inches above 9000 feet, with 2 to 4 inches between 7000 and
9000 feet.

* WHERE…Teton and Gros Ventre Mountains.

* WHEN…From 11 PM Sunday evening to noon MDT Monday.

* IMPACTS…Plan on slippery road conditions especially over

There is the potential that snow levels could fall further than 5500 feet, which would allow rain to mix with or change over to all snow at lower elevations. Those with travel plans over mountain passes should be prepared for slippery road conditions and periods of reduced visibility. Given the heavy and wet nature of the snow, vegetation with foliage could be damaged due to the weight of the snow. Wet and raw backcountry conditions will exist through Monday.

Most of Yellowstone National Park should see snow accumulations, up to 4″. Snow is not forecast to accumulate in Jackson Hole, WY.
