200 mm of rain refers to a volume of precipitation. In meteorological terms, it means that if you were to collect all the rain that fell over a square meter during a storm, it would fill a container to a height of 200 millimeters. To put it into perspective, it's about 8 inches of rain. This amount of rain can lead to significant flooding, especially in areas where the ground cannot absorb water quickly or where drainage systems are inadequate.
