Extreme Heat Warning and Air Quality Alert in Effect for Allegheny County

In addition, the Pennsylvania Department of Environmental Protection (DEP) has issued an Air Quality Action Day today. The combination of high temperatures, sunshine, and stagnant air will lead to ozone levels in the Code Orange range, meaning air quality is unhealthy for sensitive groups, including older adults, children, and people with respiratory issues. Conditions on Tuesday are expected to be similar and may result in continued air quality concerns. 

Heat and Air Quality Safety Tips: 

• Stay hydrated by drinking plenty of water throughout the day. Avoid alcohol and caffeinated beverages. 

• Limit outdoor activity, especially between 11 AM and 6 PM. Take frequent breaks in shaded or air-conditioned areas if you must be outside. 

• Use air conditioning or spend time in public spaces such as libraries, malls, or community centers if your home is not air-conditioned. 

• Keep phones and other devices charged in case of power outages due to heat-related strain on the power grid. 

• Never leave children or pets unattended in a vehicle, even for a short period of time. Temperatures inside cars can rise rapidly and become deadly. 

• Check on vulnerable individuals, including older adults, young children, and those with chronic health conditions. 

• Follow medical advice if you have asthma, COPD, or other respiratory conditions. Reduce prolonged or heavy exertion outdoors.
