Let's draw a scene with heavy rainfall, accompanied by a tremendous flood.

Description:

The scene depicts a torrential downpour, with rain pouring down relentlessly from dark, ominous clouds overhead. Simultaneously, an immense flood is occurring, with water overflowing from a mountain, cascading down the slopes, and inundating the valley below. Rocks and trees are being swept away by the powerful current, and the landscape is engulfed in chaos and turmoil. The rain adds to the sense of urgency and danger as the floodwaters surge.
