In cyclone-prone areas, the India Meteorological Department (IMD) plays a crucial role in safeguarding communities by issuing color-coded weather warnings. These warnings serve as a visual language, conveying the severity of impending cyclones and guiding residents, emergency responders, and authorities in making informed decisions. The color-coded system is designed to communicate the potential impact and urgency of the approaching cyclone, offering a concise and universally understood means of relaying vital information. Understanding the meaning behind these color codes is essential for residents to prepare adequately and respond effectively to the dynamic and often hazardous weather conditions that cyclones bring. In this context, the color-coded warnings become a lifeline, empowering individuals and communities to navigate the challenges posed by cyclones with a heightened sense of awareness and readiness.
