The National Weather Service has issued a Heat Advisory for New York on Wednesday, with temperatures expected to reach into the 90s.

A Heat Advisory is triggered when the combination of heat and humidity is anticipated to make it feel like 95 to 99 degrees for two or more consecutive days, or 100 to 104 degrees at any time.

The advisory is in effect from 11 a.m. until 8 p.m. Wednesday.

According to NY1 meteorologist Guy Brown, the heat index is expected to reach into the triple digits.

There will be some shower chances, and the heat should decrease by Thursday, said Brown. There is also a small shower chance for Friday.

Cooling centers throughout the city will remain open through Wednesday in preparation for the high heat.

Officials urge residents without access to air conditioning - especially senior citizens - to utilize these facilities, some of which are pet-friendly. Find one here.

The New York City Office of Emergency Management has also provided a map of outdoor cooling options, including spray showers, drinking fountains, and tree cover here. The map also details which parts of the city are the most vulnerable to extreme heat.

As temperatures climb, New Yorkers are advised to remain vigilant for symptoms of heat stroke, including hot and dry skin, elevated heart rate, confusion and nausea.
