The hikers, aged between 25 and 40, had been stranded in a mountain valley about 2,000 metres high around 400 kilometres northwest of Oslo, they said.
They started from the village of Bjorli on February 21 and are scheduled to return tomorrow, police said.
"Several hikers have sent distress messages via satellite during the morning of Friday," Atle von Obstfelder, an operations chief for the Norwegian police's mountain rescue service, told AFP by phone earlier.
Helicopter rescues were attempted twice today, but pilots were forced to turn around because of poor visibility and concerns about triggering avalanches, he said.
