Torrential rain refers to an intense and heavy downpour of rain that occurs in a short period. This type of rainfall can lead to significant water accumulation, often resulting in flooding. It is typically associated with severe weather conditions, such as thunderstorms or tropical storms, and can cause damage to infrastructure and the environment. During torrential rain, the rate of precipitation can exceed 2.5 inches per hour. This rapid accumulation can overwhelm drainage systems, leading to waterlogged streets and hazardous driving conditions. Areas prone to flooding or located near rivers are particularly vulnerable during such weather events.
