WHAT...The PM2.5 AQI is expected to reach the Unhealthy for Sensitive Groups to Unhealthy level. WHERE...All of Wisconsin WHEN...Until noon Monday, August 4 Precautionary/Preparedness Actions: Sensitive groups: Consider rescheduling or moving all activities inside. Go inside if you have symptoms. People with asthma: Follow your asthma action plan and keep quick-relief medicine handy. People with heart disease: Symptoms such as palpitations, shortness of breath, or unusual fatigue may indicate a serious problem. If you have any of these, contact your health care provider. Everyone else: Keep outdoor activities shorter and less intense. Go inside if you have symptoms. Additional Details: Canadian wildfire smoke will continue to impact Wisconsin surface air quality. A mix of Unhealthy for Sensitive Groups (USG; Orange) AQI and Unhealthy (Red) AQI is forecast again today as smoke persists over the region and continues to recirculate around a slowly moving surface high pressure system. The heaviest smoke is expected across eastern Wisconsin today, while lighter impacts are more likely for western counties. A few locations may observe Moderate (Yellow) AQI, especially to the west. Conditions will continue to be reevaluated on a day-to-day basis, including updates to the forecast and any associated Air Quality Advisories.
