The question of how to best evaluate and communicate the value of weather warnings was addressed by a survey. This included questions with respect to the relevance of various aspects of a warning, the potential benefit of providing information on warning quality, the type of useful information and suitable ways of providing such information. Apart from the core information of warnings (time, place and severity) impact information and behavioural advice are seen to add value to a warning.

At MET Norway, a small interdisciplinary team – the Sandbox – tries to improve the communication between the meteorologists and their audience. In 2021, we focused on the communication of forecast uncertainty. The Sandbox created, with input from internal and external experts, solutions for applying linguistic and visual tools for forecasters to communicate about uncertainty. In the article, we share our experiences and lessons learned.
