DescriptionImpact-based severe weather warnings provide information about the expected impacts of potentially damaging weather events, in addition to the physical characteristics of the event, such as magnitude, location, and timing. Providing such additional information may help warning recipients make an informed decision and take appropriate actions. This study examined the effects of impact-based heatwave warnings on the recipients' risk perceptions and safety behaviors that potentially help reduce injuries and deaths. The results showed that the recipients were more likely to perceive a higher risk of a heatwave event when receiving the impact-based warnings than the traditional phenomenon warnings. However, impact-based heatwave warnings may not necessarily improve the recipients' behavioral responses.
