At 8:30 am IST, the depression was centred near latitude 19.4°N and longitude 81.9°E, approximately 40 km north-northwest of Jagdalpur in Chhattisgarh. It had moved northwards at a speed of around 18 kmph during the preceding six hours.

Fresh Low-Pressure Area Over South Andaman Sea Likely to Intensify
Meanwhile, a separate low-pressure area persisted over the south Andaman Sea and neighbouring areas as of 8:30 am on October 29.
According to the IMD, the system is likely to move west-northwestwards and intensify into a well-marked low-pressure area over the south Andaman Sea and adjoining Andaman and Nicobar Islands during the next 24 hours.
Thereafter, it is expected to continue moving west-northwestwards and concentrate into a depression over the southeast Bay of Bengal, adjoining Andaman and Nicobar Islands and the Andaman Sea during the subsequent 24 hours.
The development of this system will be monitored closely as it progresses over the Bay of Bengal region.
The IMD’s latest assessment indicates that the remnants of Cyclone Arnab are expected to weaken further over central India, while the separate system over the south Andaman Sea could strengthen over the next two days.
