Heat Advisory In Effect For LI Through Tuesday Night As Temps Spike

LONG ISLAND, NY — A blast of heat is expected to blanket Long Island through Tuesday night, the National Weather Service said.

According to Brian Ciemnecki, meteorologist for the NWS office in Upton, a heat advisory is in effect for all of Long Island, except parts of southeastern Suffolk County, through Tuesday night at 10 p.m.

Temperatures are slated to range from the upper 80s to lower 90s, with the heat index expected to make it feel more like 100 degrees or more, the NWS said. Some relief is expected Wednesday, with temperatures then expected to drop to the mid-80s Thursday.

A chance of isolated showers exists for Tuesday and Wednesday, with a better chance of showers and thunderstorms Wednesday and into Wednesday night, with the passage of a cold front through the area, Ciemnecki said.

According to the NWS, 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.

"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," the NWS said.

In addition, 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, dial 911, the NWS said.
