Air quality alerts issued for Massachusetts as wildfire smoke blankets the region
Key Points:
- A thick plume of wildfire smoke from Ontario, Canada, and northern Minnesota has drifted into New England, causing hazy, yellow-brown skies and triggering air quality alerts across the eastern U.S., including New York, Philadelphia, D.C., and the Great Lakes region.
- The smoke has significantly reduced visibility, with reports of dense, fog-like conditions in northern Wisconsin, heavy haze in New Hampshire, and an air quality index reaching "unhealthy for sensitive groups" in Boston.
- High-altitude winds, influenced by the jet stream, funneled the smoke directly into the Northeast, creating a widespread impact on air quality and respiratory health, especially for those with asthma or COPD.
- The smoke is expected to thin overnight Wednesday but will return in a second wave Thursday afternoon, bringing another round of thick smoke and smoky odors across central and southern New England.
- Despite the health concerns, the smoke is also causing vivid sunrises and sunsets due to the scattering of light by the smoke particles.
