New Low-Pressure Area Forms in Andaman Sea Following Cyclone Arnab, IMD Warns Potential Impact on Andhra Pradesh

A fresh low-pressure area has formed over the south Andaman Sea just a day after Cyclone Arnab crossed the coast of Andhra Pradesh, with officials from the India Meteorological Department (IMD) stating it could potentially affect the State.

According to the IMD in Amaravati, the low-pressure system developed under the influence of a cyclonic circulation. Meanwhile, the remnant of Very Severe Cyclonic Storm “Arnab” weakened into a depression over south Chhattisgarh and adjoining south Odisha, moving northwards and causing widespread rainfall across multiple states.

Weather System Status and Forecast

• Andaman Sea System: Formed on October 29, 2026, the system is expected to move west-northwestwards, potentially becoming a well-marked low-pressure area over the south Andaman Sea and adjoining Andaman and Nicobar Islands, and later concentrating into a depression over the southeast Bay of Bengal.
• Cyclone Arnab Remnant: The depression was centered near Jagdalpur in Chhattisgarh, moving north at 18 kmph, and was expected to weaken further into a well-marked low-pressure area.
• Rainfall Impact: Exceptional heavy rainfall was recorded in parts of south Odisha, such as Patrapur (Ganjam district) registering 546 mm. The IMD has forecast heavy rain at isolated places in coastal Andhra Pradesh for November 1, 2, and 3.

Practical Implications and Election Schedules

• Civic Polls: Urban local body elections in Andhra Pradesh remain scheduled for November 1, which coincides with the IMD's heavy rain forecast.
• Rural Polls: MPTC and ZPTC elections have been rescheduled to November 5 by the State Election Commission due to staffing constraints for vote counting.
