Heat Advisory In Effect For Parts Of Long Island Tuesday Into Wednesday: NWS

LONG ISLAND, NY — A heat advisory is in effect for parts of Long Island Tuesday into Wednesday, according to the National Weather Service.

The heat advisory has so far been issued for northwest Suffolk County and all of Nassau County, from noon Tuesday until 9 p.m. Wednesday.

Heat index values up to 101 degrees are expected, with the highest heat index values on Wednesday, the NWS said.

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, the NWS said.

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, the NWS said.

The NWS advises individuals to use air conditioning to stay cool at home or go to a place that has air conditioning; residents without home air conditioning should continue to seek out cool spaces each day as long as it remains hot, and for a few days after if homes are still hot.

"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. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency! In cases of heat stroke call 911."

Temperatures across the East End are slated to reach the high 80s Tuesday and Wednesday, the NWS said.
