I think my Mom and sisters are probably snowed under by now... they're at 7000+ feet up at Tahoe.
At least in Tahoe, you know what to expect with the weather this time of year!
It's kinda like living in Alaska. You prepare for it beginning with the first thaw because you know if you wait for the leaves to fall, or the first snow, it's too late.
They'll be OK, I'm sure!
I grew up skiing at Kirkwood.
