The same system that brought heavy rain to B.C'S coast this week has also been bringing as much as 60 cm of snow to the province's higher elevations.
Forecasters are warning of a high-to-extreme avalanche risk over the weekend, especially in the Sea-to-Sky, South Columbia and Monashees & Selkirk regions.
On Friday, those three regions were listed at the rare "extreme" level by the Canadian Avalanche Centre, and is forecast to remain high through the weekend across almost all of the province's major ranges.
Avalanches have claimed the lives of three people this season, and any slides this weekend could be the strongest so far this year.
Some could be strong enough to seriously injure or kill a person, bury cars or destroy trees and sheds.
"Both Mt. Seymour and Cypress Mountain are closed today," Weather Network reporter Ian Jacobs said from Vancouver on Friday.
"Officials say it's the combination of warm temperatures, rain and snow that's causing an unstable snowpack that does not react well to rapid change -- like the amount of rain we've seen since Thursday morning and a lot of snow at the higher elevations."
Both ski resorts reported on their websites that they intended to re-open Saturday.
