RIVERSIDE With temperatures expected to rise as summer approaches, health officials are opening dozens of cooling centers across Riverside County as a way to protect residents from excessive heat. The centers are available at no cost and provide a break from the sometimes triple-digit temperatures that can bake the region. The National Weather Service is predicting 100-plus degree temperatures in some portions of Riverside County this week. High temperatures can be hazardous for many people, especially for the elderly and those with medical conditions. Heat-related injuries such as heatstroke, an illness that occurs when the body can no longer regulate its temperature, can strike fast and pose life-threatening consequences. The cool centers are coordinated by the Community Action Partnership of Riverside County, in conjunction with the health department, and are located in local libraries, senior and community centers. Light refreshments and water will be available at some locations. For a list of cooling center locations, visit http://www.rivcohealthdata.org/home/index.php/cool-centers
