India, with its vast coastline, diverse geography, and monsoon-dependent climate, faces hundreds of extreme weather events every year — from cyclones and floods to heatwaves and droughts. Over 75% of districts are exposed to multiple climate hazards, making disaster preparedness not just important, but essential.
In January 2024, the India Meteorological Department (IMD) launched the Multi-Hazard Early Warning Decision Support System (MHEW-DSS) — a landmark digital transformation under Mission Mausam. This system marks a decisive shift from fragmented forecasting to an integrated, automated, and impact-based approach that protects lives, livelihoods, and infrastructure.
What Makes MHEW-DSS Different?
- Impact-Based Forecasting: Explains how weather will affect people, sectors, and communities.
- Real-Time Alerts: Forecast preparation time cut by 50%, accuracy improved by 30%.
- Wider Reach: Location-specific warnings now cover nearly 80% of India’s population.
- Cost Savings: Evacuation costs reduced to one-third compared to 1999.
- Self-Reliance: Built in-house, saving ₹250 crore and reducing dependence on foreign vendors.

Success Stories
During Cyclone Biparjoy and Cyclone Dana, MHEW-DSS enabled timely evacuations in Gujarat and Odisha — resulting in zero casualties.Farmers using IMD’s agromet advisories reported 52.5% higher annual income compared to those who did not. If extended across rain-fed districts, the economic benefit could reach ₹13,331 crore annually.
How It Works
- Satellite, radar, and ocean buoy data integration
- GIS-based maps for visualization
- Multi-model forecasting with bias correction
- Colour-coded warnings for easy public understanding
