Final answer:

A flood warning is issued when flooding is imminent or occurring because it alerts individuals and communities to take immediate action to protect themselves and their property.

Explanation:

This warning is typically issued by meteorological agencies or local authorities based on observations, forecasts, or data indicating significant rainfall, rising water levels in rivers, or other conditions conducive to flooding. By issuing a flood warning, authorities aim to minimize the risk of injury, loss of life, and property damage by prompting people to evacuate flood-prone areas, implement flood preparedness measures, and stay informed about the evolving situation. Timing is critical in issuing flood warnings to ensure timely response and mitigation efforts.
