• Recently, Cyclone Jawad has hit the east coast of India particularly the State of Odisha and Andhra Pradesh.
  • Although the cyclone weakened and didn’t cause much damage, it highlighted that India’s cyclone management approach was largely based on evacuation.
  • Thus, India’s cyclone management must incorporate Mitigation and Preparedness measures. Mitigation means measures taken prior to the impact of a disaster to minimize its effects.

Important points:

  • Cyclones are rapid inward air circulation around a low-pressure area. The air circulates in an anticlockwise direction in the Northern hemisphere and clockwise in the Southern hemisphere.
  • Cyclones are usually accompanied by violent storms and bad weather.
  • The word Cyclone is derived from the Greek word Cyclos meaning the coils of a snake.
  • It was coined by Henry Piddington because the tropical storms in the Bay of Bengal and the Arabian Sea appear like coiled serpents of the sea.
  • Too little attention being given to key disaster response functions other than evacuation.
  • The current threat from Cyclone Jawad, which comes at a time when crops in most parts are nearing harvest.
  • There was distress selling and premature harvesting because of the cyclone.


  • Hazard mapping for cyclones represents the results of cyclone hazard assessment on a map, showing the frequency/probability of occurrences of various intensities or durations.
  • Policies should be in place to regulate land use and enforcement of building codes.
  • Vulnerable areas should be kept for parks, grazing grounds or flood diversion instead of human settlements.
  • Some examples of general good construction practice include:
  • Constructing buildings on stilts or on earthen mounds.
  • Buildings should be wind and water resistant.
  • Buildings storing food supplies should be protected against the winds and water.
  • Cyclone Shelters are necessary for areas vulnerable to recurrent cyclones.
  • The construction of cyclone shelters requires substantial funding, therefore, generally linked to support from government or external donors.
  • For construction of cyclone shelters, the most appropriate sites should be selected, using the Geographical Information System.
  • Flooding will result from a cyclonic storm. Storm surges will flood the coastal areas. Heavy rains will bring in flash floods.
  • Embankments along the rivers, sea walls along the coasts may keep water away from the flood plains.
  • Water flow can be regulated through construction of reservoirs, check dams and alternate drainage channels/routes.

Color Coding of Cyclones:

  • It is a weather warning that is issued by the India Meteorological Department (IMD) to alert people ahead of natural hazards.
  • The four colors used by IMD are Green, Yellow, Orange, and Red.
