Several regions across the United States, including Monmouth County, NJ, Pittsburgh, PA, Greater Cincinnati, OH, and Washington, D.C., are under Code Orange air quality alerts due to elevated ozone levels, posing health risks for sensitive groups like children, the elderly, and those with respiratory conditions. In Monmouth County, temperatures could reach near 100 degrees with sunny skies, while Pittsburgh and Greater Cincinnati are experiencing similarly high temperatures and humidity. Residents in affected areas are advised to limit outdoor activities, especially strenuous ones, and to take measures to reduce pollution, such as avoiding vehicle idling and conserving electricity. These conditions are expected to persist through mid-week, with some regions anticipating thunderstorms and slight cooling toward the end of the week.
