周四傍晚，底特律东区的天空出现了近三十年来未曾有过的一幕。一处屋顶被掀飞，一栋建筑倒塌，一人受伤——一场龙卷风在城区街区间撕开一道长3.5英里、宽半英里的伤痕。2 4 这场龙卷风被确认为EF-2级，峰值风速达每小时115英里，是底特律自1997年以来的首场龙卷风，无人死亡。2 4 当天下午早些时候，林肯公园曾短暂出现一场EF-0级龙卷风，圣克莱尔县也确认发生了另一场龙卷风。2 4

这一个街区讲述的是小故事。大故事则是：这场龙卷风出现在一场罕见的多日强对流天气爆发之中，而这场爆发恰好撞上一年中最繁忙的出行日之一。11 1 周四，超过5000万人处于强对流天气风险区内，这条走廊从五大湖区经俄亥俄河谷一直延伸至大西洋中部地区。11 5 这一地带覆盖密尔沃基、芝加哥、克利夫兰、匹兹堡、巴尔的摩和华盛顿。11

关键事实

  1. 每小时115英里底特律EF-2级龙卷风峰值风速，1997年以来首次 24
  2. 24.36英寸得克萨斯州锡克特降雨量，略超2英尺 1215
  3. 500,000+周五上午停电用户数 106

周四傍晚，美国国家气象局匹兹堡办公室对威斯特摩兰县中部和东南部以及费耶特县东北部发布龙卷风警告，范围包括拉特罗布、默里斯维尔、德尔蒙特、芒特普莱森特和利戈尼尔。11 5 匹兹堡周边测得的阵风最高达每小时75英里。11 山洪袭击俄亥俄州北部，当地家庭乘船获救；俄亥俄州斯普林菲尔德的救援人员则挨家挨户上门。14 20 布法罗创下单日降雨量超过3英寸的纪录，车辆被困在积水街道中。14 20

得克萨斯州两英尺降雨

得克萨斯州受水灾冲击更重。热带风暴爱德华的残余于9月1日在路易斯安那州约翰逊河湾附近登陆，随后停滞在得克萨斯州东南部上空。15 哈丁县锡克特的一个雨量计记录到24.36英寸降雨——略超两英尺。12 15 哈丁县两天内降雨18至20英寸，而该地9月正常总降雨量为5.51英寸。15 山洪紧急状态覆盖孔策-沃伦-锡克特走廊的哈丁、泰勒和波尔克三县，当局救出了数十人。15

到9月3日残余消散时，多日累计降雨量已达15至25英寸，预计河流洪水还将持续数日。15 12 这种雨不会在一夜之间排干，在得克萨斯州东南部的松林地带，云层散去很久之后，小溪仍化作了河流。

到周五上午，从密歇根州到特拉华州长达470英里的地带有超过50万用户停电，主要集中在底特律都市区和宾夕法尼亚州东南部匹兹堡周边。10 6 为底特律都市区供电的DTE能源公司表示，在连续三天的风暴中，其超过45万用户受到影响——周三约10万户，周四约20万户，周五更多。3 10 抢修工作涉及数百根损坏的电线杆，共动员4000人，其中包括1900名互助线路工人。3 该公司承诺在周日结束前恢复所有剩余的风暴相关停电。3

到周日下午，仍有33,238户DTE用户处于断电之中，该公司218万用户中约98%已恢复供电。3 对于那些在假日周末侧耳期待变压器嗡鸣声的家庭来说，周日恢复供电的承诺是唯一重要的时间表。

地面停飞令下的假日出行高峰

风暴恰在出行高峰时来袭。从周四到下一个周三，美国运输安全管理局（TSA）安检人数超过1700万，仅周五一天就约有280万人；同期美国联邦航空管理局（FAA）记录的航班超过28万架次。19 13 全国航班延误超过7000架次，一份针对9月3日至4日的统计显示延误6750架次、取消283架次。8 9 周四，肯尼迪机场的平均地面延误接近两小时，拉瓜迪亚机场约为45分钟。8 9

