This project provides clean GeoJSON shapes of Swiss lakes, ready for use in maps and visual tools. The data can be integrated into web applications to display accurate lake outlines and support clearer geographic visualization, including lake specific storm warnings.

sturmwarnung.online gathers weather alerts from several independent sources and presents them in a clear, mobile friendly view. It works as a live monitor that helps you decide if it is safe to head out on the lake or better to stay ashore.
