Pre-Disaster – Cyclones

Cyclone warnings are issued by the Indian Meteorological Department (IMD) in four stages:

  1. Pre Cyclone Watch (First Stage): This warning, issued 72 hours in advance, provides early alerts about the development of a cyclonic disturbance and its potential intensification into a tropical cyclone.
  2. Cyclone Alert (Second Stage): Issued at least 48 hours ahead, this stage offers information on the storm’s location and intensity, its likely path, expected intensification, coastal districts at risk of adverse weather, and guidance for fishermen, the general public, media, and disaster management authorities.
  3. Cyclone Warning (Third Stage): This warning, released at least 24 hours prior to expected adverse weather, includes the forecasted landfall point, updates on the cyclone’s position and intensity every 3 hours, predictions for heavy rainfall, strong winds, and storm surges, and provides advice to the public, media, fishermen, and disaster management agencies.
  4. Post Landfall Outlook (Fourth Stage): Issued at least 12 hours ahead of the predicted landfall, this stage offers insights into the cyclone’s post-landfall movement direction and the anticipated adverse weather conditions in inland areas.

These warnings are color-coded as follows:

  • No Warning: Green
  • Cyclone Watch: Yellow
  • Cyclone Alert: Orange
  • Cyclone Warning: Red


After a cyclone strikes, damage assessment and relief efforts become essential:

  1. Assessment Committee: Formed to identify missing persons, casualties, injuries, and assess property damage, livestock loss, crop damage, and other impacts for effective relief planning.
  2. Debris Clearance: Removing debris, fallen trees, and restoring power lines require a substantial effort and additional manpower mobilization.
  3. Casualty Management: Teams for handling deceased bodies and carcasses must be organized promptly in areas with high casualties.
  4. Food Disposal: Spoiled food items on roads need proper disposal to prevent health hazards.
  5. Air Drops: Consideration may be given to air-dropping food and essential supplies to inaccessible areas affected by cyclones and heavy rainfall, coordinated by the district administration.
  6. Food Arrangements: Food provision at accessible locations and shelters is crucial. Both cooked and dry food should be available for those affected.
  7. Clothing and Blankets: Ensuring the dignity, safety, and well-being of affected individuals by providing sufficient clothing and blankets, with special attention to children, the sick, elderly, women, and widows.
  8. Road Restoration: Immediate efforts should be directed toward restoring roads to a drivable condition, including the mobilization of earth-moving machinery like JCBs and tractors.

In the face of a cyclone, proactive disaster management measures are essential to minimize damage and facilitate efficient recovery.
