IMD Launches Cyclone Warning and Marine Weather Services Decision Support System
On 12th October 2026, the India Meteorological Department (IMD) dedicated an interactive WebGIS-based Decision Support System (DSS) for cyclone warning and marine weather services. This system integrates critical weather data to aid disaster management authorities, government agencies, and the public in making informed decisions during cyclones and severe weather events.
IMD's new DSS platform enhances cyclone and marine weather warnings through interactive maps and real-time data, improving disaster preparedness and response.
Why is this in the news?
The IMD launched the Cyclone Warning and Marine Weather Services Decision Support System on 12th October 2026 during the bi-annual Pre-Cyclone Exercise Meeting chaired by the Director General of Meteorology.
What is the Cyclone Warning and Marine Weather Services Decision Support System?
- Interactive WebGIS platform. The DSS is a user-friendly, interactive platform that consolidates cyclone and marine weather information, including cyclone tracks, intensity, winds, rainfall, storm surge, and river catchment rainfall forecasts.
- Accessible to multiple users. It is designed for disaster management authorities, government agencies, and the general public to understand potential hazards and their impacts, facilitating informed decision-making.
- Available online. The platform is publicly accessible on the IMD website and the Regional Specialised Meteorological Centre (RSMC) website.
Why does this system matter for disaster preparedness?
- Bridges forecast and action gap. The DSS helps translate weather forecasts into practical use by providing location-specific hazard information, enabling timely action and enhanced public safety during cyclones.
- Supports inter-agency coordination. The system was launched during a meeting involving over 30 organizations and 230 participants from disaster management, defence, state governments, and scientific institutions, fostering collaboration.
- Builds on past successes. IMD's accurate predictions of Very Severe Cyclonic Storms Phailin (2013) and Hudhud (2014) have earned international recognition, highlighting the importance of improved early-warning systems.
How does the Pre-Cyclone Exercise Meeting contribute to cyclone management?
- Bi-annual preparedness review. Since 2008, IMD conducts this meeting twice a year to review preparedness for the upcoming cyclone season and assess progress on previous action points.
- Platform for stakeholder engagement. The meeting includes participation from disaster management authorities, defence forces, state governments, scientific organizations, and various ministries to strengthen coordination.
- Demonstration and feedback. The launch of the DSS included a live demonstration followed by stakeholder feedback to improve the platform's operational utility.

Back to basics: Cyclone Warning Systems
Cyclone warning systems use meteorological data to predict the formation, path, and intensity of cyclones. These systems provide early warnings to authorities and the public to prepare and respond effectively, reducing loss of life and property. Decision Support Systems integrate various data sources and present actionable information in an accessible format to aid decision-making during disasters.
Practice: MCQ, Mains and revision
Prelims MCQ
Consider the following statements about the IMD's Cyclone Warning and Marine Weather Services Decision Support System (DSS): 1. The DSS is an interactive WebGIS-based platform that provides cyclone and marine weather information including cyclone tracks, intensity, winds, and rainfall forecasts. 2. The DSS was launched during the annual cyclone season review meeting chaired by the Ministry of Home Affairs. Which of the statements given above is/are correct?
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
Answer and trap
Answer: (a). Statement 2 is incorrect because the DSS launch was during the bi-annual Pre-Cyclone Exercise Meeting chaired by the Director General of Meteorology, IMD, not the Ministry of Home Affairs.
Mains question (15 marks)
Examine how the IMD's Cyclone Warning and Marine Weather Services Decision Support System enhances disaster preparedness and management in India.
Examine: Explain the features of the DSS and its role in improving coordination and public safety during cyclones.
Intro: The IMD's Decision Support System integrates cyclone and marine weather data to aid disaster management.
- Describe the interactive features of the DSS and its accessibility to various stakeholders.
