NEW YORK (WABC) -- Dangerously hot temperatures were gripping New York City and the Tri-State area again on Wednesday, the final day of the heat wave.

On Thursday, there will be relief as temperatures tumble by 20 to 25 degrees.

The National Weather Service issued a Heat Advisory for the Tri-State area for Wednesday. A Heat Advisory is 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, or 100 to 104 degrees for any length of time.

Seniors and those with chronic health problems or mental health conditions are at an increased risk. Homes without air conditioning can be much hotter than outdoor temperatures.

Tuesday was a record-breaking day with the official temperature in New York City reaching 99 degrees in Central Park just before 4 p.m., breaking the record set in 1888 and the hottest day since July 18, 2012.

The temperature at Kennedy Airport reached 102. That was a new daily record for this date, but it is also the hottest June temperature on record at the airport.

Newark, New Jersey hit a record high of 103 degrees, breaking the old mark of 97 set in 1966 and tying its hottest June temperature on record. The city also hit 103 in June 2021.

The high temperature in Islip, New York on Tuesday was 101, breaking the daily record for the day and setting a new June monthly record. Records for the Islip area go back to 1963. The previous hottest June temperature on record for Islip was 96 degrees set in 1966 and 1994.

Con Edison asks customers on Manhattan's East Side to conserve energy

Con Edison is asking some of its customers on the East Side of Manhattan to conserve energy while company crews repair equipment. Con Edison says it has reduced voltage by 8% in the area to protect equipment and maintain service as crews make repairs.

The impacted area is bounded by East 111thStreet on the north, East 77thStreet on the south, the East River on the east, and Fifth Avenue on the west. Con Ed says the area includes 87,700 customers in parts, or all, of these neighborhoods: the Upper East Side, Yorkville, East Harlem and Carnegie Hill.

The company says the equipment problems in these neighborhoods have no effect on the rest of the Con Edison system.

New Yorkers struggle to stay cool

The city has what's called a Heat Vulnerability Index that ranks neighborhoods from one to five, with five being the worst.

Harlem is the only neighborhood in Manhattan that's ranked as five.

Emergency Management officials said 112 New Yorkers went to the ER Tuesday for heat-related illness.

But there is some some good news: city pools will open on Friday. The weather will have cooled off a little bit by then but that will be a great way to stay cool.

Con Edison information

Customers can report outages and check service restoration status at www.conEd.com/reportoutage, or with the ConEd mobile app for iOS or Android devices, or by calling 1-800-75-CONED (1-800-752-6633). When calling, customers should report whether their neighbors also have lost power.

Medical expert speaks on challenges for outdoor workers

Doctors on Long Island said they had a spike in ER visits starting Monday.

Most of those visits included more vulnerable people, like the elderly, but those who needed to be admitted tended to be the younger workers who were needed outdoors.

"They're at risk too, and we don't think of them as vulnerable because being not at extremes of ages, but because of the nature of their jobs and activities, that makes them high risk," said Dr. Payal Sud with North Shore University Hospital.

That applies to those working jobs like brick laying, landscaping and even maintaining the power grid.

Stacey Sager reports from Roslyn, Nassau County, with reaction from people working outside in the oppressive heat.

"We don't want our customers to be without power in extreme heat so we work our employees around the clock," said Larry Torres with PSE&G Emergency Preparedness.

Those who must work outside are encouraged to take frequent breaks, stay out of the sun, and drink plenty of water.

NJ highway buckles in the extreme heat

I-287 southbound has lane closures in two locations due to emergency roadway repairs in Riverdale and Montville, Morris County. In both locations, the expansion of bridge joints caused the concrete roadway to buckle.

Crews will continue to make repairs to the damaged roadway. It is unclear how long repairs may take at this time. Motorists are advised to use caution, slow down, move over, and expect delays.

Heat impacts graduation ceremonies in New Jersey

The extreme heat took its toll at outdoor graduation ceremonies in Paterson.

During a morning ceremony at Hinchcliffe stadium, 59 people were treated for heat-related issues and nine were taken to the hospital.

Then, so many more people had issues at the afternoon graduation that it was canceled. That included 107 people treated for issues with seven taken to the hospital.

Families are upset the district didn't better prepare for the heat that everyone knew was coming.

Some schools, like in Newark, had early dismissals Tuesday and will have early dismissals again on Wednesday.
