蒙大拿与怀俄明大角山区冬季风暴观察：降雪可达8英寸 阵风50英里
2026年11月1日，美国国家气象局比灵斯预报站针对蒙大拿州大角县普赖尔地区及北部大角山脉发布冬季风暴观察预警，预警有效期为11月1日星期日晚至11月2日星期一晚。预报称，上述山区可能出现中到大雪，降雪量可达8英寸，阵风可达每小时40至50英里，吹雪可能使能见度降至四分之一英里以下。
怀俄明州东北部大角山脉也被列入同一预警范围。气象部门提醒，山区道路可能出现积雪和结冰，驾驶员在夜间和星期一早通勤时段应格外谨慎，预留充足行车时间，关注实时路况更新。冬季风暴观察预警意味着恶劣天气有可能发生，但尚未达到冬季风暴警告的确定程度，预报仍可能随气流变化调整。
蒙大拿州北部落基山地区在11月初进入降雪多发期，山区居民和过往司机应提前检查车辆防滑设备、保暖衣物和应急物资，避免在能见度极低时冒险翻越山口。国家气象局将根据最新观测持续更新降雪量和风力预报，公众可通过官方渠道查询分时段预报。
Winter Storm Watch for the Bighorn Mountains: Up to 8 Inches of Snow, 50 MPH Gusts
On November 1, the National Weather Service office in Billings issued a winter storm watch for the Pryor area and the northern Bighorn Mountains in Big Horn County, Montana, in effect from Sunday evening, November 1, through Monday evening, November 2. Moderate to heavy snow is possible in the mountains, with totals up to 8 inches, wind gusts of 40 to 50 mph, and blowing snow that could drop visibility below a quarter mile. The northeastern Bighorn Mountains in Wyoming are included in the same watch area.
Forecasters warned that mountain roads may see snow and ice, and that drivers should take extra care at night and during the Monday morning commute, allow plenty of travel time, and follow real-time road updates. A winter storm watch means hazardous weather is possible but has not yet reached the certainty of a winter storm warning, and the forecast may still change with shifting air currents.
Northern Rocky Mountain areas in Montana are entering their snowy season in early November. Mountain residents and through drivers should check vehicle traction equipment, warm clothing and emergency supplies in advance, and avoid crossing passes when visibility is extremely low. The National Weather Service will keep updating snowfall and wind forecasts from the latest observations, and the public can check hourly forecasts through official channels.
