IMD issues district-level impact-based heatwave forecasts and early warning systems
District-level heatwave impact forecasts and early warning systems strengthen India’s heat-risk governance
- The India Meteorological Department issues heatwave warnings at the district level and disseminates them through digital, media, and institutional channels.
- The Hazard and Vulnerability Atlas of India provides district-wise vulnerability assessment for heatwave hazards.
- Heat Action Plans are being used in many parts of India to provide advance warnings and preventive guidance for heatwaves.
The India Meteorological Department (IMD) has said that it now issues district-level impact-based forecasts (IBFs) for heatwaves twice a day. The warning system matters because it does not only predict heat conditions; it also communicates expected impacts and suggested actions for mitigation.
The government says this system is being used with National Disaster Management Authority (NDMA) guidelines, Heat Action Plans, and multi-channel dissemination to disaster managers, government departments, the media, and the public.
What changed now
UPSC can ask how impact-based forecasting, district vulnerability mapping, and Heat Action Plans improve preparedness for extreme heat. The topic links geography, disaster management, public health, labour vulnerability, and Centre-State coordination.
