text:  Well, heat exhaustion, of course, is a serious concern. The city and county have opened multiple cooling centers and are offering free transportation to and from those centers. Folks can call 3-1-1 if they need a ride. The heat also means those field crews from CenterPoint working on power lines need to take more frequent breaks. There is a chance, though, of some relief from the heat with rain in the forecast for today and tomorrow.
