Here are the goods for up here. Quite honestly, I feel sad for our American friends who booked their long weekend at Whistler based on the expectation that there would be bottomless powder to shred.
Unfortunately - that fell apart yesterday afternoon, when the freezing level started moving up and went up to near the top last night - essentially turning all the 17 feet of fresh snow from the past couple of weeks to concrete on most the mountain. The exception being the top of 7th heaven and the Horstman glacier area, where it's been snowing all along.
At the moment, the snow line is dropping back down toward mid-mountain. By the time the thanksgiving weekend starts tomorrow morning, there should be about 8 inches of fresh on the upper half of the mountains. In a nutshell, the groomed slopes should be fantastic, and off-piste at the very top you might find some deeper stuff.
Having said that - I'm sure the folks on this thread from Colorado will be thinking, "there ya go, raining in Whistler as usual!" Well, the reality is, we've got 3 days of sunshine in the forecast - so all is not lost. It's just unfortunate that the one storm that decided to be warm (as opposed to the last 10 colder storms) to roll through here would arrive just before U.S. the holiday weekend.
And in the last 24 years that I've been here, I've found it to be rare for rain events to happen in the alpine.
