IMD Tracks Cyclone Arnab Remnants and New Bay of Bengal System for Weekend Rain Across India

According to the India Meteorological Department (IMD), several parts of India are likely to experience rainfall on Saturday, October 31, driven by the combined influence of two major weather systems: the remnants of Cyclone Arnab and a developing low-pressure area over the Andaman Sea. Readers can verify official bulletins directly through the IMD's official channels.

Impact of Cyclone Arnab's Remnants

• Current Status: The system weakened from a Very Severe Cyclonic Storm into a well-marked low-pressure area and further into a standard low-pressure system over north Chhattisgarh and adjoining east Madhya Pradesh by Friday morning.
• Outlook: Although continuing to weaken, its associated atmospheric circulation and troughs are reported to sustain rainfall conditions across parts of central and eastern India.

Developing Low-Pressure System Over the Andaman Sea

• Location: A fresh low-pressure area lay over the South Andaman Sea and adjoining Andaman and Nicobar Islands on Friday morning.
• Forecast: The IMD indicates it is very likely to concentrate into a depression over the southeast Bay of Bengal around October 31 and move west-northwestwards toward the Andhra Pradesh coast over the subsequent two days.

Additional Weather Influences

• Circulations and Troughs: Other contributing factors include cyclonic circulations over north Punjab, South Gujarat, and Assam, alongside a trough extending from the east-central Arabian Sea toward central India.
• Practical Implications: The exact distribution and intensity of rainfall will depend heavily on the evolution and movement of the Bay of Bengal system over the next 48 hours.
