The hot and humid weather on Long Island will continue Thursday, with a heat advisory in effect for parts of the region.

A heat advisory is in effect for Nassau County and New York City until 6 p.m. Thursday, as the steam-bath conditions are expected to continue.

The forecast for Thursday, as of Wednesday evening, was for high temperatures around 90 degrees, feeling more like the mid-90s thanks to the humidity.

It’s not out of the question that higher moisture levels in the air, as determined early Friday, could push the heat index — or “feels-like” temperature — a couple of degrees higher, said Tim Morrin, National Weather Service meteorologist in Upton.

A heat advisory can be issued when the combination of heat and humidity is expected to make it feel like it is 95 to 99 degrees for two or more consecutive days.

In response, cooling centers are being opened in multiple Nassau County locations through Friday, according to a news release from the county executive’s office.

County locations open from 10 a.m. to 6 p.m. are: Mitchel Field Complex, Uniondale; Wantagh Park Community Center, Wantagh; Grant Park, Hewlett. Centers offered by the Town of Oyster Bay are: Bethpage Ice Center, Bethpage; Syosset-Woodbury Ice Rink, Woodbury; Marjorie Post Rink, Massapequa.

An air quality alert was also issued for Thursday from 11 a.m. to 11 p.m., indicating elevated levels of ozone, which can be a health concern. Those who may be especially sensitive to poor air quality include the very young and people with pre-existing respiratory issues, including asthma and heart disease.

“Hot and humid weather going into the weekend,” with above normal temperatures, said Rich Hoffman, News 12 Long Island meteorologist. “Good beach weather the next few days.”
