CODE RED: Air quality concerns linger due to Canadian wildfire smoke

PITTSBURGH — Air quality will once again be a huge issue for much of the area Thursday with levels high enough to make prolonged outdoor activities difficult for some people. A Code Red Air Quality alert is in effect with the worst conditions expected during the morning hour as smoke from Canadian wildfires will bring unhealthy air quality conditions.

An atmospheric “inversion” will trap smoke and fog near the surface, reducing visibility and creating a rough start to the day. Light winds will keep a smoky haze in the air through the afternoon.

What’s that smell? Smoke from Canadian wildfires emitting particular scent

Outdoor activities are not recommended, especially for young children and those with respiratory ailments. Please be smart and pay attention to your body if you are outdoors.

The Pirates delayed its 12:35 p.m. game at PNC Park as they considered the air quality. Shortly after, the team announced they’re moving forward with the game with a new start time of 1:20 p.m.

All City of Pittsburgh pools are also closed for the second day in a row.

The next weather maker will bring air quality improvements Friday but also increase the threat for thunderstorms. Strong to severe storms with damaging winds will be possible late Friday and early Saturday.
