So much rain has fallen, that at one point early in the day, Cypress Mountain's website informed skiers "we may encounter ponding of water" on the slopes.
The mountain's crosscountry ski trails are already closed because of the rain.
Self-guided snowshoe trails are shut, while officials say will assess the ability to run group snowshoe programs.
Meanwhile, the downhill skiing and snowboarding area will open only until 3 p.m. PT due to the continued rain.
Mt. Seymour and Grouse Mountain on standby
In the seven days since Jan. 16 only one centimetre of snow has fallen on local mountains and the inclement weather has Mt. Seymour on standby.
All lessons for Friday have been cancelled and mountain staff say they will contact registrants to reschedule.
It's a similar situation on Grouse Mountain - a notice on the resort website says "due to inclement weather, the downhill area will be on standby as of 3 p.m."
Even in Whistler, rain is forecast, not only in Whistler village, but also at the alpine region through Saturday and Sunday, with temperatures expected to remain unseasonably warm.Suggest a correction
