On hot days, a cooling center is more useful when residents already know how to reach it. That is why local organizers are using libraries, senior centers, and faith communities as the backbone of this summer's heat response.

The rooms offer air conditioning, water, seating, and a place to stay for a while. Outreach workers are also checking on people who live alone and residents whose homes may not have reliable cooling.

The schedule can change with the forecast. Residents should check before traveling, especially on weekends, and call emergency services if someone shows signs of a serious heat illness.
