⚠️ Air quality alert in effect for New York and nine other states
Friday, June 13, 2025 – New York (7:30 AM local time) – Extremely poor air quality is impacting a large portion of the Northeastern and Midwestern United States, including New York, New Jersey, Pennsylvania, and Maryland. The National Weather Service (NWS) and local health authorities have issued air quality alerts, urging people—especially sensitive groups like seniors, children, and those with asthma or other respiratory conditions—to avoid prolonged outdoor activities and limit all unnecessary driving.
🚗 Why you should avoid driving today in New York
Officials are asking residents across New York State, including New York City, to reduce vehicle trips, refrain from idling engines, and avoid outdoor burning, as these actions worsen ground-level ozone levels. The current alert is tied to high concentrations of ozone and fine particulate matter—both major contributors to smog and respiratory problems.
The New York State Department of Environmental Conservation (NYSDEC) reported that ozone levels have surged into the “unhealthy for sensitive groups” range. This means infants, the elderly, and those with existing heart or lung diseases are at increased risk of serious health effects.
🌫️ What’s causing this air quality crisis
In Minnesota, Wisconsin, and parts of Ohio, air quality alerts stem from Canadian wildfire smoke. This smoke has traveled southeast, affecting states as far as Virginia and the District of Columbia. In New York, the problem is compounded by stagnant air masses and high temperatures, which create the perfect environment for ozone formation.
According to AccuWeather meteorologist Brandon Buckingham, ozone is not directly emitted, but forms when sunlight and heat trigger chemical reactions between pollutants from cars, factories, and power plants. When air doesn’t move, those pollutants linger and accumulate, pushing ozone levels well above safe thresholds.
🩺 Health experts issue warnings
Professor Jonathan Grigg, a specialist in pediatric respiratory and environmental medicine at Queen Mary University of London, highlights that children are particularly vulnerable. Their developing lungs make them more susceptible to long-term harm from repeated exposure to high ozone levels.
Additionally, particulate pollution—often from smoke or traffic—has clear links to premature death from both cardiovascular and respiratory causes. Asthma flare-ups, reduced lung capacity, and increased hospital admissions have all been tied to episodes like today’s.
🌡️ Conditions may persist through the summer
Forecasters at AccuWeather expect that wildfire smoke and high ozone levels could remain a threat through August, with intermittent peaks depending on weather patterns, temperature surges, and wind conditions.
As of this morning, alerts are set to expire by midnight, but with wildfire activity continuing in Canada and hot conditions expected to persist, additional advisories could be issued in the coming days.
