PHILADELPHIA - On air quality maps, purple signifies the worst of it. In reality, it's a thick, hazardous haze that’s disrupting daily life for millions of people across the U.S.
and Canada, blotting out skylines and turning skies orange.And with weather systems expected to hardly budge, the smoky blanket billowing from wildfires in Quebec and Nova Scotia and sending plumes of fine particulate matter as far away as North Carolina should persist into Thursday and possibly the weekend.That means at least another day, or more, of a dystopian-style detour that's chased players from ballfields, actors from Broadway stages, delayed thousands of flights and sparked a resurgence in mask wearing and remote work — all while raising concerns about the health effects of prolonged exposure to such bad air.The weather system that's driving the great Canadian-American smoke out — a low-pressure system over Maine and Nova Scotia — "will probably be hanging around at least for the next few days," U.S.
National Weather Service meteorologist Bryan Ramsey said.Smoke from a raging wildfire in Canada blanketed Philadelphia and surrounding counties in a blanket of haze.
Health officials advised that people should limit their time outside to avoid breathing the air, which has caused particular problems for people with asthma and medical conditions."Conditions are likely to remain unhealthy, at least until the wind direction changes or the fires get put out," Ramsey said. "Since the fires are raging — they’re really large — they’re probably going to continue for weeks.
