伊利诺伊州Kankakee河谷遭EF3级龙卷风致3人死亡，同场风暴降下6.6英寸州纪录冰雹
2026年3月10日下午至傍晚，美国伊利诺伊州北部与印第安纳州西北部遭多股强超级单体雷暴横扫。其中一条 Kankakee 至 Roselawn 龙卷风被美国国家气象局定级为 EF3 级：峰值风速每小时160英里，路径长35.62英里、最大宽1550码，造成3人死亡、11人受伤。
据国家气象局芝加哥办公室3月24日发布的定版灾害调查，这条龙卷风于3月10日18时21分在伊利诺伊州 Kankakee 县 Kankakee 市西南方生成，向东北方向穿过 Kankakee 南部与 Aroma Park，跨过州界进入印第安纳州的 Lake Village 与 Roselawn 一带，19时39分在 De Motte 以西消散。Aroma Park 东北的 Sandbar 路一带三栋住宅被完全摧毁，一辆重型皮卡被卷出100多英尺。同一超级单体当天共生成12条龙卷风，国家气象局芝加哥责任区确认10条。
同场风暴还降下特大冰雹：一户居民在 Kankakee 西南部拾得一颗直径6.6英寸的冰雹，经北伊利诺伊大学以三维激光扫描测量体积与直径，2026年8月经州气候极值委员会审查、国家环境信息中心批准，确认为伊利诺伊州直径、体积与重量三项纪录，超过2015年在 Minooka 创下的4.75英寸旧纪录。
风暴来临前，风暴预测中心当天对该地区发出罕见的五级制第4级（Moderate）强对流风险，龙卷风警戒在龙卷风生成两小时前已发布，各条龙卷风发生前均有龙卷风警告在效。
EF3 Tornado Kills Three in Illinois' Kankakee River Valley as Same Storm Drops Record 6.6-Inch Hail
On the afternoon and evening of March 10, 2026, intense supercell thunderstorms swept northern Illinois and northwestern Indiana in the United States. The strongest, the Kankakee-to-Roselawn tornado, was rated EF3 by the National Weather Service: with peak winds of 160 mph, a path 35.62 miles long and up to 1,550 yards wide, it killed three people and injured 11.
According to the final damage survey issued by the National Weather Service office in Chicago on March 24, the tornado began at 6:21 p.m. CDT southwest of Kankakee in Kankakee County, Illinois, traveled east-northeast through southern Kankakee and Aroma Park, crossed into Indiana through Lake Village and Roselawn, and dissipated west of De Motte at 7:39 p.m. Along Sandbar Road northeast of Aroma Park, three homes were completely destroyed and a heavy pickup truck was moved more than 100 feet into a ditch. The same supercell produced a family of 12 tornadoes that day, 10 of them confirmed in the Chicago office's area of responsibility.
The storms also produced exceptionally large hail. A hailstone measuring 6.6 inches in diameter, collected by a family on the southwest side of Kankakee and measured by 3D laser scanning at Northern Illinois University, was reviewed by the State Climate Extremes Committee and approved by the National Centers for Environmental Information in August 2026 as the Illinois state record for diameter, volume and weight, surpassing the previous record of 4.75 inches set at Minooka in 2015.
Before the storms developed, the Storm Prediction Center had issued a rare Level 4 out of 5 (Moderate) risk for severe weather over the area, a Tornado Watch was in effect more than two hours before the Kankakee-Roselawn tornado began, and Tornado Warnings preceded each confirmed tornado.
