Hundreds of thousands told to stay indoors in 3 states

Residents living across a huge area spanning three states have been warned of dangerous air pollution levels on Tuesday.

Swathes of Minnesota, Iowa and Wisconsin are all affected by poor air quality, with an area around Minneapolis covered by one of the most severe warnings.

Smoke from wildfires, combined with the current weather conditions, have contributed to the pollution.

Health officials warn that vulnerable populations — such as children, older adults and individuals with existing respiratory issues — face heightened risks during periods of poor air quality. Even healthy members of the general public may experience health effects when air pollution reaches dangerous levels.

Minnesota has been beset by wildfires this week, adding misery to the devastation already caused by a string of blazes last month that consumed more than 35,000 acres of land.

The U.S. Environmental Protection Agency's (EPA) AirNow map, which offers a real-time snapshot of air quality, shows that air pollution levels across swathes of Minnesota, and parts of Iowa and Wisconsin, are deemed to be "unhealthy."

The Minnesota cities facing a red warning - with Air Quality Index (AQI) scores of between 151-200 - include Rochester, Willmar and Duluth.

The red warning means that "some members of the general public may experience health effects," while members of sensitive groups "may experience more serious health effects."

Meanwhile, a large area around Minneapolis faces a purple warning, which means air quality is "very unhealthy," with AQI scores of between 201-300. That is the second more severe reading, and indicates that the "risk of health effects is increased for everyone."

The towns of Ramsey, Lakeville and Faribault are also covered by the purple warning.

Meanwhile, in Wisconsin, the northwestern part of the state is affected by a red warning, including the Saint Croix Reservation and the city of Cumberland.

A large part of northern Iowa is also covered by a red warning, including the cities of Spencer and Storm Lake.

某年开车送朋友去优山美地一日游。去的时候封了路要绕道进峡谷。返程（下山）时候见到封路的原因，巨大的烟尘柱。很多人停车拍照。

看见烟不算。

当时我看到整座山都是红彤彤的火。
