New York City will be under a heat advisory starting Monday, but today is also sweltering.

The National Weather Service says temperatures could reach close to the high-90s over the next few days. The heat combined with high humidity can lead to illnesses like heat exhaustion or heat stroke, officials say.

New York City's Emergency Management Department recommends drinking lots of fluids and avoiding any heavy activity during the hottest parts of the day.

Those who don't have air conditioning can go to one of the cooling centers that the city has made available.
