IMD’s cyclone Decision Support System: what happened?

India’s cyclone forecasts are now good; the weak link is turning a bulletin into action in a district control room. A map that shows where the storm may go and what it will do there is meant to close that gap.

  • The India Meteorological Department (IMD) dedicated its Cyclone Warning and Marine Weather Services Decision Support System (DSS), an interactive WebGIS platform, to the nation on 12 October 2026.
  • It shows cyclone track and intensity with a cone of uncertainty, winds, district-wise rainfall warnings, storm surge and rainfall forecasts for river catchments.
Back Story

What is the Pre-Cyclone Exercise Meeting?

  • IMD has held it twice a year since 2008 to review preparedness before each cyclone season and check action on earlier decisions.
  • This edition had about 230 participants from more than 30 organisations, including NDMA, NDRF, the Navy, Air Force, Coast Guard, Central Water Commission and coastal States.
  • The date recalls Very Severe Cyclonic Storms Phailin (2013) and Hudhud (2014), both of which crossed the coast on 12 October.
Why examiners care

Why does IMD’s cyclone Decision Support System matter?

  • Disaster management: Location-specific hazard information for faster evacuation decisions.
  • Fisheries and shipping: Marine weather on the same platform for coastal users.
Exam Radar

What can Prelims ask on IMD’s cyclone Decision Support System?

  • IMD is under the Ministry of Earth Sciences.
  • Cone of uncertainty: the likely spread of a cyclone’s future track.
  • Storm surge: abnormal rise of sea water pushed ashore by cyclone winds.
  • Phailin (2013) and Hudhud (2014) crossed the coast on 12 October.