周五，FAA对杜勒斯、拉瓜迪亚、里根国家机场、巴尔的摩-华盛顿机场和匹兹堡机场实施地面停飞，并对波士顿、拉瓜迪亚和里根国家机场实施地面延误，这场混乱对美国航空的航线网络冲击最大。8 9 达拉斯报告的航班延误率为40%。19 芝加哥奥黑尔机场接待了141万假日旅客，比上一年增长约6%。19

道路过境车辆最多达420万辆。19 明确创下纪录的是油价：假日期间全国油价约为每加仑4.03美元至4.15美元，而上一个劳动节为3.19美元。19 底特律市长玛丽·谢菲尔德表示，该市遭受“严重破坏”，包括一栋建筑被毁和一处屋顶被掀掉。4

第二种危险正在南部和西部酝酿。一个热穹顶盘踞在中部和南部大平原及密西西比河谷上空，使近4500万人直至劳动节都处于高温通报或极端高温警告之下，其中包括圣路易斯。20 18 俄克拉何马州、阿肯色州、密苏里州和密西西比州出现了105或更高的酷热指数。20 堪萨斯城是受灾最重的地区之一，全市区的极端高温警告持续至周六晚间，圣约瑟夫至布恩维尔一线以南地区则持续至周二。20 12

最高气温在95度左右至100度上下，酷热指数接近106，而该市9月初的正常最高气温在80度出头。20 美国国家气象局指出，可能出现连续12天气温达到或超过95度的情况——这将是自2012年7月以来最长的此类持续期。12 20

地点

  1. 1密歇根州底特律
  2. 2宾夕法尼亚州匹兹堡
  3. 3纽约州布法罗
  4. 4得克萨斯州哈丁县锡克特

风暴基本在假日前向北和向东移出。底特律都市区和中西部大部分地区在周五经历了最后一轮强风暴，随后转干，周日和劳动节大多干燥晴朗。5 3 更大范围的天气形势于周六下午南移至南北卡罗来纳州，周日佐治亚州、南北卡罗来纳州和蒙大拿州部分地区仍有轻微强对流风险。5 14 大平原的热穹顶预计不会消散，堪萨斯城的警告持续至周二，而得克萨斯州的河流洪水在降雨停止后仍将持续数日。20 15

