived in Tal-y-bont in Ceredigion for the past five years, says she and her husband have not been able to find out anything about the whereabouts of worker Jit Bahadur Chaudhary.
Chaudhary, who is not a blood relation but is considered family by Upadhyay as he has lived with her mother-in-law for the past 25 years, was working at the Trishuli-3B site, one of several sites that have workers trapped inside them.
Nepali authorities are blasting into hillsides to try and reach those trapped, with a controlled blast carried out at the Trishuli site in an attempt to open up access in the early hours of Monday.
"To be honest since Saturday we have lost hope," Upadhyay tells BBC Radio Cymru's Bwrw Golwg programme.
"It has been extremely difficult to reach the site. What we understand is that all the buildings are under meters of mud and it has been impossible to search for anyone there."
