To meet the individual needs requested by many expert users of warning products issued by the German Meteorological Service (Deutscher Wetterdienst / DWD), the idea of a new customizable branch for our future warning system (program RainBoW: "Risk-based, Application-oriented and INdividualizaBle delivery of Optimized Weather warnings) was born. Based on the prospects of a fully automatic warning system, the possibility of individual warning information can be realized by giving users the option to configure their own parameters and settings for warnings and reports.Based on results of a pilot project named "Kassandra", which marked the first attempt to conceptualize individual warnings at DWD and to determine the meteorological and technical requirements and challenges, a light-weight prototype of the warning portal was released at the end of 2022. The release was made available to a small amount of test users from different application areas to collect feedback and further requirements. Since then, a gradually increasing number of test users continues to evaluate further releases.The light-weight prototype of the warning portal does not yet provide full individualization capabilities for warnings and reports. However, we are planning to implement persistent warning profiles in one of the future releases, in which users will be able to configure warning location (position or geometries), period, warning element and criteria and also probabilistic or time-based thresholds. Using the wide range of available EPS models and other ensemble data sets at DWD, the user configurations will be analyzed periodically. Warnings or reports will be generated and sent to the users by mail or messenger (PUSH) in case of transgression. The system will also give users the possibility for PULL requests at any time by using the DWD warning portal or web API. Especially the web API will enable users to include individual warning information into their own automated processes by directly analyzing individual requests and returning the results as JSON.The poster presents concepts, components and configuration elements for the future provision of individualized warnings via the DWD warning portal.
