Police co-ordinating the search for a missing Worcester hillwalker on Britain's highest peak admitted it is highly unlikely that he is alive.
Haider Ali Manir failed to return from a hike on Ben Nevis near Fort William on Sunday.
The 20-year-old was reported missing by his cousin who descended the mountain without him.
He is thought to have been ill-equipped for the extreme weather conditions in recent days which continue to hamper the rescue effort.
Chief Inspector John Chisholm from Northern Constabulary said: "The passage of time, coupled with the severe weather up on the mountain, sadly indicates that it's highly unlikely Mr Manir has survived.
"The weather here has made it impossible to search and indeed the Met Office has predicted further severe weather for the next two days.
"It may be possible to conduct a further search at the weekend if conditions permit."
Lochaber mountain rescue team, the Search & Rescue Dog Association Scotland and the RAF mountain rescue service are among teams who have tackled the mountain in white-out conditions in a bid to trace Mr Manir.
John Stevenson, leader of Lochaber mountain rescue team, said: "I am satisfied that we have conducted a saturation search in extremely hazardous conditions.
"Search personnel encountered white-out conditions near the summit of Ben Nevis with blowing snow and ice underfoot.
"We have a severe forecast over the next few days and this will prevent further search activity. We hope to resume our efforts when a suitable weather window permits."
