Persistent Smoke from Canadian Wildfires Affects Air Quality in South-Central Pennsylvania

The smoke from Canadian wildfires has worsened overnight in parts of south-central Pennsylvania, leading to unhealthy air quality. The region is currently under a code orange air quality alert, which may become unhealthy for sensitive groups such as children, asthma sufferers, and the elderly. The Pennsylvania Department of Environmental Protection may upgrade the alert to a Code Red later today. However, there is expected to be some improvement in air quality this afternoon and evening, with levels expected to improve to "moderate levels" over the weekend.
