This study aims to examine how humour can be used as a communication strategy in a crisis communication work with an objective of creating crisis awareness among the target audience and through this, contribute to the research field of Strategic communication and digital media. Research concerning humour as a strategy combined with risk communication is yet limited and therefore this paper has the ambition to contribute with new knowledge about whether humour as a strategy is appropriate and successful when transmitting a preparatory crisis message, that can be seen as a topic difficult to relate with for the target audience. The empirical material is limited to a digital advertising campaign. The campaign was launched in December 2019 by the Swedish Civil Contingencies Agency (MSB) on Swedish television and social media channels and consists of three videos from the campaign. Based on theories that concerns national risk- and crisis communication, humour as a strategy, national humour and social norms, a multimodal critical discourse analysis (MCDA) has been implemented on the empirical material to find out whether the producer’s lexical choices, representation of the characters and power relations can contribute with knowledge that regards if humour can work as a strategy, in a situation where a crisis doesn’t exists yet. The result shows that humour can work as a strategy if it is being used with caution and if the producer takes the specific context, culture and the target audience's earlier experiences of crisis into consideration, when adapting the preparatory message.
