B.C. avalanche warning issued for weekend

A special avalanche warning has been issued for parts of British Columbia this weekend.

The Canadian Avalanche Centre says recreational backcountry users should take extra precautions. It says slopes that would normally be considered safe are now more prone to avalanches.

The warning covers the Columbia Mountains from near Prince George to the U.S. border, the South Rockies and the South Coast Inland Range.

"We have a variety of issues within the snowpack right now that cause us two main concerns," Ilya Storm, the CAC's public avalanche warning services co-ordinator, said in a release.

"The first is that the size of avalanches is likely to be much bigger than might be expected, and could be triggered remotely, which means triggered at a distance or from the bottom of the slope. Our other main concern is that slopes generally considered safer — lower angle, below treeline — are primed for human triggering," Storm said.
