Mayor Eric Adams held a news conference Saturday to urge New Yorkers to take precautions ahead of the extreme heat.

Adams also advised the public to stay hydrated, take advantage of the city's cooling centers and other resources as temperatures rise this weekend.

Adams also warned the heat "could be one of the most deadly weather conditions" that the city could experience.

"Each year, we see more than 500 New Yorkers die because of hot weather, so it's imperative to prepare ourselves," Adams stressed.

Adams warned that the first potential heat wave of the year and the extreme heat will not only be uncomfortable but oppressive and dangerous if New Yorkers do not heed the warnings from officials.

He said the National Weather Service issued an extreme heat warning for New York City, effective Sunday through Tuesday.

Adams warned the next days will see high heat and humidity, with temperatures in the upper 90s. The peak heat on Tuesday could possibly reach 100 degrees. He urged New Yorkers to use air conditioning in a moderate manner.

Adams said the city will open cooling centers and urged New Yorkers to either take advantage of them or to stay with family members who have air conditioning in their homes.

He added that libraries or museums can also serve as city cooling centers. New Yorkers can find them at nyc.gov/beattheheat or call 311.

Adams also advised those who work outside to take plenty of breaks, drink water and stay in the shade.

The mayor urged New Yorkers to never leave children or pets in parked cars, as it could be extremely dangerous under the heat.

Adams said the city will be in constant communication with PSEG and Con Edison to monitor the electrical system to ensure that power outages are minimal. He said the system can be stressed when temperatures rise to high levels and when New Yorkers have air conditioning at higher levels than necessary.

Adams also said New Yorkers can sign up at Notify NYC, the city's free emergency notification system for updates about weather and air quality issues.
