BROOKLYN - Cooling centers opened across the city today as a heat wave swept over the borough.

The high temperatures and humidity left residents looking for ways to beat the heat. At a Crown Heights cooling station, Mayor Michael Bloomberg dropped in to see how some were coping.

Resident Jose Gonzales says he rode his bike to the boardwalk in Coney Island to catch a breeze from the water. Other beachgoers say they took the day off from work to get some sun and stay near the water.

Officials from the city's Office of Emergency Management are urging residents to call their doctor or head to the hospital if they are feeling sick. They say everyone should be aware of the symptoms associated with heat exhaustion, which include nausea, difficulty breathing and disorientation.
