A well-marked low-pressure area over the southeast Bay of Bengal has concentrated into a depression, the India Meteorological Department (IMD) said in its bulletin on Saturday, October 31 — turning the forecast Awaaz Punjab reported on October 29 into an active storm system now moving towards the Andhra Pradesh coast.

What IMD expects next

The system is very likely to move west-northwestwards and intensify into a deep depression over the southeast Bay of Bengal within the next 12 hours, and then into a cyclonic storm during the following 12 hours, reaching the west-central Bay of Bengal near the Andhra Pradesh coast around the evening of November 2, according to the IMD bulletin.
