Abstract

This dissertation investigates the effectiveness of current hurricane warning products and communication strategies, exploring factors influencing public perception of risk and decision-making during evacuations. The study employs a mixed-methods approach, combining survey data, focus group discussions, and interviews with meteorologists and emergency managers. The first paper examines the impact of the COVID-19 pandemic on hurricane risk perception and evacuation decisions. Findings indicate that while COVID-19 concerns played a role in some individuals' decisions, particularly those with pets or concerns about shelter conditions, the majority of participants evacuated for Hurricane Ian. The study highlights the importance of providing clear, consistent, and timely information during evacuations, even in the context of a public health crisis. The second paper delves into public perceptions of hurricane risk, revealing a spectrum of emotions and concerns beyond wind speed. It proposes a shift towards audience-centered communication strategies, emphasizing the need for separate rating systems for wind, surge, and rainfall, tailored to diverse information needs. The research highlights the importance of accessible visuals, transparent calculations, and personalized information delivery to empower individuals and improve decision-making. The third paper investigates the effectiveness of current hurricane warning products and communication strategies through interviews with meteorologists and emergency managers. Findings reveal challenges in public understanding, including the limitations of the Saffir-Simpson Hurricane Wind Scale (SSHWS) and the need for more comprehensive risk assessment. The study proposes recommendations for improvement, such as simplifying messaging, strengthening local-level communication, and tailoring content to diverse audiences. By combining these three papers, this dissertation offers a comprehensive understanding of the factors influencing hurricane preparedness and decision-making. The findings provide valuable insights for policymakers, emergency managers, and communicators seeking to enhance public safety during hurricane events.
