The snowstorm has disrupted travel and outdoor activities in the affected areas, particularly in higher elevations and national parks. Glacier National Park’s Going-to-the-Sun Road, typically accessible in summer, may face closures. U.S. 20 over Targhee Pass, a key route to Yellowstone National Park, is also under a Winter Weather Advisory. Homeowners in the region face risks of frozen pipes and power outages due to the heavy, wet snow. Travelers and hikers are advised to prepare for winter-like conditions, which could pose safety hazards in the backcountry.
