“The wildfire smoke will remain in the area this afternoon but is expected to eventually move out of the area on Saturday,” the health department said.

EXPLAINER: What is Code Maroon air quality?

The U.S. EPA, DEP, and Allegheny County Health Department recommend the following guidance under Code Maroon:

Everyone: Avoid all physical activity outdoors

Sensitive groups: Remain indoors and keep activity levels low. Follow tips for keeping particle levels low indoors

If you don’t have an air conditioner, staying inside with the windows closed may be dangerous in extremely hot weather. If you are hot, go someplace with air conditioning or check with your local municipality to find out if cooling centers are available in your community.

HOT AND HUMID IN PITTSBURGH REGION

On top of the dangerous air quality, Thursday is another hot and humid day in Western Pennsylvania.

The Pittsburgh’s Action Weather forecast calls for high temperatures near 90 degrees through Friday, and feels-like temperatures in the mid 90s when combining temperature with humidity.

It appears that our air quality will not improve until late Friday or early Saturday. Because of that, Friday will be another Severe Weather Alert Day.

AIR QUALITY CONCERNS

The Associated Press reports that more than 100 wildfires are burning in Canada and winds are carrying the smoke southeast. Warnings about unhealthy air conditions extended from Minnesota through Toronto and into New York.

High levels of fine particulate matter in the air from wildfire smoke may be unhealthy for sensitive groups, such as children and people with heart or lung conditions. The particulates can cause shortness of breath, coughing, dizziness or fatigue and aggravate heart and lung diseases and other chronic health issues.

Experts suggest wearing a N95 mask if you have to be outside and keeping your indoor air cleaner by closing windows and running an air purifier or air conditioner.
