Scorching Temperatures Threaten NYC Later This Week, Forecasters Warn

NEW YORK CITY —Friday is expected to have dangerous triple-digit heat indexes and humidity, due to a heat dome from the Midwest moving east, Forecasters warned on Wednesday.

The National Weather Service issued a Heat Advisory for all five boroughs on Friday between 11 a.m. and 8 p.m.

Friday will have a temperature high of 95 degrees, but heat index values of up to 105 degrees during the day are expected, forecasters said. Some scattered rain is also expected on Friday, but it won't put a damper on the heat, meteorologists 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, according to the National Weather Service.

The lows at night are in the high 70s, and may not offer much relief with high humidity persisting.

It is important to take precautions during the day on Friday, especially for those with chronic health problems and those who are working outside, National Weather Service forecasters said.

Homes without air conditioning can be much hotter than outdoor temperatures, so use air conditioning to stay cool at home or go to a place with air conditioning, like one of the city's Cooling Centers, officials said.
