We live in southern Oregon and it should be no problem but check the ODOT weather cams in advance. We are not expecting any rain or snow through Christmas. They are doing work on the I-5 near Ashland and it is slowing things down a lot. It is always best to travel the passes this time of year during the middle of the day if you can plan it that way.

Click on the little camera for each location for both the report and current photo. You can even look at the pretty snow at Crater Lake. They have cameras for north and south views.
You can e-mail us privately if you need any information you think we can provide.
