Affected by heavy smoke from the Canadian wildfires, as of the morning of July 18, local time, air quality warnings had been issued in more than 10 states, extending from the upper midwest of the United States and the Great Lakes region to the New England region, and south covering the northeastern part of the Atlantic. According to reports, there are currently more than 900 wildfires burning in Canada, and large amounts of smoke continue to drift towards the northeastern United States and the Mid-Atlantic region. However, a storm system that will pass on the 18th is expected to help disperse some of the haze. Meanwhile, driven by northwest winds, a heavy smoke belt is entering the Midwestern United States and the upper Great Lakes region. Local air quality is expected to remain poor throughout the weekend.
