Heavy downpour on a metallic surface.

As the audio begins, you can hear the powerful and persistent sound of rain, a heavy downpour, hammering against a metallic surface. Each drop of rain creates a resonant, sharp sound as it collides with the metal, creating a symphony of nature's power and the man-made world. This isn't a soft, gentle rainfall, but a forceful, commanding downpour that makes its presence known. Amidst this stormy weather, you can discern the unique, continuous drumming created by the raindrops hitting the metal. It's a rhythmic, almost hypnotic pattern, a testament to the intensity of the weather. The constant pouring of water on the metal dominates the audio, a vivid reminder of the relentless force of nature.
