Yellow / "Moderate": Limit outdoor activities during times of smoke, especially for persons with lung conditions, such as asthma. People should consider leaving the area if smoke levels are hazardous and they have heart disease, asthma and other respiratory conditions. Individuals may experience symptoms such as increased coughing, throat irritation, headaches or shortness of breath.
