(CNN) — Thick, choking plumes of smoke from Canadas wildfires are pouring into major cities across the Midwest, Northeast and Mid-Atlantic, bringing dangerous air quality to more than 100 million people. The polluted air will last through at least Saturday in some areas as new waves of smoke waft so
Key takeaway Here’s the latest: • Choking air pollution: More than 100 million people in 18 states and the District of Columbia are under Air Quality Alerts, many of which note that the air pollution is so high, even healthy adults will be affected.
Why this matters in The Miami
Miami 's unique geography, with its coastal location and subtropical climate, may shield it from the worst of the Canadian wildfire smoke, but the city's residents should still be aware of the potential health impacts. As a major hub for Latin American and Caribbean communities, Miami's population may include individuals with pre-existing health conditions, such as asthma or heart disease, that could be exacerbated by poor air quality. Although the smoke is currently affecting the Midwest, Northeast, and Mid-Atlantic, Miami's proximity to the Atlantic and potential for hurricane-related weather patterns means that wind directions can shift quickly, potentially bringing smoke into the area. Miami-Dade County's public health infrastructure, including the Miami-Dade County Public Schools and the Miami-Dade Police Department, should be prepared to respond to any potential air quality issues that may arise, particularly in neighborhoods like Little Havana and Wynwood, which are densely populated and may be more vulnerable to poor air quality.
