USA: Arizona's heat preparedness plan

This Plan outlines how state agencies are preparing for another extreme heat event this year, and puts forth recommendations for how the state can prepare for future events. The development of this Plan is a significant step forward in protecting Arizonans from the impacts of extreme heat and weather events, and would not have been possible without the contributions of state agencies, researchers, local governments, and faith-based and community-based organizations.
In 2023, Arizona experienced its hottest summer since record keeping began more than 100 years ago. In Maricopa County alone, more than 500 people died,1 and emergency rooms statewide recorded more than 4,000 heat-related visits. Cooling centers, which provide respite to people in need of safe shelter with consistent air conditioners and other cooling features, recorded more than 26,000 visits. Governor Hobbs issued Executive Order 2023-16 to galvanize partners, support emergency response, and implement new approaches to this growing challenge.
Extreme heat is a complex disaster that, left unchecked, impacts public health, economic productivity, quality of life, and the environment. This type of problem requires sustained attention and collaboration across jurisdictions, industries, and community partners.
