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. Under the new provisions, municipalities are required to keep shelters or warming centers open 24/7 during extreme weather alerts, ensuring accessibility for at-risk individuals, defined as those living outdoors or in poorly insulated settings. The Director of the emergency management agency is tasked with coordinating these efforts, including the dissemination of information through various media channels and the development of consistent alert plans in collaboration with local emergency management coordinators.

Additionally, the bill mandates that municipalities provide necessary resources and comfort provisions at these centers, such as blankets and meals, during alerts. It allows municipalities not identified as "hot spots" for homelessness to collaborate with neighboring areas to operate regional centers. The act is designed to enhance support for vulnerable populations during extreme weather conditions and will take effect upon passage.
