Health Impacts of Extreme Weather Events
As communities across the United States are faced with extreme weather events, local health departments are uniquely positioned to identify, prevent, and respond to the health impacts from these events. NACCHO aims to provide resources to ensure local health departments are equipped to take on this role, while elevating best practices and success stories at the local level.
NACCHO and the Health Group of CMEC (University of Vermont, University of Washington, University of Nebraska) are excited to present an interactive in-person preconference workshop on July 14, 2026, at the Kentucky International Convention Center in Louisville, KY as part of the NACCHO360 Annual Conference. The workshop is designed to help local health departments identify opportunities to standardize climate and health risk assessments while respecting each community’s unique context and priorities.

Below are some of the most recent webinars hosted by NACCHO related to the health impacts of extreme weather events.
Test a New Virtual Tool: Plan and Implement Protective Extreme Heat Interventions (July 2025)
NACCHO and the University of Washington REACH Center hosted a webinar about CHaRT, a tool to reduce health risks associated with extreme heat. CHaRT can be used by local health departments to assess and plan for extreme heat events in the regions they serve. CHaRT is an online tool that provides data on heat-health risks at a local scale for both historical and future conditions. It can provide tailored risk reduction activities based on local factors, and information about the efficacy, timing and cost of each intervention. This webinar discussed an opportunity for health departments to participate in a research trial on CHaRT. The research trial will help UW researchers learn more about the tool’s effectiveness in helping local health departments prepare for heat.
