Dangerous heat wave forecast for New York City, Tri-State area

NEW YORK (WABC) — A dangerous heat wave is forecast to unfold from the Midwest to the Northeast this week, bringing 90-degree weather to the New York City metropolitan area.

The National Weather Service has issued a hazardous weather advisory for southern Connecticut, Northeast New Jersey and southeast New York.

According to its most recent weather map, the NWS issued a hazardous weather outlook for southern Connecticut, northeast New Jersey and southeast New York.

A heat advisory will be in effect on Tuesday for parts of central New Jersey along the Interstate 95 corridor, while northern Connecticut is under an excessive heat watch for most of the week.

In our area, a heat wave is defined as a high temperature of 90 degrees or higher for at least three days.

While hazardous weather is not anticipated for Saturday, the weather service’s advisory remains in effect.

The Tri-State area could hit 90 degrees as early as Tuesday and exceed that benchmark at least through the first day of summer on Thursday.

Further south in places like Philadelphia and South Jersey, the streak of 90-degree days could extend for almost an entire week, according to the Eyewitness News AccuWeather team.

Rising humidity will make it feel several degrees hotter, with heat index values near 100 at times. Warm overnight temperatures only dropping into the 70s in some places will offer little to no relief.

Experts recommend avoiding outdoor activities during the afternoon and evening hours, which is usually the hottest part of the day. People who must be outside are encouraged to drink plenty of water and take breaks to cool off in the shade.

New York City last month announced a proactive safety plan to keep residents safe from extreme summer weather.

Each summer, an estimated 350 New Yorkers die prematurely due to heat and more Americans die from heat waves in a year than all other natural disasters combined, city officials said.

The city is trying to make it easier for New Yorkers to find cooling havens by updating its 24/7 Cool Options map, increasing cooling center partners, providing pet-friendly cooling centers, offering Cool Kits for vulnerable populations, distributing indoor thermometers and increasing heat preparedness messaging.

NYC OEM Commissioner Zach Iscol talks about the city’s preparations for summer heat.

In Connecticut, Governor Ned Lamont on Friday directed the state’s Extreme Hot Weather Protocol to be activated effective at 12:00 p.m. on Tuesday, June 18, 2024, and remaining in effect through 12:00 p.m. on Sunday, June 23, 2024. The protocol means he most vulnerable populations receive protection from the hot conditions. While enacted, a system is set up for state agencies, municipalities, and other partners to coordinate with United Way 2-1-1 to make sure that information regarding cooling centers is available statewide, providing a location to get some relief. Those locations can be found by calling 2-1-1 or visiting
