The upcoming World Cup final between football powerhouses Spain and Argentina at MetLife Stadium in New Jersey this Sunday, July 19, has been clouded by growing concerns over smoke drifting from wildfires in Canada.

With a significant portion of the U.S. sky blanketed by smoke, FIFA is closely monitoring the situation as the championship match approaches.

Andrew Giuliani, Executive Director of the White House World Cup Task Force, stated that they are keeping a constant watch on the situation in collaboration with experts from the National Weather Service.

According to data from the Canadian Wildland Fire Information System, 888 wildfires were active across Canada as of Friday, most of which remain out of control. Over 190 of these fires are currently burning in Ontario, many of which are similarly uncontained.

The smoke poses a major logistical challenge for the United States, as more than 80,000 spectators are expected to pack MetLife Stadium for what is being billed as the largest World Cup final in history.

U.S. President Donald Trump is scheduled to be present in the VIP gallery, marking his only appearance at a match during this tournament. At the President’s invitation, Mexican President Claudia Sheinbaum will also be in attendance to enjoy the final.

For Argentina, led by Lionel Messi, the match represents a historic opportunity to become the first team since Brazil in 1962 to win back-to-back World Cup titles. Meanwhile, Spain is eager to secure its second World Cup trophy, having last won the title in 2010.
