STATEN ISLAND, N.Y. -- Most of the country is expected to be hit with extremely high temperatures this weekend, and New York City is no exception -- with temperatures expected to hit the high 90s, with a heat index over 100 degrees -- causing an excessive heat watch to be issued throughout the five boroughs for the weekend.

The excessive heat watch is from noon Friday to 10 p.m. Saturday, according to AccuWeather.com.

An excessive heat watch means that the combination of heat and humidity could create a dangerous situation in which heat illnesses are possible.

Temperatures are set to hit 90 degrees on Friday, and Saturday’s forecast calls for a high temperature of 97 degrees, although it will feel more like 107, according to AccuWeather.com. And the heat is expected through Sunday.

“New York City is expecting extremely dangerous heat this weekend, and we want to advise New Yorkers to prepare for the intense temperatures. Use air-conditioning or go to one of the City’s cooling centers to beat the heat, and stay out of the sun as much as possible,” said New York City Emergency Management Commissioner Deanne Criswell in a press release.

COOLING OFF

The city’s cooling centers will remain open through Sunday. Cooling centers are air-conditioned facilities such as libraries, community centers, senior centers, and NYCHA facilities that are open to the public during heat emergencies.

To find a cooling center, call 311, or visit the NYC Cooling Center Finder at NYC.gov/beattheheat.

In addition, the city’s pools will have extended hours this weekend.

Outdoor pool hours at the Island’s Olympic- and intermediate-sized pools -- Faber Pool, Lyons Pool, Tottenville Pool and the West Brighton Pool -- are extended to 8 p.m. from Friday, July 19, through Sunday, July 21, according to the Parks Department.

Traditionally, outdoor pool hours are from 11 a.m. to 7 p.m., seven days a week. There is a break for pool cleaning from 3 to 4 p.m. daily.

The city’s beaches are also open. Lifeguards are on duty daily from 10 a.m. to 6 p.m. Swimming is prohibited when lifeguards are not on duty and in closed sections marked with signs and/or red flags.

The city operates spray showers in playgrounds and parks across the city, with over 25 on Staten Island. In general, spray showers operate on days when the temperature hits 80 degrees or higher.
