Cyclone Montha Approaches Andhra Pradesh & Odisha

The India Meteorological Department (IMD) has issued warnings as Cyclone Montha, a severe cyclonic storm over the Bay of Bengal, moves closer to the Andhra Pradesh–Odisha coast. The cyclone is expected to make landfall within the next 24–36 hours, bringing with it winds exceeding 80 kmph, heavy to very heavy rainfall, and the risk of coastal flooding.

Both state governments have activated emergency response mechanisms to minimize casualties and infrastructural damage.

Background

• Formation: Cyclone Montha developed from a low-pressure area over the east-central Bay of Bengal, intensifying into a deep depression and later a severe cyclonic storm under favorable sea surface temperatures (~30°C) and low vertical wind shear.
• Naming: The cyclone was named “Montha” as per the WMO/ESCAP naming convention, following the rotational system among 13 member countries.
• Track: IMD forecasts the system to move northwestward toward the coasts of Andhra Pradesh and Odisha, with possible inland weakening thereafter.

Current Impact

1. High Winds & Rainfall:
   Coastal districts of Srikakulam, Vizianagaram, and Ganjam have reported wind speeds up to 80 kmph, uprooting trees and damaging power lines.
2. Evacuation Drives:
   Authorities have evacuated over 60,000 residents from low-lying and vulnerable coastal areas to relief shelters.
3. Transport Disruptions:
   Several trains and flights have been cancelled or rescheduled. Fishing operations remain suspended along the east coast.
4. Disaster Response:
   NDRF, SDRF, and local disaster response teams are deployed with boats, satellite communication, and medical supplies.

Preparedness Measures

• IMD Warnings: Continuous tracking through Doppler Weather Radars in Visakhapatnam and Gopalpur.
• State Coordination: Control rooms activated in all coastal districts.
• Electricity & Health Departments: Emergency restoration teams and medical units on standby.
• Public Awareness: Advisories issued through local radio, SMS alerts, and social media to avoid travel and sea ventures.

Environmental and Economic Implications

• Agriculture: Heavy rainfall may damage standing paddy crops, especially in delta regions.
• Fisheries: Cyclones disrupt marine livelihoods and coastal ecosystems.
• Infrastructure: Flooding, landslides, and erosion could damage roads, power lines, and housing, affecting local economies.

Scientific Perspective

• Bay of Bengal Cyclogenesis:
  The region accounts for nearly 70% of India’s cyclones due to warmer waters and favorable monsoonal wind patterns.
• Climate Change Link:
  Rising sea surface temperatures are making cyclones more intense and erratic, even though their overall frequency may not have risen proportionally.

Government and Institutional Mechanisms

• Nodal Agency: India Meteorological Department (IMD) under the Ministry of Earth Sciences.
• Disaster Management: National Disaster Management Authority (NDMA) and National Disaster Response Force (NDRF).
• Policy Framework:
  • Disaster Management Act, 2005
  • National Cyclone Risk Mitigation Project (NCRMP)
  • Sendai Framework for Disaster Risk Reduction (2015–2030)
