 Well, the National Weather Service has issued a heat advisory for Northern Rhode Island and parts of Massachusetts, including Bristol County. Providence Emergency Management Agency Director Clara DeSerbo says it's important to be aware of how you feel during a heat wave. Keep an eye out for symptoms of heat disorders or overexposure. So headaches, dizziness, feeling lightheaded or nausea. Those are signs that you've been in the heat too long and you need to get cool.
