Residents of Wyoming, especially those in the Sierra Madre Range, Snowy Range, Southwest Wyoming, Wind River Mountains West, Teton and Gros Ventre Mountains, Yellowstone National Park, and the Salt River and Wyoming Ranges, are advised to brace for significant winter weather conditions. Effective immediately, the National Weather Service has issued a Winter Weather Advisory, with snow accumulations ranging from 2 to 12 inches, depending on the area, and wind gusts reaching 45 mph. Visibility may be severely reduced, making outdoor activities very risky. Expect difficult travel conditions over mountain passes and in affected areas until 6 PM MDT on April 1. Residents and travelers should exercise extreme caution and prepare for the possibility of road closures and hazardous driving conditions.
