Heat Advisory issued July 15 at 2:14PM EDT until July 17 at 10:00PM EDT by NWS Upton NY

Effective: Tue July 15, 2025, 2:14 PM
Expires: Wed July 16, 2025, 5:00 AM

* WHAT...Heat index values up to 102 expected. * WHERE...Portions of southern Connecticut, northeast New Jersey, and southeast New York. * WHEN...From 11 AM Wednesday to 10 PM EDT Thursday. The highest heat index values will occur during the afternoon each day. * IMPACTS...Hot temperatures and high humidity may cause heat illnesses.

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. 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.

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.
