All of New York state will be feeling the heat on Thursday and Friday, Governor Kathy Hochul warned as she spoke in Oswego, in central New York, on Wednesday.

The “real feel of temperature” in New York City, Long Island, and the Mid-Hudson area is expected to be over 105, she said.

“This is extreme even for some of the parts of our country where we’re seeing these numbers, but for New York state, this is highly unusual,” said Hochul. “And at this time, we’re putting out heat advisories that’ll be in effect all the way through Friday night.

“It won't be quite as bad here in Upstate New York, but we expect to see temperatures exceeding over 90 degrees. And the real feel on your skin, for your body, it’s going to feel over 95 degrees.”

Older adults and individuals with chronic diseases are most vulnerable to heat-related illnesses, says the state’s website. Factors such as obesity, fever, dehydration, prescription drug use, heart disease, mental illness, poor circulation, sunburn, alcohol use, outdoor work, and living in urban areas where pollution may linger on hot days can increase the risk of heat-related illnesses.

Signs of heat-related illnesses such as heat stroke and heat exhaustion include high body temperatures (103 degrees or higher); hot, red, dry, or clammy skin; fast, strong pulse or a fast, weak pulse; headache, dizziness, nausea, vomiting, tiredness or weakness; muscle cramps or spasms and losing consciousness, passing out, and fainting.

“If these symptoms are evident,” the post advises, “call 9-1-1, move the person to a cool place, loosen clothing, and put cool wet cloths on their body or get them into a cool bath.”

“We want to make sure people know that our state agencies are preparing to respond, provide resources,” said Hochul. “But here’s what we can do individually. Stay indoors between the hours of 11 and four, hopefully in an air-conditioned setting. Avoid the sun overall.

“If you have to be outside, wear plenty of sunscreen. Hydrate. Have water with you. Have water in your car, have water if you’re walking down the street or going to the park. Something that might be a normal activity could be strenuous for you under these extreme temperatures.”

She also advised, “Never leave your children or your pets in a car. We have too many tragedies where people think they’re just going to run into a store and be out momentarily. They get detained, and all of a sudden there’s devastating consequences. Temperature can become very dangerous very quickly.”

Hochul advised New Yorkers without air-conditioning to use cooling centers. Locally, the public libraries in Guilderland, Bethlehem, and Voorheesville are air-conditioned.

Also, on Wednesday evening, the governor’s office sent out a list of state parks that are extending hours during the heatwave including Thompson’s Lake Campground at Thacher State Park, which will allow swimming till 7 p.m. on both Thursday and Friday.
