“…The number of participants who responded that they never or only occasionally use hurricane warning graphics made up 61% of the participants. This is a stark contrast to the more frequently impacted Pensacola, Florida (Radford et al ., ).…”

“…By displaying multiple hazard information within the same graphic, the information could be communicated efficiently to reduce time and keep the attention of participants during a long survey. Each scenario depicts the tropical cyclone several days from making landfall using the cone of uncertainty (COU) (Matyas et al, 2011;Radford et al, 2013). The wind radii and storm surge maps were purposefully depicted in the form of forecast maps to show the effect each hazard would have over the study area.…”

“…The top left panel included the track of the storm with the associated NHC COU. The COU was used in these graphics because it is the most commonly used graphic to depict the probable path of a hurricane and it is used operationally, despite its shortcomings (Broad et al, 2007;Eosco, 2008;Radford et al, 2013).…”

ABSTRACT:The mid-Atlantic region of the United States is susceptible to tropical cyclone hazards. Within the past 15 years this region has experienced Hurricane Isabel in 2003, Hurricane Irene in 2011 and several tropical storms. The region was also impacted by post-tropical Sandy in 2012. The perception of hurricane hazards among residents of the mid-Atlantic region has not been directly researched. Furthermore, there is a lack of research on the comprehension of information from hurricane warning graphics that influences hazard perception. This research used a total of eight hypothetical scenarios (four pairs) that varied storm track and storm size to assess risk perception of hurricane hazards and characteristics. Each scenario was represented using a four-panelled map featuring the National Hurricane Center's cone of uncertainty, a new storm surge map and a new damaging wind map created by the authors. A Qualtrics survey was used to collect responses to questions about concern for personal harm and evacuation intent. Residents of the region perceived falling trees, potential for damaging winds and the size of the storm to be the greatest threats. Scenarios depicting larger storms with track lines that moved inland were seen as more hazardous, resulting in greater concern and evacuation intent. Coastal residents showed greater concern about distance from the track for all scenarios and greater evacuation intent for larger storms compared to inland residents.

“…The method in which hazard information is conveyed through warnings and graphics can also affect how individuals perceive data to inform their decision to evacuate. It has been observed that the type of graphic presented to an individual can influence their protective action decisions and that different methods of information portrayal with natural hazards can alter an individual's risk perception [41][42][43][44]. For example, the study by Ash tested the response to three different tornado warning designs [41].…”

“…Research into dynamic and other graphics has also shown that the use of probabilistic hazard information included within graphics can enhance the effectiveness of the warning [45,46]. Specifically with hurricanes, there has been research conducted to address graphical changes to popularly used communication tools such as the cone of uncertainty [44].…”

Geophysical and Social Influences on Evacuation Decision-Making: The Case of Hurricane Irma

et al. 2020

Understanding the factors that influence evacuation decision-making among local residents is of critical importance to those involved in monitoring and managing weather-related hazards. This study examined both geophysical and social variables that we believe influenced individual decision-making on whether to stay home, seek out a public shelter, or leave the area entirely during Hurricane Irma. A 23-item survey was administered to a convenience sample of adults (n = 234) who resided within a coastal Florida county that received an evacuation warning during Hurricane Irma in 2017. Results suggested sources of information relied on through media, government, family, and social networks contributed to differences in evacuation behavior. Moreover, potential exposure to weather-related conditions, such as flooding and strong winds, along with the likelihood to use available social resources, also influenced decisions to stay or leave the threatened area. Finally, prior evacuation behavior was significantly associated with the decision to evacuate during Hurricane Irma. The decision to evacuate for Hurricane Irma was shown to impact decision-making to evacuate for major hurricanes in the future. If these findings are applied to future storms, a broader conclusion can be made that residents in vulnerable areas may be more likely to evacuate for major hurricanes than they were in the past. Improved understanding of evacuation decision-making can assist emergency managers in preparation and planning to reduce casualties resulting from a hurricane or other weather-related hazard.
