Eastern Suffolk is no longer under a heat advisory, the NWS said.

Temperatures Monday are expected to hit the upper 80s to near 90s, the NWS said, with a heat index making it feel as though its between 95 degrees and 100 degrees.

In eastern Suffolk, it will feel as though it's in the low 90s, the NWS said.

Hot temperatures and high humidity may cause heat illnesses, the NWS said.

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 NWS said.

Seniors and those with chronic health problems or mental health conditions are at an increased risk, the NWS said.

Homes without air conditioning can be much hotter than outdoor temperatures; residents should use air conditioning to stay cool at home or go to a place that has air conditioning, the NWS said.

Those without home air conditioning are advised to continue to seek out cool spaces each day as long as it remains hot, and for a few days after homes are still hot, the NWS said.

Residents should also check on vulnerable friends, family members and neighbors, the NWS said.

To reduce risk during outdoor work, the Occupational Safety and Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments, the NWS said.

Anyone overcome by heat should be moved to a cool and shaded location, the NWS said.

"Heat stroke is an emergency! In cases of heat stroke call 911," the NWS said.
