* WHAT...For the Extreme Heat Warning, dangerously hot conditions with heat index values up to 113. For the Extreme Heat Watch, dangerously hot conditions with heat index values up to 103 possible. * WHERE...Portions of southern Connecticut, northeast New Jersey, and southeast New York. * WHEN...For the Extreme Heat Warning, until 9 PM EDT Friday. For the Extreme Heat Watch, from Friday evening through Saturday evening. * IMPACTS...Extreme heat and humidity will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities.

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

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.
