After a few days of cooler weather, the heat and humidity are set to return, prompting city officials to declare a heat advisory for Friday. The advisory runs from 11 a.m. to 8 p.m. as daytime temperatures are expected to reach the mid-90s.

With a heat advisory in effect for much of the day, New Yorkers should consider limiting any strenuous activity outside. The National Weather Service (NWS) warns that these conditions lead to an increased risk of heat-related illnesses, like heat stroke.
