Full Form of SWW
What is SWW?
A Severe Weather Warning (SWW) is an official alert issued by meteorological authorities to inform the public about dangerous atmospheric conditions that could pose a threat to life, property, or daily activities. In India, the India Meteorological Department (IMD), operating under the Ministry of Earth Sciences, is the primary agency responsible for issuing severe weather warnings for events such as cyclones, heavy rainfall, thunderstorms, heatwaves, cold waves, and dust storms. These warnings are colour-coded into green, yellow, orange, and red categories to indicate the increasing severity of expected weather phenomena. SWWs are disseminated through the IMD website, mobile applications like Mausam and Damini, SMS alerts, All India Radio, and partner media outlets to ensure wide public reach across rural and urban India. Coastal states such as Odisha, Andhra Pradesh, Tamil Nadu, Kerala, and West Bengal, which are highly prone to cyclones and floods, rely heavily on these warnings for evacuation planning and disaster preparedness. The concept is important for aspirants preparing for UPSC, SSC, and state PSC examinations, particularly under general science, geography, and disaster management sections.
