Warnings and alerts have been issued due to the high temperatures, heat indexes and air pollution in the county and surrounding area — and the hot weather isn’t going away yet.

The National Weather Service and the Pennsylvania Department of Environmental Protection issued warnings and alerts Monday, June 23, as the temperature reached 94, humidity pushed the heat index to 100 or more and air pollution reached levels that may be unhealthy for children, elderly and people with health problems.

An extreme heat warning from the weather service remains in effect until 8 p.m. Wednesday, while the DEP’s code orange air quality action days for ozone were only issued for Sunday and Monday.

High pressure that moved into the area over the weekend has brought high temperatures and humidity, said Liana Lupo, a meteorologist with the National Weather Service in Pittsburgh.

Tuesday’s forecast predicts another day of 94-degree temperatures and a heat index of 100, but the extreme heat warning said the heat index could reach 105 through Wednesday.

The heat index reflects humidity, which makes the temperature feel hotter to people.

“In the desert, 100 feels like 100 due to the dryness. Humidity makes it feel hotter,” Lupo said.

The weather service recommends drinking plenty of fluids, staying in an air-conditioned rooms, staying out of the sun, and checking up on relatives and neighbors.

For people who work outdoors, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments, according to the weather service.

According to the DEP, a code orange air quality alert means that air pollution concentrations may become unhealthy for sensitive people such as children, the elderly and people suffering from asthma, heart disease or other lung diseases. The effects of air pollution can be minimized by avoiding outdoor exercise or strenuous activity.

Alameda Waterpark has been the destination for resident looking for a fun way to cool down.

“The waterpark was very busy on Saturday and Sunday. They were probably two of our busiest days of the 2025 season to this point,” said Lance Welliver, county parks and recreation director. “With the current temperatures, I would anticipate it to be very busy at the waterpark for most of the week.”

The county emergency services department hasn’t been asked to set up a cooling station, but it is prepared to work with the Red Cross to do so if the need arises, said director Steve Bicehouse.

“We encourage people who need relief to utilize public areas with air conditioning, such as stores, malls,” Bicehouse said.
