Smoke from devastating wildfires in Canada has drifted south, causing hazardous air quality in major US cities. A thick haze descended on metropolitan areas Friday, prompting health advisories and concerns for residents. The situation is particularly worrying as it coincides with preparations for the FIFA World Cup final scheduled near New York City. The match is set to be played at an outdoor stadium, raising questions about potential disruptions or safety measures. Organizers are closely monitoring the air quality conditions and assessing potential impacts on the event. The extent of smoke coverage and potential for improvement remain uncertain.
