A rainfall warning is an advisory issued by meteorological agencies to alert the public and authorities about anticipated heavy rainfall in a specific region. This warning is crucial in situations where intense or prolonged rainfall can lead to various hazards such as floods, landslides, and flash floods. The warnings often provide information on the expected amount of rainfall, potential impacts, and safety measures that individuals and communities should take. Meteorological services use weather forecasting models and real-time data to issue timely and accurate warnings, allowing people to prepare and take necessary precautions to minimize risks associated with heavy rainfall events.
