Heavy rain refers to a significant amount of precipitation that falls within a short period. It is typically measured in millimeters or inches and can lead to various weather-related impacts. Heavy rain can cause flooding, soil erosion, and can disrupt transportation systems. It often occurs during storms or tropical systems, such as hurricanes or monsoons. Meteorologists use radar and satellite technology to track heavy rain events. The intensity of heavy rain can vary, with some storms producing rainfall rates exceeding 2.5 centimeters (1 inch) per hour. Areas prone to heavy rain, like tropical regions, often have specific seasons when such weather is more common.
