Preparatory Measures by Indian Coast Guard Ahead of Cyclone Remal

Preparatory Measures by Indian Coast Guard Ahead of Cyclone Remal


In anticipation of Cyclone Storm ‘Remal,’ the Indian Coast Guard (ICG) is undertaking comprehensive preparatory measures.

Gs-01 (Physical Geography)

About Cyclone Remal:

  • Cyclone Remal is forecasted to strike between the coasts of Bangladesh and West Bengal.
  • The depression over the Bay of Bengal is expected to escalate into a cyclonic storm, particularly in the east-central Bay of Bengal.
  • The cyclone is projected to hit the Bangladesh and West Bengal coastlines as a severe cyclonic storm, with wind speeds reaching up to 120 kilometres per hour as per the India Meteorological Department (IMD).
  • The cyclone will likely bring extremely heavy rainfall to the coastal districts of West Bengal and northern Odisha and to parts of northeast India.
  • Name and Meaning: Named ‘Remal’ by Oman, the term means ‘sand’ in Arabic.
  • The IMD anticipates a storm surge of approximately one metre above the astronomical tide inundating low-lying areas of coastal West Bengal, and 1.0-1.5 metres over Bangladesh at the time of landfall.

Mitigating the Impact of Cyclone:

IMD Advisories:

  • Complete suspension of fishing operations.
  • Regulation of surface transport and shipping activities.
  • Control of onshore and offshore operations as per established guidelines.
  • Avoiding outdoor activities in vulnerable regions.
  • Seeking shelter in safe locations.

ICG Coordination Efforts:

  • The ICG is collaborating closely with state administrations and relevant stakeholders to ensure a coordinated response to any contingencies arising from the cyclone.

Tropical Cyclones:

  • Violent storms originating over tropical oceans, tropical cyclones move towards coastal areas, causing extensive destruction with violent winds, heavy rainfall, and storm surges.
  • Favored conditions for their formation include a large sea surface with temperatures above 27°C, the Coriolis force, small variations in vertical wind speed, a pre-existing low-pressure area, and upper-level divergence.
  • Tropical Cyclone Stages:
    • Relies on the transfer of water vapor and heat from warm oceans, resulting in the formation of massive cumulus clouds
    • Mature Stage: Involves intensification with vigorous thunderstorms, generating a warm ‘eye’ at the center and highly turbulent cumulus thundercloud bands.
    • Weakening occurs when the source of warm, moist air diminishes, especially after landfall or passing over cold waters.
    • Nomenclature of Tropical Cyclones: Cyclones are named under the World Meteorological Organization’s guidance, involving contributions from countries in the region. For the Indian Ocean region, a naming formula involves eight contributing countries, including India, Bangladesh, and Sri Lanka.
    • Worldwide Terminology: Tropical cyclones are referred to differently globally, such as typhoons in the China Sea, hurricanes in the Caribbean, and tornadoes in West Africa and southern USA.

  • Extratropical Cyclones:
    • Also known as mid-latitude depressions or temperate cyclones, extratropical cyclones form above mid-latitudinal regions where polar and tropical air masses meet and create fronts. They are less violent than tropical cyclones and move from west to east.

Cyclones in India:

  • Tropical cyclones originating over the Bay of Bengal and Arabian Sea impact Indian coastal states.
  • These cyclones cause destruction through strong winds, torrential rains, and storm surges, affecting states like Tamil Nadu, Andhra Pradesh, West Bengal, Odisha, and Gujarat.
