Air quality warnings are expected to remain in place across large parts of the United States on Saturday, as heavy wildfire smoke from the Canadian province of Ontario and the US state of Minnesota continues to drift across the country, according to the National Weather Service.
Thunderstorms May Bring Temporary Relief but New Risks
Some areas in the mid-Atlantic and north-east regions will continue to experience poor air quality until Saturday afternoon, with a high chance of thunderstorms. These storms could provide some reprieve from the smoke but also pose risks such as flash flooding and high winds, officials warned.
Parts of the midwest and Great Lakes regions will also see dangerous air quality levels persist, the National Weather Service reported.
World Cup Final Expected to Proceed Despite Smoke Concerns
The smoke has raised questions about air quality in New Jersey, where the World Cup final between Spain and Argentina is scheduled for Sunday in East Rutherford. However, winds are pushing the wildfire smoke eastward, and conditions should improve by match day, according to forecasters.
Bob Oravec, a lead forecaster at the National Weather Service based in Maryland, told the Associated Press that while there may be pockets of relief, such as this weekend, the smoky conditions will not disappear soon as the fires continue to burn largely unchecked.
Ongoing Wildfires and Evacuations
Out-of-control wildfires continue to burn in Ontario and the Boundary Waters Canoe Area Wilderness in Minnesota, which US officials have closed as they fight the blazes. Flames in northern Ontario have destroyed the Namaygoosisagagun First Nation community, and nearly a dozen other communities have been evacuated or are being evacuated.
For much of the past week, tens of millions of people across Canada and the US have been breathing unhealthy air, leading to eye irritation, temporary business closures, and cancellation of many outdoor events.
Worst Air Quality Recorded in Several States
On Friday, communities in Minnesota, Illinois, Michigan, and the US north-east, including Detroit and Washington DC, registered some of the worst air quality in the world, according to IQAir, an air quality monitoring website. Skies appeared a hazy orange hue for much of the day.
People, particularly those with heart or lung disease, older adults, pregnant women, and children, were urged to limit or avoid going outside until air quality improved. Officials in New York, New Jersey, Pennsylvania, and other north-eastern states distributed free K95 face masks for those who had to go outside.
Health Risks and Climate Connection
Long-term exposure to smoky conditions can complicate existing health problems and lead to chronic and deadly issues, including respiratory illness, cardiovascular and neurological diseases, and premature death. Wildfire smoke is linked to tens of thousands of deaths annually, and scientists estimate that the human-driven climate crisis is responsible for a growing share of these fatalities, according to research.
