Smoke from hundreds of wildfires in Canada is lingering over the northern U.S., spreading across to roughly a dozen states from Wisconsin to Maine.

Southern Vermont & Upper Valley: As a bulk of the local wildfire smoke shifts south, it’s southern Vermont/New Hampshire and the Upper Valley that will see the poorest of air quality. Air Quality Alerts have been issued for our southern Vermont and Upper Valley friends as the AQI will land in the “Unhealthy for sensitive groups” category today.

An air quality alert from Canadian wildfire smoke will last through the day Wednesday, according to Vermont Emergency Management
