CHEYENNE, Wyo. — Heavy snow has slowed travel in the Jackson Hole region of northwest Wyoming and in the Snowy Range area of the south-central part of the state.
The National Weather Service posted winter storm warnings for both areas Friday.
Areas of the Jackson Hole Valley have received up to 12 inches of snow. Teton Pass between Jackson and the Idaho border was closed Friday morning. Many other highways and roads in the area were slick.
Sylvan Pass in Yellowstone National Park was closed much of Friday because of avalanche danger.
In south-central Wyoming, up to 22 inches of snow fell in the Snowy Range. The snow slickened parts of Interstate 80, but conditions improved as the day wore on.
