🌀 5. METEOROLOGICAL ANALYSIS (Based on 0530 IST – 23 Nov 2025)

The following large-scale weather systems are influencing the country:

🔸 Low Pressure Area Over Strait of Malacca

  • A Well-Marked Low Pressure Area lies over the Strait of Malacca & adjoining South Andaman Sea.

  • This system, along with an associated cyclonic circulation extending up to 7.6 km above mean sea level, is expected to:

    • Move west-northwestwards.

    • Intensify into a Depression over the southeast Bay of Bengal and south Andaman Sea by 24th November.

    • Potentially strengthen further into a Cyclonic Storm over the southeast Bay of Bengal within 48 hours.

This system is the primary driver behind heavy rainfall in the southern coastal regions.

🔸 Upper Air Cyclonic Circulations

1. East Bangladesh & Neighbourhood

  • Cyclonic circulation up to 1.5 km above mean sea level.

  • Continues to provide moisture inflow into eastern India.

2. Southeast Arabian Sea

  • Cyclonic circulation extending up to 3.1 km above mean sea level.

  • Supporting rainfall over Kerala, Lakshadweep, and coastal Karnataka.

3. Comorin Area & Adjoining Indian Equatorial Ocean

  • Cyclonic circulation up to 1.5 km height.

  • Enhancing cloud development and rainfall over Tamil Nadu and Kerala.

These combined systems are strengthening moisture convergence and increasing rainfall probabilities across the southern coast and Bay region.

🌦️ 6. Weather Outlook for the Next 3 Days

Widespread Rainfall Expected

  • Tamil Nadu, Kerala, and the Islands (Lakshadweep & A&N Islands)
    Fairly widespread to widespread rainfall activity is likely, with thunderstorms at multiple locations.

Isolated to Scattered Rainfall

  • Coastal Andhra Pradesh

  • Coastal Karnataka

  • South Interior Karnataka

These regions will observe moderate rainfall activity with occasional thunderstorms.

📝 Conclusion: What to Expect This Week

  • South India will continue to see intense rain spells, especially Tamil Nadu, Kerala, and the Andaman–Nicobar region.

  • A developing system over the Bay of Bengal may evolve into a cyclonic storm, causing significant weather impact.

  • North and Northeast India will experience falling temperatures and persistent fog.

  • Fishermen and coastal communities should remain alert to strong winds and rough sea conditions.
