BROOKLYN - With New York City being in a heat advisory until 5:00 p.m. today, the city has opened cooling centers across the five boroughs.

Places like libraries, community centers and senior centers are some of the places being used as cooling centers.

Mayor Bill de Blasio visited a cooling center in the Bronx on Thursday and urged New Yorkers to stay hydrated and stay indoors or head to one of the air-conditioned public spaces. 

With more heat expected, the city is also offering refuge to single adults at any homeless shelter and extending swimming hours at public pools.
