Visitors to Yellowstone National Park should be aware that winter weather is expected in the park this evening, especially on high elevation passes.
Weather can change quickly this time of year in the mountains.
The weather forecast for Friday evening, Sept. 22 predicts 90% precipitation with possible 5-9 inches of snow accumulation on Sylvan Pass, located on the East Entrance Road.
If road conditions deteriorate due to the predicted winter weather, staff will close the East Entrance Road to Sylvan Pass and other roads as appropriate.
If needed, staff will evaluate conditions the morning of Saturday, Sept. 23 and will reopen the road (if it closes) when conditions allow.
