New Weather System Forms Over Bay of Bengal Following Cyclone Arnab

INSAT-3DS Captures Developing Cloud Formation

India's INSAT-3DS weather satellite has captured imagery of a newly organised cloud and thunderstorm system developing over the southeast Bay of Bengal and the Andaman and Nicobar Islands. According to reports published by India Today, the system emerged just days after Cyclone Arnab moved away from the eastern coast.

Satellite observations from Saturday morning, October 31, identified scattered to broken cloud cover with pockets of intense thunderstorm activity. The system originally formed as a low-pressure area over the South Andaman Sea and adjoining islands on October 29 before tracking west-northwestwards.

Meteorological Expectations and Forecasts

The India Meteorological Department (IMD) has reported that the system is expected to strengthen into a depression. However, official bulletins have noted the identification of a vortex while clarifying that the system had not yet officially been confirmed as a depression.

• Observed Activity: Intense thunderstorms and widespread rain over the South and North Andaman Seas.
• Projected Movement: Expected to track west-northwestwards towards the Andhra Pradesh coast over subsequent days.
• Coastal Impact: Scattered rain and thunderstorms forecast along the Andhra Pradesh coast with strengthening winds during storms.

Practical Implications and Verification

The developing weather disturbance carries the potential for further rain spells along parts of the Indian east coast. At the time of reporting, coastal bulletins contained no official port warnings or storm-surge advisories.

Because weather systems can shift in intensity and trajectory, observers and residents in affected coastal regions are advised to monitor official updates directly through the India Meteorological Department (IMD) website or local meteorological advisories for verified forecasts and tracking maps.
