A heat and air quality advisory is in effect for Westchester County.
The National Weather Service issued the warning on Wednesday morning, warning that heat and humidity could make outdoor temperatures feel like 100 degrees or hotter through Thursday night.
At the same time, the New York State Department of Environmental Conservation has rated the air quality as unhealthy for sensitive groups due to elevated ozone levels through 11 p.m. Wednesday night.
The Air Quality Index is expected to exceed 100, meaning those in sensitive groups, including children, older adults, people with asthma or heart conditions, and those who work or exercise outdoors, may experience health effects. Symptoms can include coughing, shortness of breath, and irritation to the eyes, nose, or throat.
County health officials advise limiting outdoor activity and spending time in air-conditioned spaces.
“Please pace yourself—the heat and humidity can take a lot out of you,” said Westchester County Health Commissioner Dr. Sherlita Amler. “Drink lots of water, take frequent breaks, and don’t overdo it.”
City residents can find a cooling center at the Rye Free Reading Room, located at 1061 Boston Post Road, from 9:30 a.m. to 8 p.m. on Wednesday and Thursday.
