The bill amends Chapter 30-15 of the General Laws regarding "Emergency Management" by introducing new sections that establish protocols for issuing warming and cooling center alerts. It requires municipalities to create plans for alerting local agencies and organizations about the availability of warming and cooling centers during extreme weather conditions. The Director of the emergency management agency is tasked with declaring these alerts based on weather forecasts from the National Weather Service, which include specific temperature thresholds for both cold and heat.

The bill defines "at-risk individuals" and outlines the responsibilities of municipalities during these alerts, including ensuring that shelters are open 24/7, providing necessary resources for comfort, and coordinating with local social services. Municipalities receiving state or federal funding must keep their centers open during declared alert periods. Additionally, municipalities not identified as "hot spots" for homelessness may collaborate with neighboring municipalities to operate regional centers.

The act is designed to enhance support for vulnerable populations during extreme weather events and will take effect upon passage.
