Philadelphia and Surrounding Areas See Gradual Air Quality Improvement Despite Lingering Smoke Threat.

The School District of Philadelphia has shifted to virtual learning on Friday due to poor air quality caused by smoky conditions from the Canadian wildfires. Air quality alerts are still in effect in Philadelphia and across the Delaware Valley, with a Code Red Air Quality Alert in effect for Delaware and a Code Orange Air Quality Alert in effect for Philadelphia and New Jersey. Health officials warn residents to pay attention to their bodies and seek medical attention if they experience trouble breathing, nausea, or dizziness. The smoke is also a threat to many animals, causing them to end up in unexpected places or even injured.
