Individuals with respiratory conditions or sensitivities to PM2.5 may experience mild to moderate symptoms, such as eye, nose, or throat irritation. Long-term exposure to PM2.5 can aggravate chronic heart and lung diseases. While pollen levels are not extreme, those with allergies to elm, ash, or birch trees should remain cautious. The heat index of 88°F (31.1°C) may also pose minor risks for heat-sensitive individuals.
