23. Jul 2025


What does 50 liters of rain per hour actually mean for your home? The new Quarks video shows how you can use the HochwasserApp NRW app to assess your personal risk of heavy rain.

In the video, you will learn which factors determine why rain accumulates more heavily in certain areas and how you can protect yourself with practical protective measures—from severe weather warnings to 3D simulations of your environment. In view of increasing thunderstorms and heavier rainfall, good preparation is the best protection.
