Mountain rescue teams and police have issued a warning to walkers after staging six rescue missions and finding the body of a man on Snowdon.
A North Wales Police spokesman urged walkers to stay off the range in the current freezing conditions unless they are experienced walkers with full equipment.
He added that inquiries are ongoing into the identity of the man who was found dead yesterday.
After the man's body was removed from Snowdon, another emergency call came in about two men from a party of four who had fallen yesterday afternoon.
One sustained serious head injuries and was taken to Ysbyty Gwynedd Hospital.
All four were rescued from by the Ogwen Valley Mountain Rescue Team and flown from the mountain by RAF helicopter.
In the nearby Glyder Fach mountain range, the mountain rescue team helped another man who fell, banging his head. He was also taken to hospital.
A woman with an ankle injury was also helped from the mountain and Llanberis Mountain Rescue later searched the Snowdon range for two men from a party of nine walkers, who were reported missing during their walk, but were eventually found safe and well.
The police spokesman said: "North Wales Police and the mountain rescue team are advising only experienced climbers and walkers with axes and crampons, and knowledge of their correct use, to contemplate scaling mountain ranges in the current weather conditions.
"They are also appealing to members of walking groups to make arrangements with friends and family to ensure that if they are missing for any period of time, the police or mountain rescue team should be informed as soon as possible.
"Walkers should also ensure that they have a mobile phone on their person, and that they tell their contacts their planned route and which vehicles they would have access to during this time."Reuse content
