Hurricanes vs Nor’easters: The Effects of Storm Type on Perceived Severity and Protective Actions

Abstract Both hurricanes and nor’easters can be destructive deadly. The current study investigates whether, when all other features of a storm warning message are held constant, people perceive the risks posed by differently whether these differences affect their attitudes decisions about taking protective action. We conducted an online experiment involving 1,700 Americans residing in northeastern coastal ZIP codes to test effects type (hurricane vs nor’easter). Participants were told that area was under evacuation order due either predicted hurricane or nor’easter. Reported comprehension perceived relevance similar across type; however, had small but significant on dependent measures. Those condition more likely believe would severe ( p = 0.007). They also say it is important evacuate, they evacuate homes, recommend neighbors < 0.001). Additional analysis demonstrated effect likelihood mediated, at least part, severity. These findings provide evidence as require action than nor’easters, even attributes storms remain same. Forecasters, broadcast meteorologists, emergency management professionals should consider perceptions communicating types storms.
