Heat Advisory issued June 22 at 3:11AM EDT until June 22 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...For the Heat Advisory, heat index values up to 99 expected. For the Extreme Heat Watch, dangerously hot conditions with heat index values up to 105 possible. * WHERE...In Connecticut, Southern Middlesex and Southern New London Counties. In New York, Northern Nassau, Northwest Suffolk, Southern Nassau, and Southwest Suffolk Counties. * WHEN...For the Heat Advisory, from noon today to 8 PM EDT this evening. For the Extreme Heat Watch, from Monday afternoon through Tuesday evening. * IMPACTS...Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities. Hot temperatures and high humidity may cause heat illnesses. * ADDITIONAL DETAILS...The highest heat index values will take place each day during the afternoon, especially on Monday and Tuesday.

An Extreme Heat Watch means that the combination of heat and humidity could create a dangerous situation in which heat illnesses are possible. 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. 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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