播出原貌 12 行
  1. Detroit's first tornado since 1997 hit the east side with 115 mph winds.
  2. It happened as one of the busiest travel days of the year collided with a rare multi-day severe outbreak — more than 50 million people sat in the risk zone, and by Friday morning more than half a million customers were without power across a 470-mile stretch from Michigan to Delaware. So as the holiday rush peaks, the real question is whether this weekend will be remembered as a record — or as near-record travel with a record gas price.
  3. The tornado was confirmed on the city's east side Thursday evening — an EF-2 with 115 mph winds, a damage path three and a half miles long and half a mile wide. It left one person injured, no one killed. Earlier that afternoon, an EF-0 touched down in Lincoln Park, and a separate tornado was confirmed in St. Clair County. The mayor, Mary Sheffield, described significant damage, including a destroyed building and a torn-off roof.
  4. That tornado was part of a corridor stretching from the Great Lakes through the Ohio Valley into the Mid-Atlantic — more than 50 million people were in the Thursday severe weather risk zone, covering Milwaukee, Chicago, Cleveland, Pittsburgh, Baltimore and Washington. Thursday evening, the National Weather Service in Pittsburgh issued tornado warnings for parts of Westmoreland and Fayette counties, including Latrobe, Murrysville and Mount Pleasant, with gusts around Pittsburgh up to 75 mph. Flash flooding hit northern Ohio, where families were rescued by boat, and Springfield, Ohio, where crews went door to door. Buffalo set a daily rain record above three inches, stranding cars in flooded streets.
  5. Texas was hit harder by water. The remnants of Tropical Storm Edouard came ashore September first near Johnson Bayou, Louisiana, then stalled over Southeast Texas. A gauge at Thicket in Hardin County recorded 24.36 inches — just over two feet. Hardin County saw 18 to 20 inches over two days, against a normal September total of about five and a half inches. Flash flood emergencies stretched across Hardin, Tyler and Polk counties, and authorities rescued dozens of people. By the time the remnants dissipated September third, multi-day totals of 15 to 25 inches had fallen, and river flooding was forecast to linger for days.
  6. The power toll was hardest to miss. By Friday morning, more than 500,000 customers were without power across a 470-mile swath from Michigan to Delaware, concentrated in Metro Detroit and around Pittsburgh. DTE Energy said more than 450,000 of its customers were affected across three storm days — roughly 100,000 Wednesday, about 200,000 Thursday and more on Friday. The utility deployed a 4,000-person effort including 1,900 mutual-aid lineworkers, and pledged to restore all remaining outages by Sunday. By Sunday afternoon, 33,238 DTE customers were still in the dark — about 98 percent of its 2.18 million customers restored.
  7. The storm sequence started with Edouard's landfall on September first, then the first severe storms in Michigan the next day, the Detroit tornado on the third, peak outages on the fourth, and by Sunday the utility was still working to restore the last outages.
  8. The storm hit precisely as travel peaked. The TSA screened more than 17 million people from Thursday through the following Wednesday, with roughly 2.8 million on Friday alone. The FAA logged more than 280,000 flights over the same stretch. Flight delays topped 7,000 nationwide, and one compilation for September third and fourth put the figure at 6,750 delays and 283 cancellations. Thursday brought an average ground delay near two hours at JFK and roughly 45 minutes at LaGuardia. Friday brought FAA ground stops at Dulles, LaGuardia, Reagan National, Baltimore-Washington and Pittsburgh, with ground delays at Boston, LaGuardia and Reagan National. Dallas reported a 40 percent flight-delay rate. Chicago O'Hare handled 1.41 million holiday passengers, up about 6 percent from the year before.
  9. Now, about that 'record' claim. The data points to near-record, not record. The TSA projected air travel just below 2025's record, with Friday's 2.8 million screened compared with 2.971 million on the record Friday before Labor Day 2025. The Port Authority of New York and New Jersey counted 6.6 million people using its airports and crossings from September third to eighth, with more than 2.4 million through JFK, Newark, LaGuardia and Stewart — just below the 2.5 million record set in 2025. Road crossings reached up to 4.2 million vehicles. What was plainly a record was the gas: holiday prices ran about $4.03 to $4.15 a gallon nationally, against $3.19 at the previous Labor Day.
  10. A second hazard was building to the south and west. A heat dome sat over the central and southern Plains and the Mississippi Valley, keeping nearly 45 million people under heat advisories or extreme heat warnings through Labor Day, including St. Louis. Heat indices of 105 or higher were recorded in Oklahoma, Arkansas, Missouri and Mississippi. Kansas City was among the hardest hit, with highs in the mid-90s to around 100 and heat indices near 106. The National Weather Service flagged the possibility of 12 consecutive days at or above 95 degrees — the longest such stretch since July 2012 — in a city whose normal early-September highs are in the low 80s.
  11. The storms largely cleared north and east in time for the holiday. Metro Detroit and much of the Midwest saw their last serious round Friday, then dried out, with Sunday and Labor Day mostly dry and sunny. The broader pattern shifted south into the Carolinas by Saturday afternoon, leaving a slight severe risk Sunday in parts of Georgia, the Carolinas and Montana. The Plains heat dome was not expected to break, with the Kansas City warning running through Tuesday and river flooding in Texas lingering for days after the rain stopped.
  12. Authorities were still assessing casualties; there have been reports of deaths amid the tornadoes and flash flooding, though no verified toll has been established. So, was it a record weekend? It produced historic local weather — Detroit's first tornado in nearly three decades, and a Texas rainfall gauge above two feet. But the travel peak it menaced was just short of a record. The record belonged to the price of getting there.
