An extreme heat warning is now in effect in New York City, with temperatures expected to top 100 degrees in the days ahead.

The National Weather Service has called an extreme heat warning across the five boroughs, starting early Sunday — just two days after the first day of summer — and lasting until at least 8 p.m. Tuesday.

The forecast predicts “dangerously hot conditions with heat index values up to 107 expected,” with the worst of the heat hitting in the afternoon Monday and Tuesday.

Central Park last had a 100-degree day on July 18, 2012, and hasn’t seen a triple-digit temperature in June since 1952.

“Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities,” the warning reads.

The heat wave can be blamed on “a strong bubble of high pressure,” or a “heat dome,” expected to envelop much of the eastern U.S., according to the Weather Channel. That bubble prevents clouds from forming, meaning no rain, intense sunshine and wretched humidity.

The city is making cooling centers available and their locations — along with tips to handle the heat — can be found at nyc.gov/beattheheat.

The city Parks Department’s “Cool It! NYC” web page also offers a map of swimming pools, spray showers, drinking fountains and shady spots.
