Smoke from Canadian wildfires triggered air quality alerts in more than a dozen U.S. states Wednesday, with health officials warning people, especially those in sensitive groups, such as children, the elderly or with respiratory conditions, to limit their time outdoors or stay inside.
In New York City, the thick haze forced public schools to cancel outdoor activities, and the Federal Aviation Administration issued a ground stop at LaGuardia due to low visibility.
