加拿大野火烟雾正在渗透中西部,芝加哥的空气已经恶化到空气质量指数“非常不健康”类别。

周二下午,芝加哥雾霾天气的空气质量指数达到了250。对于敏感人群来说,任何超过100的数字都被认为是不健康的。

芝加哥市长布兰登·约翰逊周二在一份声明中警告说,“我们建议儿童、青少年、老年人、心脏病或肺病患者以及孕妇避免剧烈活动,并限制他们的户外时间。对于额外的预防措施,所有芝加哥人也可以考虑戴口罩,限制户外暴露,将活动转移到室内,运行空气净化器,并关闭窗户。”

周二早上,世界上空气质量最差的是威斯康星州。

该州自然资源部发布了全州空气质量公告,有效期至周四。

周二下午,密尔沃基的空气质量指数处于“非常不健康”的类别。

威斯康星州自然资源部表示,“预计6月27日周二中午至6月28日周三中午之间,空气质量和健康影响最大。”。“这是一个动态的情况,未来几天情况可能会迅速变化。密切关注你所在地区的空气质量并采取行动很重要,尤其是在你感觉不舒服的时候。”

到星期二晚上,最浓的烟雾将出现在包括伊利诺伊州斯普林菲尔德在内的城市;伊利诺伊州皮奥里亚;肯塔基州的路易斯维尔和弗吉尼亚州的罗阿诺克。

周三早上,从爱荷华州到北卡罗莱纳州,雾霾都很明显。据预测,爱荷华州锡达拉皮兹和密苏里州圣路易斯附近的城市烟雾最强。

周三下午,烟雾将开始稍微减弱,但预计从明尼苏达州到北卡罗来纳州的空气质量仍会下降。

甚至东北部也可能受到影响。纽约市长埃里克·亚当斯警告说,纽约人周三可能会经历更糟糕的空气质量,纽约州州长凯西·霍楚尔说,纽约北部的几个地区已经发布了空气质量健康咨询。

预计从周三晚上到周四,烟雾会明显减少。从密歇根州到乔治亚州,天空仍将是乳白色的,患有哮喘和其他呼吸系统疾病的人可能仍会呼吸困难。

据预测,周五阵雨和雷雨袭击该地区时,烟雾将会消散。

本月早些时候加拿大野火的烟雾飘向东北方向,纽约市、费城和华盛顿特区笼罩在危险的橙色烟雾中,十几个州发出了严重的空气质量警报。6月7日,纽约市的空气质量指数达到484,创历史最高水平。

Chicago air quality hits 'very unhealthy' category as Canadian wildfire smoke infiltrates Midwest

Canadian wildfire smokeis infiltrating the Midwest on Tuesday and the air in Chicago has deteriorated to theAir Quality Index's "very unhealthy"category.

The AQI in hazy Chicago reached 250 on Tuesday afternoon. Any number over 100 is considered unhealthy for sensitive groups.

Chicago Mayor Brandon Johnson warned in a statement Tuesday, "We recommend children, teens, seniors, people with heart or lung disease, and individuals who are pregnant avoid strenuous activities and limit their time outdoors. For additional precautions, all Chicagoans may also consider wearing masks, limiting their outdoor exposure, moving activities indoors, running air purifiers, and closing windows."

The worst air quality in the world Tuesday morning was in Wisconsin.

The state's Department of Natural Resources issued a statewide air quality advisory that's in effect until Thursday.

On Tuesday afternoon the AQI in Milwaukee registered in the "very unhealthy" category.

"The most significant air quality and health impacts are anticipated between noon on Tuesday, 6/27 and noon on Wednesday, 6/28," Wisconsin's Department of Natural Resources said. "This is a dynamic situation, and conditions may change rapidly over the next few days. It is important to pay close attention to the air quality in your area and take action, especially if you don’t feel well."

By Tuesday evening the densest smoke will be in cities including Springfield, Illinois; Peoria, Illinois; Louisville, Kentucky and Roanoke, Virginia.

On Wednesday morning, the haze will be noticeable from Iowa to North Carolina. The smoke is forecast to be strongest in cities near Cedar Rapids, Iowa, and St. Louis, Missouri.

On Wednesday afternoon, the smoke will start to weaken slightly but reduced air quality is still expected from Minnesota to North Carolina.

Even the Northeast could see an impact. New York City Mayor Eric Adams warned that New Yorkers could experience worse air quality on Wednesday and New York Gov. Kathy Hochul said air quality health advisories have been issued for several upstate New York regions.

The smoke is expected to lessen significantly Wednesday night into Thursday. A milky sky is still expected from Michigan to Georgia and those with asthma and other respiratory issues may still have difficulty breathing.

The smoke is forecast to clear on Friday when showers and thunderstorms hit the region.

Earlier this month theCanadian wildfire smoke drifted toward the Northeast, blanketing New York City, Philadelphia and Washington, D.C., in a dangerous orange haze and prompting serious air quality alerts in over a dozen states. On June 7 New York City's AQI hit 484, the highest level on record.
