The strongest winds are expected across the eastern Magic Valley, Snake River Plain, the INL, and the Lava Beds near Craters of the Moon.

Winds will gust 50 to 70 mph, with isolated areas near 80 mph on eastern mountain slopes like the Absaroka and Wind River Mountains. Mountain passes such as Teton, Togwotee, and South Pass will be extremely difficult to traverse due to blowing snow and poor visibility.
