Extreme Heat Warning issued June 22 at 3:11AM EDT until June 24 at 8:00PM EDT by NWS Upton NY
Effective: Sun June 22, 2025, 3:11 AM
Expires: Sun June 22, 2025, 4:00 PM
* WHAT...Dangerously hot conditions with heat index values up to 107 expected. * WHERE...Bronx, Kings (Brooklyn), New York (Manhattan), Northern Queens, Richmond (Staten Island), and Southern Queens Counties. * WHEN...From noon today to 8 PM EDT Tuesday. * IMPACTS...Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities. * ADDITIONAL DETAILS...The highest heat index values will take place each day during the afternoon, especially on Monday and Tuesday.
New York City residents should call 3 1 1 to identify cooling center locations and obtain 'Beat the Heat' safety tips. An Extreme Heat Warning means that the combination of heat and humidity is expected to make it feel like it is 105 degrees or greater. Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible, and drink plenty of water. 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. Use air conditioning to stay cool at home or go to a place that has air conditioning. If you don't have home air conditioning, continue to seek out cool spaces each day as long as it remains hot, and for a few days after if your home is still hot. Check on vulnerable friends, family members and neighbors. To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! In cases of heat stroke call 9 1 1.
