Thursday, December 29, 2022. Grand Canyon has been experiencing a wide variety of winter weather phenomena over the past 48 hours: fog, hoar frost, inversions, thunder snow, hail, rain and snow showers, along with hours of limited visibility followed by moments of brilliant sunshine. We're expecting another round of winter weather to arrive Saturday night, and into New Year's Day, with widespread snow Sunday, January 1. So, unfortunately, we will be dealing with hazardous driving conditions as we ring in the New Year. What should you do if you have to travel? The best thing you can do is SLOW DOWN! It is not safe to drive anywhere close to normal highway speeds on icy roads. You can easily lose control. Don't use cruise control. Roads can be slick, even if they just look wet. Leave extra distance between vehicles. — Ice and snow, take it slow. Here are captions for the photos in this post. (All are NPS photos) 1-3) Mather Point, Wednesday afternoon.
