US air quality as far south as Virginia affected by Nova Scotia wildfires

National Weather Service issues air quality alert for Richmond while Maryland, Pennsylvania and other states affected

The historically intense wildfires that battered the Nova Scotia province on the eastern coast of Canada have had a severe effect on air quality as far south as Virginia and Maryland, the US National Weather Service alerted.

Four wildfires have destroyed hundreds of buildings and homes and displaced tens of thousands of people, hitting the Halifax municipality hardest. But the blazes have also sent smoke billowing over New York City, and have prompted officials from New Jersey, Pennsylvania, Maryland and Virginia to report negative effects on their air quality.
