Winds out of the mountains and gusting up to 71 mph through Paradise Valley have closed Interstate 90 near Livingston, according to the Montana Department of Transportation.
Traffic is being rerouted through Livingston to bypass the interstate from exits 330 to 337, where the wind is averaging about 50 mph.
According to the Montana Highway Patrol, several wrecks this morning on that stretch of interstate prompted the closure. A semi truck, a pickup and a camper all were rolled by the high winds. No details were immediately available on whether the passengers were injured.
Todd Chambers, meteorologist with the National Weather Service, said the winds are forecast to worsen in the evening, potentially reaching gusts up to 80 mph in both Livingston and Nye. A high pressure front in Yellowstone Park is pushing the winds through the valley.
“You’re trying to squeeze a lot of air through a very small area,” Chambers said.
Overnight, forecasters expect gusts to remain dangerously high near the Beartooth and Crazy Mountains from Harlowton to Big Timber and down to Red Lodge, where wind speeds could hit 75 mph.
