Advisory from the National Weather Service starting around Thursday, Oct 6.
If anyone's heading that way on two wheels this weekend, you may want to think about re-routing. Excerpt:
MOTORISTS DRIVING OVER MOUNTAIN PASSES SHOULD BE PREPARED FOR FAST CHANGES WITH RAIN CHANGING OVER TO ACCUMULATING SNOW. HEAVY SNOW AND DENSE FOG WILL CAUSE POOR VISIBILITY. ACCUMULATING SNOW WILL CAUSE SLUSHY AND SLIPPERY CONDITIONS OVER THE MOUNTAIN PASSES. TRAVELING INTO THE HIGH COUNTRY WILL BECOME CHALLENGING IF ONE IS NOT PREPARED FOR THE FIRST SIGNIFICANT WINTER STORM OF THE SEASON.
