Canadian wildfire smoke back AGAIN forcing thousands to evacuate as US fears dangerous air quality

Wildfires have returned to Canada, with the billowing smoke forcing thousands from their homes and raising the alarm about poor air quality in the United States.

The blaze started Friday in northeast British Columbia and almost doubled in size by the start of the weekend, reaching about 4,200 acres and smoldering just a few miles outside Fort Nelson's city limits.

Fort Nelson and the Fort Nelson Indian Reserve have a combined population of about 3,000 people, most of whom have been evacuated according to municipality mayor Rob Frayer.

Data from the National Oceanic and Atmospheric Administration shows smoke beginning to drift into the U.S., with light to medium coverage in Montana, the Dakotas and Minnesota.

These developments have triggered concern about a potential repeat of Canada's 2023 wildfire season, which was the most destructive in the country's history.

Over 6,500 fires burnt nearly 71,000 square miles of land from the West Coast to the Atlantic provinces, and a blanket of smog covered New York City for a three-day period last June, turning the iconic skyline orange.
