Widespread Code Red Air Quality Alerts in the Midwest and Appalachia

Heavy smoke from wildfires in Canada has caused poor air quality across northern, western, and central West Virginia, with some areas experiencing "very unhealthy" conditions. People, especially those with respiratory conditions, are advised to avoid prolonged outdoor exposure. The smoke haze is expected to worsen before clearing out by Thursday afternoon. Detroit, Pittsburgh, and Indianapolis are also affected by the fires' impact on air quality.
