Mark Diggins, co-ordinator of sportscotland's Avalanche Information Service, based at Glenmore Lodge, explained the latest tragedy had been caused by a slab avalanche
"This is when a sheet of dense snow is formed by the wind driving it in such a way it forms a hard slab on an area of existing snow. But the problem arises when it overlies a weak layer snow which then fails," he said.
