I haven’t been up to Sugarloaf yet this season, but I would guess that there is probably enough snow to get up to Portuguese Pass, the road up there stays very well shaded and tends to hold snow for a while.
I was up at Sherman 2 weekends ago and there was actually a surprising amount of snow in spots. Up to two feet of nice powder on some well shaded trails.
As an aside, could you send me a link to that webcam if it is public? I’d love to put it in the website’s weather page.
