A "Flood Warning" is an alert given when a river, lake, or coastline is about to overflow and potentially cause flooding in nearby areas. It is issued by authorities to inform people that flooding is expected, so they can take safety measures like moving to higher ground or protecting their homes. Flood warnings are based on weather forecasts and water level measurements, helping to reduce damage and keep everyone safe. It's a crucial part of managing and understanding natural events in geography, especially when studying how weather and water systems interact.
