Alerts issued for air quality, high temperatures across Pittsburgh region

Authorities have issued advisories for air quality and high temperatures Thursday in Southwestern Pennsylvania.

Smoke from Canadian wildfires is the primary reason for the National Weather Service issuing an air quality notice.

While the smoke has recently been at high levels in the atmosphere, causing hazy skies, an inversion will keep the smoke closer to the surface on Thursday, a meteorologist said.

The alert covers Armstrong, Allegheny, Beaver, Butler, Fayette, Washington and Westmoreland counties.

Sensitive groups including seniors, children and those with compromised immune systems should take care by avoiding outdoor exercise or strenuous activity, the weather service says.

However, poor air quality can be hazardous to anyone and it can aggravate health problems such as asthma, heart disease and lung disease.

The region will also be seeing a brief warmup, with highs Thursday afternoon approaching 90 in spots, according to the weather service.

That has prompted Allegheny County Emergency Services to remind residents to stay safe in the heat.

While not considered extreme heat, prolonged exposure to sun and high temperatures can still lead to heat-related illnesses especially for children, older adults and those with underlying health conditions, the county said.

Heat safety tips include: drinking plenty of water throughout the day, even if not thirsty; scheduling errands, work or exercise for early morning or early evening hours; using shaded areas or air conditioned spaces to cool down regularly; limiting alcohol, which can increase dehydration and impact the body’s ability to regulate temperature; wearing light, loose-fitting clothing, sun protection and sturdy shoes; checking on others especially the elderly; never leaving children or pets in vehicles; and watching for signs of stress including dizziness, weakness, nausea or confusion and seeking help if symptoms arise.

For those attending the U.S. Open at Oakmont Country Club, hydration and first aid stations are available throughout the course.

“Whether you’re outside at home or attending the U.S. Open at Oakmont Country Club, it’s important to take care in the heat,” emergency services Chief Matt Brown said. “Stay hydrated, take breaks in the shade or air conditioning, and check on those who may need assistance.”
