A heat advisory will continue to be in place in Brooklyn through 8 p.m. Wednesday.

It comes as the borough is experiencing its second heat wave of the summer. The National Weather Service says Monday was the hottest day of the year so far.

As a result, New York City Emergency Management says cooling centers are open again. They include places like senior centers and public libraries.

To find the closest cooling center to you, you can either call 311 or visit the cooling center finder here.

With temperatures reaching the 90s, it's also important to be aware of the symptoms of both heat exhaustion and heat stroke.

Heat exhaustion typically presents with dizziness, thirst, heavy sweating, and nausea. In that case, experts say you should move to a cooler area and hydrate.

Heat stroke typically looks like confusion, lack of sweat, hot/red skin, and a rapid heartbeat. At that point, doctors urge you to seek medical attention or call 911.

Brooklyn residents are reminded to stay hydrated today, opt for shaded areas, and to limit strenuous activity outdoors.
