Abstract

Tornado watches are issued by the National Weather Service when conditions are favorable for tornado formation. Individuals' responses to a tornado watch may affect their ability to seek shelter before a tornado strikes. Here, survey data of Tennessee residents were used to determine common patterns in intended responses to two tornado watch scenarios: one during daytime, and the other at nighttime. Three common patterns were identified for a daytime watch: doing nothing, seeking information using technology, or seeking shelter and praying for safety. The two patterns for a nighttime watch were either to do nothing or to react actively by seeking further information, seeking shelter, and contacting friends and family. Logistic regressions indicated younger participants, those with prior tornado experience, and those who understood a tornado watch were less likely to intend to seek shelter and pray for safety during the daytime. Older participants and those without strong self-efficacy beliefs were less likely to use technology to find further information. For the nighttime scenario, participants living in east Tennessee and those who believed that bodies of water provide protection from tornadoes were more likely to respond actively, while wealthier participants and those living in single- or multifamily houses were less likely to respond actively. These results show that intended watch response is influenced by many factors, including age, income, and self-efficacy beliefs, as well as knowledge of and experience with tornadoes. In addition, those who do not understand the meaning of a tornado watch may be more likely to seek shelter prematurely. Significance Statement We sought to determine common intended responses to tornado watches, a type of alert that indicates conditions are favorable for tornadoes over the next few hours, among the public. We then analyzed which participant characteristics were associated with these common response types. Age, income, housing type, belief in tornado myths, knowledge of watch terminology, and belief that one's own actions affect tornado survival likelihood were all significantly associated with common response types. These findings are important for forecasters, broadcasters, and others responsible for alerting the public for severe weather. Clarifying tornado watch terminology, dispelling myths, and specifying where those in mobile homes can find shelter are all important strategies for a better-prepared public.
