Temperatures Soar Into 90s Again Thursday For Hottest Day Of 2017

NEW YORK (CBSNewYork) -- A heat advisory was in effect for much of the Tri-State area Thursday as temperatures climb once again into the 90s.

In fact, it turned out to be the hottest day of 2017.

The heat advisory was in effect until 8 p.m. in New York City, as the humidity made it feel like it's in the mid 90s to around 100 degrees in some spots. An air quality alert was also in effect.

In White Plains, many were hitting the pool early Thursday.

"It's hot, hotter than hot," Linda Iarocci told CBS2's Vanessa Murdock. "You gotta be in the pool. You gotta stay cool and we're here."

Nine-year-old Sebastian Gonzalez thought the water would be cool.

"The pool is nice and warm," he said. "It's usually cold, but there's a big sun today so it's warm."

His father, Dante Gonzalez, found the perfect spot to spectate: the shade.

"I'm about to jump in in a little bit, so I'm going to have my time," he said.

Macayla Patterson was celebrating her 13th birthday.

"It's nice and sunny, so it's pretty good to go to the pool," she said. 

Tyeema Barner said she kept her kids home from camp because of the extreme heat.

"It's hot if you run around in the sun, and you almost pass out," she said.

Jackie Longo was hoping to find a break from the heat on the sands of Harbor Island in Mamaroneck, wearing sunscreen, sunglasses and a hat.

"Just go in there, get water under the sprinklers and come out – that's all you need to do," she said.

No such luck though for the Rodrigues family. After 30 minutes of playing in the sprinklers they had to head home.

"It's just too hot today, we need to get away," Mary Rodrigues said.

Gov. Andrew Cuomo extended state pool and beach hours in several locations. 

Meanwhile, the hot weather has the city sweltering and feeling sticky.

"It's terrible," Harlem resident Keran Barran told CBS2's Janelle Burrell. "Too humid, too hot. I can't stand it."

"It's very, very hot," said Brooklyn resident Ruben Matayev.

"You walk and you're out too long, you feel dirty," said Staten Island resident Haley Morton.

And underground, the subway is feeling like a sauna.

"It gets too hot down there," said commuter Andrew Gorab, who won't even venture down to the platform until the train arrives. "I give myself a minute before the train comes."

One man stood on the platform in a suit.

"I don't know how I can do it, but I'm doing it," he said. "It's a challenge, but Italians always rise to the challenge."

It also feels miserable on the blacktop, where worker Tye Varlack is determined to stop the sweat in its tracks.

"It's very hot, very hot," he said. "You don't want to be out here if you don't have to."

"I've been out here all week," he added. "I'm just trying to keep hydrated and stay out the sun."

Inside the kitchen at Cranberries deli, James Monamoreno said "it's like a sauna."

"Four-hundred degree oven plus 93 percent humidity and however hot it is outside – it's brutal," he told WCBS 880's Mike Sugerman.

Health professionals say it's easy to suffer from heat exhaustion in these conditions.

"Increasing your fluid intake on a daily basis is very important as well as throughout the day," said Dr.

Lawrence Phillips, a cardiologist with NYU Langone Medical Center.

The warning signs include nausea, heart palpitations or fluttering in your chest, shallow breathing and changes in sweating like if you go from heavy sweating to not sweating at all.

"That means your body has gone beyond its reaction and it's in survival mode," Dr. Phillips said.

Friday is expected to be another hot and humid day with highs around 90.
