Torrington, Conn. – Residents across Litchfield County should limit outdoor activity Wednesday as unhealthy levels of ground-level ozone are expected between 11 a.m. and 11 p.m.
According to the Connecticut Department of Environmental Protection, an Air Quality Action Day has been issued for both Northern and Southern Litchfield. Cities including Torrington, New Milford, and Thomaston are likely to see ozone concentrations rise to levels that may pose health risks—especially for children, seniors, and individuals with asthma or respiratory issues.
The alert is tied to hot, stagnant air and vehicle emissions combining under sunny skies—conditions that typically trigger summer ozone spikes in the region. Sensitive groups are advised to stay indoors during peak afternoon hours, reduce strenuous activity, and use air conditioning with clean filters if available.
Drivers can help lower emissions by postponing unnecessary trips or refueling after sunset. Schools and day camps in affected areas may want to limit outdoor play.
Ozone levels are expected to drop after sunset Wednesday, but similar conditions could return later this week. The Connecticut Air Quality Index at ct.gov/deep/aqi will provide real-time updates.
