Wildfire smoke will sweep back into Vermont on Thursday, prompting an Air Quality Alert covering the southern half of the state from 6 a.m. to 11 p.m., officials said Wednesday.
The alert, announced by WCAX's First Alert Weather Team, warns that air quality could reach unhealthy levels for people who are sensitive to smoke. Central and southern Vermont are expected to experience the thickest smoke and haze, while northern counties should see improvements later in the day as a cold front moves through.
What to expect Thursday
After a brief window of cleaner air and brighter skies Wednesday evening, thicker wildfire smoke will return by Thursday morning. Residents can expect:
- Thick smoke and reduced visibility across much of Vermont;
- Worst conditions in central and southern areas through early evening;
- Improvement from north to south as a cold frontal passage clears smoke in the afternoon and evening;
- Possible showers or thunderstorms with the front, though severe weather risk is low.
| Timing | Area | Expected conditions |
|---|---|---|
| Thursday morning–early evening | Central & southern Vermont | Thick smoke; poorest air quality |
| Late afternoon–evening | Northern Vermont & North Country | Improvement as cold front passes |
| Friday morning | Statewide | Air quality expected to be better |
Health guidance and practical steps
WCAX noted that people with pre-existing heart or lung conditions, young children and older adults face the greatest risk from smoke inhalation. Officials advise limiting or avoiding strenuous outdoor activities if you are sensitive to smoke.
Simple precautions residents can take include:
- Keeping windows and doors closed when smoke is heavy;
- Running air conditioning on recirculate if available and using higher-efficiency filters;
- Postponing outdoor exercise and strenuous work during the worst hours;
- Using an approved respirator (N95 or equivalent) if extended outdoor exposure is unavoidable.
The First Alert Weather Team cautioned that smoke aloft and near the ground will make skies appear milky or gray and could produce sepia-toned sunrises and sunsets where smoke is thickest.
Forecasts indicate the situation will likely be intermittent while wildfires in the broader region remain uncontrolled. Residents should monitor local air quality updates and forecasts for changing conditions.
