Information Dissemination, Diffusion, and Response during Hurricane Harvey
This article aims to build interdisciplinary understanding about modern hazard communication by investigating visual information dissemination, diffusion, and response leading up to and during a weather-related disaster. The study analyzes data from online social media posts by authoritative sources during Hurricane Harvey, focusing on forecast and warning tweets containing hurricane risk imagery. The research integrates quantitative and qualitat…
Integrating Place and Sense of Place into Geovisualizations of Hurricane Storm Surge Risk
Geovisualizations play a central role in communicating hurricane storm surge risks to the public by connecting information about the hazard to a place. Meanwhile, people connect to places through meaning, functions, and emotional bond, known as a sense of place. The mixed-method approach presented in this paper focuses on the intersection of sense of place, geovisualization, and risk communication. We explored place meaning, scale of place, and p…
Improving Tropical Cyclone Forecast Communication by Understanding NWS Partners’ Decision Timelines and Forecast Information Needs
As tropical cyclone threats evolve, broadcast meteorologists and emergency managers rely on timely forecast information to help them communicate risk with the public and protect public safety. This study aims to improve the usability and applicability of National Weather Service (NWS) forecast information in the context of these NWS core partners’ decisions during tropical cyclone threats. The research collected and analyzed data from in-depth in…
Agricultural Perspectives on Hailstorm Severity, Vulnerability, and Risk Messaging in Eastern Colorado
Eastern Colorado is one of the most active hail regions in the United States, and individual hailstorms routinely surpass millions of dollars in crop loss and physical damage. Fifteen semistructured interviews with eastern Colorado farmers and ranchers were conducted in the summer of 2019 to gauge perceptions of the severity and vulnerability associated with hailstorms, as well as to understand how forecasts and warnings for severe hail are recei…
Do We Know Our Own Tornado Season? A Psychological Investigation of Perceived Tornado Likelihood in the Southeast United States
Reducing fatalities from tornadoes in the southeastern United States requires considering multiple societal factors, including the risk perceptions that influence how people interpret tornado forecasts and warnings and make protective decisions. This study investigates perceptions of tornado risk in the southeastern United States, operationalized as judgments of tornado likelihood. While it is possible that residents of the Southeast could learn …
The influence of cultural worldviews on people’s responses to hurricane risks and threat information
This article explores whether and how cultural worldviews influence people’s responses to approaching natural hazard threats, using data from a survey that asked residents of coastal Florida, USA, about a scenario of a hurricane forecasted to affect their region. The analysis finds that stronger individualist worldview is associated with lower hurricane-related evacuation intentions, cognitive risk perception, negative affect, response and self-e…
“Sometimes da #beachlife ain't always da wave”
This article investigates the dynamic ways that people communicate, assess, and respond as a weather threat evolves. It uses social media data, which offer unique records of what people convey about their real-world risk contexts. Twitter narratives from 53 people who were in a mandatory evacuation zone in a New York City neighborhood during Hurricane Sandy in 2012 were qualitatively analyzed. The study provides rich insight into the complex, dyn…
Improving Coastal Storm Evacuation Messages
Evacuation before severe coastal storms is a critical tool for keeping coastal residents safe. Effective messaging of evacuations could help save lives, but there is little evidence-based guidance on the advantages or disadvantages of specific messaging. Ideally, evacuation messages would convince those most at risk to evacuate and those who do not need to evacuate to stay in their homes. Using an online survey of 1716 coastal residents in Connec…
The Effects of Past Hurricane Experiences on Evacuation Intentions through Risk Perception and Efficacy Beliefs
Individuals’ past experiences with a hazard can encompass many different aspects, which can influence how they judge and respond to a future hurricane risk. This study, which utilizes survey data from coastal residents who are at risk from hurricanes, adds to understanding of past hazard experience in two ways. First, it examines six different aspects of people’s past hurricane experiences and the relationships among them. Then, it draws on risk …
A Mental Models Study of Hurricane Forecast and Warning Production, Communication, and Decision-Making
The study reported here explores how to enhance the public value of hurricane forecast and warning information by examining the entire warning process. A mental models research approach is applied to address three risk management tasks critical to warnings for extreme weather events: 1) understanding the risk decision and action context for hurricane warnings, 2) understanding the commonalities and conflicts in interpretations of that context and…
Factors Affecting Hurricane Evacuation Intentions
Protective actions for hurricane threats are a function of the environmental and information context; individual and household characteristics, including cultural worldviews, past hurricane experiences, and risk perceptions; and motivations and barriers to actions. Using survey data from the Miami‐Dade and Houston‐Galveston areas, we regress individuals’ stated evacuation intentions on these factors in two information conditions: (1) seeing a for…
The Relationship of Weather Salience with the Perceptions and Uses of Weather Information in a Nationwide Sample of the United States
The authors used data from a sample of 1465 adults living in the United States to perform a confirmatory factor analysis on the Weather Salience Questionnaire (WxSQ), a 29-item instrument designed to measure the ways in which weather is psychologically significant for people. The original measurement model of the WxSQ was confirmed in the present sample. Additional work also was performed to create a WxSQ short form consisting of seven items. The…
Exploring Variations in People’s Sources, Uses, and Perceptions of Weather Forecasts
Past research has shown that individuals vary in their attitudes and behaviors regarding weather forecast information. To deepen knowledge about these variations, this article explores 1) patterns in people’s sources, uses, and perceptions of everyday weather forecasts; and 2) relationships among people’s sources, uses, and perceptions of forecasts, their personal characteristics, and their experiences with weather and weather forecasts. It does …
