Residents of Idaho, particularly those in the mountains near Island Park, West Yellowstone, Cooke City, Centennial Mountains, Sawtooth/Stanley Basin, and the Sun Valley Region, are urged to exercise extreme caution due to multiple avalanche warnings and winter storm advisories. The avalanche danger is high, with natural and human-triggered slides very likely. Heavy snow accumulation is expected, impacting travel conditions and potentially the Monday morning commute. Those in the Southwest Highlands should also be prepared for high winds with gusts up to 50 mph. Please stay informed, avoid high-risk areas, and prepare for challenging road conditions.
