The air quality in Philadelphia has dropped to "unhealthy" levels for all residents as smoke from wildfires in Canada continues to move into the area. Philadelphia, along with the entire state of Pennsylvania, remains under a "code red" air quality alert. Delaware has also issued a "code red" alert, and New Jersey is under a "code orange" alert. The air quality index in Philadelphia reached 180, classified as "unhealthy" for all. As a result, city pools will be closed and summer camps run by the city will be moved indoors. The Philadelphia Department of Health advises residents to cancel outdoor events and gatherings and to close all windows and doors to minimize air pollution in the home. If residents must go outdoors, wearing a high-quality mask and avoiding areas of high congestion, such as main streets or highways, is recommended. Poor air quality in Philadelphia is expected to persist into Friday.
