Idaho Falls, Idaho – Drivers across eastern Idaho could face sudden crosswinds within hours as powerful gusts up to 60 mph begin hitting major travel corridors by 9 a.m. Thursday, creating dangerous conditions for trucks and high-profile vehicles on open highways like I-15 and U.S. 20.
According to the National Weather Service in Pocatello, a High Wind Warning remains in effect from 9 a.m. until 9 p.m. MDT Thursday for the Upper Snake River Plain, Teton Valley, the Arco/Mud Lake Desert, and the Southern Hills and Albion Mountains. Sustained southwest winds of 30 to 40 mph with gusts reaching 60 mph are expected, with isolated higher bursts possible in exposed desert and valley locations.
Communities including Idaho Falls, Rexburg, Driggs, Ashton, Tetonia, Mud Lake, St. Anthony, and Albion could see blowing debris and sudden gusts along open stretches of roadway. Transportation officials warn that crosswinds may push vehicles across lanes, particularly on elevated bridges and rural highways.
Power companies are also monitoring conditions as strong gusts could snap tree limbs or damage power lines, potentially leaving isolated neighborhoods without electricity. Rural areas near Craters of the Moon and the Idaho National Laboratory corridor are especially exposed to strong desert winds.
Residents should secure patio furniture, trash bins, and other loose outdoor items before winds strengthen. Drivers should keep both hands firmly on the wheel and consider delaying travel if operating RVs, trailers, or semitrucks.
Wind impacts are expected to gradually ease after 9 p.m. Thursday, though additional advisories could be issued if strong gusts persist into the evening.
