Winter Has Already Arrived in Yellowstone National Park!

Hard to believe, but winter has already arrived in Yellowstone National Park! If you’re planning to visit, please note that tonight, winter weather is expected, especially in high-elevation areas.

Mountain weather can shift rapidly this time of year, so be prepared.

The forecast for Friday evening, September 22, predicts a 90% chance of precipitation with the possibility of 5-9 inches of snow on Sylvan Pass along the East Entrance Road.

In case road conditions worsen due to the anticipated winter weather, park staff will close the East Entrance Road to Sylvan Pass and other relevant roads.

If necessary, they’ll assess the situation on the morning of Saturday, September 23, and reopen the road when conditions permit.
