CYCLONE ARNAB: DEVELOPMENT AND EXPECTED IMPACT:

  • Storm Intensification: Cyclone Arnab has developed into a severe cyclonic storm over the Bay of Bengal and is likely to intensify further into a very severe cyclonic storm.
  • Coastal Threat: The storm is moving towards the Andhra Pradesh coastline, raising concerns about strong winds, coastal flooding and potential damage to infrastructure.
  • Expected Landfall: The cyclone is expected to make landfall tomorrow morning, requiring coastal communities and disaster management authorities to remain alert.
  • Heavy Rainfall: Odisha, especially its southern districts, is likely to experience heavy to extremely heavy rainfall, increasing the risk of waterlogging and localised flooding.
  • Transport Disruptions: Several train services have been cancelled or curtailed as a precautionary measure to ensure passenger safety and minimise risks during the cyclone.

GOVERNMENT PREPAREDNESS AND DISASTER MANAGEMENT

  • Administrative Measures: The Odisha Government has intensified preparedness measures to address the potential impact of the approaching cyclone.
  • Public Safety: Timely warnings, evacuation of vulnerable communities where necessary, and access to emergency shelters are essential to minimise casualties.
  • Essential Services: Authorities must prepare emergency supplies, medical assistance, drinking water and backup power arrangements in potentially affected areas.
  • Transport Safety: Cancellation or curtailment of railway services helps reduce risks to passengers and railway infrastructure during severe weather conditions.
  • Disaster Response: Coordination among meteorological agencies, state governments, local administrations and emergency response teams is crucial for effective disaster management.

KEY POINTS : TROPICAL CYCLONES

●      Formation Conditions: Tropical cyclones generally develop over warm ocean waters, typically around 26.5°C or higher, with sufficient moisture and favourable atmospheric conditions.

●      Coriolis Force: The Coriolis force causes cyclones to rotate anticlockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

●      Indian Vulnerability: India’s eastern coast is particularly vulnerable to Bay of Bengal cyclones, which can cause storm surges, flooding and extensive infrastructure damage.

●      Warning Agency: The India Meteorological Department (IMD) monitors cyclones, issues forecasts and provides warnings to help governments and communities prepare.

●      Disaster Framework: Effective cyclone management combines early warning systems, evacuation, resilient infrastructure and community preparedness, consistent with the objectives of the Disaster Management Act, 2005.
