冬季风暴横扫美国，逾110万用户停电、单日九千多架次航班取消
2026年1月25日，一场横扫美国大部的冬季风暴进入东北部并开始转为东北风暴（nor'easter）。这场被气象频道称为「Fern」的风暴自1月23日起自西向东推进，国家气象局的冬季风暴警报一度绵延近2,000英里，覆盖人口超过2.3亿，二十多个州的州长先后宣布紧急状态。
风暴在南部造成破坏性冻雨。密西西比州北部等地结冰厚度达1英寸，压断树木与电线。据停电统计机构 PowerOutage 的数据，1月25日下午4时（美东时间）全美同步停电达到高峰，超过110万用户无电，其中田纳西州约34.5万、密西西比州约18.9万、路易斯安那州约14.3万、德州约14.2万。田纳西州纳什维尔所在的戴维森县当晚一度有九成以上用户停电。
航空交通同样大面积瘫痪。1月25日全美取消航班超过9,000架次，整个周末取消量超过1.1万架次。国家气象局天气预报中心此前警告，南部将出现「灾难性」结冰，停电与树木倒伏会持续多日，风暴过后严寒还会滞留。
这场风暴的降水带从德州延伸到缅因州，多地降雪达1至2英尺，南部以冻雨和雨夹雪为主。各地交通部门呼吁民众避免出行，国民警卫队在十多个州提前部署待命。
Winter Storm Sweeps Across the U.S.: Over 1.1 Million Customers Lose Power and More Than 9,000 Flights Are Canceled in a Day
On January 25, 2026, a winter storm sweeping across much of the United States moved into the Northeast and began transitioning into a nor'easter. The storm, named Fern by The Weather Channel, had advanced from west to east since January 23. National Weather Service winter storm alerts at one point stretched nearly 2,000 miles and covered more than 230 million people, and governors in more than 20 states issued emergency declarations.
The storm brought a damaging ice storm to the South. Ice accretion reached one inch in places including northern Mississippi, snapping trees and power lines under the weight. According to data compiled by PowerOutage, synchronous outages across the United States peaked at 4:00 p.m. Eastern Time on January 25, with more than 1.1 million customers without power, including about 345,000 in Tennessee, 189,000 in Mississippi, 143,000 in Louisiana and 142,000 in Texas. In Davidson County, home to Nashville, Tennessee, more than 90 percent of customers were without power at one point that night.
Air travel was heavily disrupted as well. More than 9,000 flights were canceled across the United States on January 25, and cancellations over the weekend exceeded 11,000. The National Weather Service's Weather Prediction Center had warned of "catastrophic" ice accumulations in the South, with power outages and tree damage lingering for days and bitter cold remaining after the storm passed.
The storm's precipitation shield stretched from Texas to Maine, with snowfall of one to two feet in many places and freezing rain and sleet dominating in the South. Transportation officials urged people to avoid travel, and National Guard units in more than a dozen states were activated in advance.
